USER NOTES

Everything enclosed in these "[ ]" is considered an important topic of debate and research. Also considered top priority over all other research projects for the dinosaurs.

 


Characteristics: Covered from head to toe in thick armor, only their underbelly is unprotected. Slightly orangeish in color, their armoring is a dark brown. Their tail also has a unique deAfense system located on the tip. A bony club on the end is used for defense against larger predators.)
Environment: Although originally thought to reside in the plains, it has proven difficult to determine what habitat the Ankylosaurs will fit into. Having a somewhat nomadic lifestyle, they seem to change their location every day, going from one area of the park to the next.
Feeding: Plant-eater. The Ankylosaurus feeds on low growing shrubs.
Habits: Extremely unintelligent, some concern has been expressed over the obvious stupidity of the animals. Even when confronted, the Ankylosaur does not seem to register any danger from its attacker, even though if a predator were to get an Anky onto its back, it would not be able to flip itself over again. Testing continues.
Ops Notes: More than once has the park staff been required to go out into the field and get an Ankylosaur back on its feet after they apparently tipped over onto their backs. Some experimenting has been done to redistribute the Ankylosaur's weight, but so far no improvements have been made.


Characteristics: Small and bat-like in build, the Anurognathus has a wingspan of just one foot, and is has a color range any where from light-orange to brown. Needle-sharp teeth line its distinctly dome-shaped jaw, and two small, curious eyes are located right near the back of its head.
Environment: Anurognathus is confined to its own cage, where it seems quite happy.
Feeding: The Anurognathus feeds in a manner similar to that of modern day bats. They swoop and dive through the air and, using their extremely well developed eyesight, snatch flying insects in their jaws, which are filled with needle sharp teeth.
Habits: The Anurognathus is generally most active around sunset, during the time when the insects are flying around. The rest of the day is usually spent redigging their nests in the rock walls or out patrolling their territory. Many InGen workers actually try to get all their work done before the Anurognathus come out to feed, so that they don't miss this amazing spectacle. Inside the enclosure, the air seems to literally be full of tiny Pterosaurs swooping and diving to catch their insect prey, and the flapping of their wings makes a sound similar to that of an applauding audience.
Ops Notes: Although not an emergency, a new food source needs to be found for the Anurognathus soon, if their population is to be kept at a constant level.

 

Characteristics: The Brachiosaur's front legs are distinctely longer than its hind ones, and its basic body build is similar to that of a giraffe, with a long neck, sloping back, and relatively small tail. The skull of the brachiosaur is also unique because of its strange shape. A long snout leads up to an amazingly sloped forehead, creating a slight crest for the animal, below which the eyes are located.
Environment: Due to its disproportionately large nostrils, it was originally hoped that the Brachiosaurus would reside mainly in the lagoon. Once immersed, however, the substantially higher water pressure at lower depths made breathing impossible. After a few tragic experiments, the decision was made to move the Brachiosaurus to the plains.
Feeding: Plant-eater. While the Brachiosaurus prefers to eat from tree tops, it has surprised everyone with a method of gathering food unique among the other dinosaurs. Using its front legs for support, the creature is able to "harvest" its meals from the grassy plains, tearing the foliage from the soil with its clawed hind legs.
Habits: Solitary nature. Some concern has been expressed over the creature's decidedly low libido. Testing continues.
Ops Notes: Aside from the (relatively) active exercise of gathering food, the Brachiosaurus has proven to be a disappointment in the personality department. It has proven difficult to maintain a healthy population, as many of the creatures have been dying suddenly. Cause of death remains a mystery.

 

Characteristics: Similar in most respects to the tyrannosaurus, the carnotaurs have a greenish base color, which shows up during mating season when the animals temporarily loose their camoflauge coloring (as described below). This is when the true form of the animal is revealed, and it can be seen that the carnotaur has extremely stubby forearms, completely useless for all but mating purposes. And possibly their most distinctive feature is a pair of protruding crests above each eye, possibly used for defense or as a mating display. Their heads are also unusually squarish in shape, giving them a somewhat bulldog-ish appearance.
Environment: Predominantly in the forest and jungle regions.
Feeding: Carnivore. Possibly the most interesting dinosaur in the park, the whole of InGen was rendered speechless when they discovered that this animal uses an ambush technique that has never before been observed in land animals. Their skin contains chromatophores that are sensitive to light changes. This allows them to blend in perfectly with their environment, becoming practically invisible. Being nocturnal predators, they can remain motionless for hours until some unsuspecting prey wanders too close.
Habits: Solitary hunters, the Carnotaurs will occasionally be seen in a pair bond, hunting, eating, and reproducing only with each other.
Ops Notes: Containment and location of the Carnotaurs using the video and motion tracking system has been an extreme worry that is shared by most members of park security. They can almost never be picked up on the motion trackers, and manual viewing of the video recordings is too painstaking for any member of the staff. If one were to escape, the costs for tracking it down would be enormous.

 

Characteristics: Similar to the t-rex in all respects, except for its size, red and tan color, and the fact that it has a single large horn on its snout.
Environment: Situated in the marshland or around shallow rivers, they were originally thought to reside in the plains, but a trial-and-error method of testing has shown that these animals have a far different lifestyle than paleontology suggested. See below.
Feeding: The Ceratosaurus was originally thought to be an active carnivore, hunting down large prey on the plains. It has surprised a few scientists that it does not run down and devour medium sized sauropods on the plains as previously believed. Ceratosaurus prefers more frequent feeding on smaller animals, heavily supplemented by large fish. The manner in which it catches these fish is quite entertaining to watch, as it tracks the movement of the fish underwater before lunging its head in to grab them. This takes at least ten or fifteen tries before it actually catches anything.
Habits: Solitary-hunters, the Ceratosaurus generally avoid their own kind. Only during mating season will they actively seek out a mate.
Ops Notes: Although most of their time is spent around and near water, the Ceratosaurs actually have a genetic flaw that causes their skin to swell up after prolonged exposure to water. It is believed to have something to do with a lack of oxygen, although testing continues.

 

Characteristics: Very bird-like in their build, and similar to the Mongolian Oviraptor in many respects, the Conchoraptor is an unusual animal just in its composure. Covered in sparse, white feathers, more so on its forearms, with a gray colored skin, and possesing a beak capable of crushing through some metals, the Conchoraptor is a truly unique animal.
Environment: These mysterious animals reside in the deep forest, where they live solitary lifestyles. They seem to possess extraordinary senses and can be almost impossible to track due to their silent movement.
Feeding: The Conchoraptor was originally a puzzle to paleontologists before any live ones were created. Its jaws suggested that it is a nut eater, or possibly an egg eater, but no one predicted that is was both of those, and more. Its diet consists of small rodents, lizards, eggs, berries, nuts, and very often, scavenged meat. This has made feeding the animals a very simple task.
Habits: The Conchoraptor has surprised many people by showing an unusually strong devotion to their offspring and mate. As soon as sexual maturity is reached, the male Conchoraptor will dig a deep burrow in the ground. This can sometimes be up to twelve feet below the surface. After finishing their burrow, the male lets out a string of mating calls that can go on for days if necessary. Many researchers have found these calls to be unsettling to listen to, especially at night. After a female has followed the source of the sound to the male's burrow, they mate. After mating, they are paired together for life, and the male leaves the female in order to consume as much food as possible. After the eggs are laid in the burrow, the female leaves, trusting that the male will come back to watch after her young while she is out feeding. This switch off happens once every two months, until the chicks are old enough to fend for themselves. Then the process starts over again.
Ops Notes: Lots of focus has been directed towards the maternal habits of the Conchoraptor. Their nesting cycle is extremely interesting to many scientists, especially those in the behavior and population control departments.

 

Characteristics: About the size of chickens, green, lizard-like and standing on their hind legs, Compsognathus are built for speed. Using their extremely flexible, almost prehensile tails for balance, and a lightweight design, compies can attain speeds of up to twenty miles an hour, surprising for their small size. Their jaws are lined with tiny, needle-sharp teeth, and they are capable of opening their jaws at a little less than ninety degrees. Their hands and feet are also extremely flexible, allowing them to latch on to any prey that is larger than themselves.
Environment: The Compy has seemed content to inhabit the plains and semi-arid areas, although some have been introduced into the marsh regions with varying degrees of success.
Feeding: Depends on the environment. Compys in the plains and semi-arid regions feast on a constantly-replenished supply of small lizards, while those who have remained in the marsh feed almost exclusively on insects, although they have reportedly made attempts at frogs and even a snake.
Habits: Comfortably solitary, the Compys will occasionally form loosely-knit herds when pursuing larger prey.
Ops Notes: Up to now, have demonstrated the least intelligence of any of the dinosaurs in Jurassic Park. There have been some reports of lost kittens in the Toluca Lake area. While there have been some whispered allegations concerning the Compys' complicity, no definitive link has been established.

 
 

Characteristics: Very similar to the Parasaurs, the Corythosaurus has a yellow and orange coloring and a domed crest on top of its head.
Environment: The Corythosaurus, to many people's dismay, has shown only to dwell in areas where the Parasaurs do.
Feeding: Plant-eater. This animal forages on all the same things as the Parasaurs do, with the addition of carefully plucking low-hanging fruit from trees and even showing preference to specific fruits.
Habits: After it was noted that the Corythosaurs seemed only to stay near the Parasaurolophus, some concern was expressed by the behavioral department for the reason of this. It was later discovered that the Corythosaurs practive parasitic nesting behavior, almost exactly similar to the Brown-headed Cowbirds of North America. The female Corythosaurus lays her single egg in the already built nest of the Parasaur. After hatching, the infant Corythosaur uses all of its energy to destroy the remaining Parasaur eggs, and if any have already hatched, it simply beats them to death using its egg horn. Then the mother Parasaur raises the Corythosaur hatchling as its own, until the process is repeated over again.
Ops Notes: Concern has been expressed over the parasitic nature of these animals, and the effect it will have on the Parasaur herd in the future. So far though, no noticeable effect has been noted.

 
 

Characteristics: Built on the basic carnivore pattern, with a heavy tail, strong limbs, and a long neck. Its ten-foot-tall body is colored dark green with white markings. Two broad curving crests run along the top of the head from the eyes to the nose, meeting in the center to make a V shape when viewed from the front. When aroused or disturbed, as well as when hunting, this deadly predator has two brightly colored, almost hypnotic fans on either side of its neck that coil out, making Dilophosaurus a beautiful but deadly addition to Jurassic Park.
Environment: The Dilophosaurs have demonstrated a propensity to roam wherever the hunt might take them, adapting with ease to (but rarely settling in) nearly any environment.
Feeding: Carnivore. The Dilophosaur was originally thought to be a scavenger, as its thin teeth and delicate head make traditional hunting impossible. But the creature surprised everyone with its ability to shoot a semi-toxic liquid, capable of stunning potential prey. The creature's deadly proficiency with its limber arms and legs, complete with razor-sharp claws, combined with a tendency to hunt in packs has transformed the Dilophosaurs into perhaps the Park's most efficient hunter of prey.
Habits: With few exceptions, the Dilophosaur are a tightly-knit herd, traveling in organized fashion. Recent field observations have suggested that the creatures participate in a complex culture, apparently abiding by a communal set of social manners whether resting, breeding or hunting.
Ops Notes: The emergence of the Dilophosaur as a cold and calculating hunter, capable of coordinating group attacks with surprising efficiency, has frightened more than a few people at InGen. [frill/poison/spitting abilities]

 

Characteristics: Small and agile, Drinker is a lightly built dinosaur about two feet tall and seven feet long, with an extremely sharp beak for plucking individual berries from the bushes.
Environment: Predominantly in the forest regions of the park.
Feeding: Drinkers are notoriously difficult for the park staff to feed, preferring low growing berries and bushes. Unfortunately, Drinker has to compete with local birds for their bushes and have to be hand fed imported berries which are often seasonal and difficult to acquire. Even more frustratingly, Drinkers will often stop eating a type of berry or plant entirely, making it necessary to find something different for them to be fed.
Habits: Always traveling in a herd, Drinkers will never be seen by themselves. They eat, sleep, reproduce, and nest together.
Ops Notes: It is not quite so important as it is entertaining to note that the Drinker almost always hops around on its hind legs in the manner of a kangaroo, rarely being seen practicing the typical walking locomotion of other theropods.

 

Characteristics: Gallimimus can almost be described exactly as a larger, featherless ostrich. Besides a slightly leathery skin, brownish coloring, and lacking a true beak, every other feature of this dinosaur is exactly the same as their flightless, African cousins.
Environment: Predominantly in the semi-arid region.
Feeding: The Gallimimus collects its meals - mostly small insects and worms - in an entertaining manner. Lacking in depth perception (the creature's eyes are fixed on either side of its head), the animal searches the ground for prey using its otherwise weak and useless arms. Upon discovering a potential meal, the Gallimimus proceeds to devour the entire area - including dirt and small rocks - with a ravenous appetite bordering on the comical.
Habits: Possessing decidedly less intelligence than most of its fellow dinosaurs, these creatures tend to live a very simple life. A typical day consists of combing the ground for prey (as described above) while avoiding predators with its tremendous speed.
Ops Notes: A mildly entertaining curiosity, the word around InGen is that the Gallimimus was chosen by Genetics as a practical joke. An extremely hyperactive and skittish creature, it's nearly impossible to approach one.

 

Characteristics: Classic example of a duck-billed dinosaur, with brown coloring and startlingly green eyes, these are probably one of the most recognized animals in the park because of their build.
Environment: Predominantly in the swamp region.
Feeding: Plant-eater. Paleontologists originally thought that this animal fed off of aquatic growing plants, but more recent scientific evidence suggested that it ate other types of plant matter. Well, in the end, older theories turned out to be correct. This animal will only feast off of aquatic plants and therefore rarely moves away from the swamps of Jurassic Park.
Habits: Other than dealing with their overly playful young, the Hadrosaurs lead a very dull life consisting of combing the surface of the water for food, sleeping in the shade around noon, and escaping from predators when the need arises.
Ops Notes:(no notes)

 

Characteristics: Small and fragile, the Heterodontosaurs stand on their hind legs most of the time, but occasionally revert to walking on all fours. The Heterodontosaurs have large tusks protruding from inside their mouths, used for sparring with other members of their species, and possibly as a defense mechanism. Having a slight beige underbelly, and a brown body, these animals blend in perfectly with the trees they usually can be seen resting in.
Environment: These animals were originally a huge puzzle to InGen scientists, who thought that the Heterodontosaurs would prefer the swamp region to any other, due to their small size and the abundance of food. However, almost immediately after placement in that area, they were observed migrating to the plains. Further observation showed them migrating to the forest at night, where they remained literally motionless lying on the ground. Testing has proven that their daytime is spent out on the plains, browsing and resting in the shade of tall trees, while at night, due to their poor eyesight, they retreat into the forest where they are less vulnerable to attack.
Feeding: The Heterodontosaurs were originally thought to be plant-eaters, but since they were introduced to Jurassic Park, scientists have observed them eating small rodents, lizards, frogs, and even more surprisingly, birds. Despite this wide variety of foods, their core diet consists of fruit and plant seeds.
Habits: These animals seem to base their whole life off of the need to reproduce. Yearlong breeders, they males are continuously fighting over the rite to mate with the healthiest female, sparring with each other using their long forward facing tusks. When not doing this, they can usually be seen roosting up in the trees, using their prehensile tails and grasping hands to remain motionless until they need to come down again.
Ops Notes: Some concern has been expressed over the population of these animals, as individuals are constantly being gored to death with their tusks during fights. Constant experimenting has still proven worthless to determine how to lessen the deaths of these animals.

 

Characteristics: Thirty feet long and ten feet high, the Maiasaura are beige-colored and have a long, duck-like bill on the end of their snout. They also walk around on their hind legs when relaxed, but when alarmed however, the Maiasaura get down on all four legs presumably so that they don't abandone their young during breeding season, although that theory has yet to be proven.
Environment: The Maiasaurs spend most of their time browsing in the forest and plains areas of the park, but during mating season, they migrate to the semi-arid regions where they have a better visual range and it is easier to guard their nests from attack.
Feeding: Plant-eater. Maiasaurs feed off of any plant matter within their reach, equally at home eating leaves from trees, bushes or grazing on grass.
Habits: The Maiasaura is one of the gentlest animals in the park, but the exact opposite can also be said about them during breeding season, when it is nearly impossible to get near one without causing alarm. It is during breeding season that the Maiasaurs form large nesting groups, each individual looking after not only their own, but other Maiasaur eggs. This group behavior is probably the reason for the sudden rise in their population since last year.
Ops Notes: (no notes)

 

Characteristics: A perfect example of the classic sauropod, Mamenchisaurus is similar in most aspects to the original Brontosaurus. With a long neck and tail, massive legs, and a huge ribcage, these animals are truly magnificent in their design. Brown in color, their teeth are peg-like and used for tearing the leaves off of low growing plants. Each leg sports a single large claw, possibly used for defense, although that behavior has not yet been observed.
Environment: The Mamenchisaurs can be found, to many people's surprise, in the forest regions of the park, occasionally coming out to socialize, reproduce, and escape hungry predators. These animals do surprisingly little damage to the environment when moving through the forest, as their narrow bodies can easily navigate between the trees.
Feeding: Plant-eater. Surprisingly, they do not feed from treetops as originally believed, but instead graze on low growing plants. The reason for this is described below.
Habits: Mamenchisaurs originally evolved their long neck, not to eat from the top of trees, as originally expected, but instead to counter-balance the weight of their enormous tails, which evolved as a defense mechanism. Another reason why the Mamenchisaur can't eat from the top of trees is because the sheer effort it would take to pump blood up to its head is simply impossible in a creature of this size, at least for extended periods of time. Another interesting thing to note is the symbiotic relationship between the Mamenchisaurs and Parasaurs. The Mamenchisaurs have learned that the Parasaurs always make a certain trumpeting sound when a possible source of danger has been sighted, and the Parasaurs stick near the Mamenchisaurs due to the fact that their long whip-like tails can safely protect both of the animals from attack.
Ops Notes: (no notes)

 

Characteristics: Able to walk on four legs, but spends most of its time on two, especially for running. Microceratops skin is rough and secretes a mild toxin that makes it undesirable as food for predators. In addition to this defense mechanism, the skin of these animals also contains chromatophores that allow them to slowly change their skin color amongst various shades of brown and green to better match their environment. The colors are based on the temperature of the surrounding environment.
Environment: Microceratops prefers to reside mostly in the forest and jungle, amongst heavy litter and undergrowth where its small size is an asset, as well as up in the tree branches. It is almost never seen out in the open.
Feeding: A vertical feeder, Microceratops consumes a variety of plant life. From low-growing plants, shoots and roots, to tree-borne fruits and mosses.
Habits: Highly territorial and fearless, Microceratops possesses a protolanguage of high pitched warbles and chirps which form a song that travels well over the treetops from one area to another. Study continues to determine how complex this song is and whether it differs by individual or region.
Ops Notes: Originally intended to be part of a "Jurassic Petting Zoo", these animals proved to be a disappointment in the entertainment department due to their extremely territorial nature. The first issue arose when the person handling the animals developed an extremely bad rash and was confined to his bed for three days. He later reported having a high fever and strange hallucinations. This was when scientists discovered that the animal was poisonous to the touch. The second issue was that the animal was constantly climbing up to the roof of the enclosure and shrieking loudly at anyone who came near it, even during feeding time. The "Jurassic Petting Zoo" was converted into a permanent enclosure for the creatures; however, numerous animals have since escaped.
[poison]

 

Characteristics: Possessing the longest name of any dinosaur, these small animals fill a niche at the smaller end of the herbivore list. Micropachycephalosaurus have been given the nickname ‘Pack Rats” due to the high pitched squeaking sound they make when frightened and the unusual flesh pockets in their throat, where they store scavenged grass seeds for later consumption. Their skin is smooth and colored greenish-brown with light flecks.
Environment: This animal populates mostly the plains and open grasslands, often mixing with much larger herbivores for protection while deftly avoiding being stepped on by their giant cousins.
Feeding: Micropachycephalosaurus will eat almost anything it can reach, from grass seeds, to nuts, grass blades and shoots.
Habits: Aside from storing grass seeds in its special skin pockets, Micropachycephalosaurs frequently scavenge the detritus from larger animals’ feeding. When large feeding Hadrosaurs or Sauropods move in to the tiny dinosaurs’ range, the ground underneath is covered with Micropachycelphalosaurs snatching up fallen leaves and edible vegetation.
Ops Notes: (no notes)

 

Characteristics: The size of a mouse with smooth, hairless skin and large eyes mounted high on its head. It is greenish-brown in color, and emits a squeking sound when aroused. Extremely oblivious to most threats, they can usually be identified by a small back poking up above the grass.
Environment: These animals reside only in the deep forest, where they are nearly impossible to track due to their small size. These small animals provide a challenge; both to keep track of and to maintain an accurate count due to their rapid reproduction. Their size allows them to slip in and out of the various paddocks as well as run loose in the residential areas.
Feeding: Plant-eater. This animal feeds on low growing shrubs, mosses, and berries.
Habits: The Mussaurus is a unique animal in that it is one of the smallest dinosaurs ever discovered. About the size of a large mouse, it can usually be found nesting near the base of a tree, or wandering through the bushes nearby. Even more incredible for an animal of this size is that it almost never tends to stay in one area, meaning that there are constantly tiny Mussauruses roaming around the park setting. It is nearly impossible to go out into the park, and not see one Mussaurus, as the animals are usually spaced one every fifty square feet.
Ops Notes: The Mussaurus population is not as fragile as one would guess due to their small and easily broken body, as they are yearlong breeders. This keeps the population at a constant level.

 

Characteristics: Standing on two legs, balanced with a long tail, and varying in color from dark-green to light-gray, Pachycephalosaurus stands approximately seven feet tall, and is near twelve feet long. Pachycephalosaurus also sports a massively thick, protruding forehead. Its domed-skull is decorated with a rim of small knobby horns.
Environment: The Pachys reside mainly on the plains, occasionally migrating to the semi-arid regions. No discernable cause has yet been observed for this behavior.
Feeding: Plant-eater. Feeds mainly off of ferns and mosses, although it is quite happy to eat whatever foliage is available.
Habits: The Pachycephalosaurs are possibly one of the most boring animals in the park to watch. Even though they display extremely thick head-gear, the Pachys almost never can be seen using it against either each other, or anything else for that matter, as it is used only as a defense mechanism, and the Pachys prefer to retreat into the jungle, rather than stand and fight. Another behavior exhibited by the Pachycephalosaurs, is the constant need to sleep, spending as much as 18 hours of the day resting in the shade.
Ops Notes: (no notes)

 

Characteristics: It's head is three feet long, made even longer by the long horned crest that extends backward high in the air. About twelve feet tall, and roughly the size of a large elephant, the Parasaur walks on four legs, occasionally switching to two for faster movement. A long, prehensile tongue in its mouth is capable of extending a foot straight out to grasp leaves just out of reach.
Environment: The Parasaur generally abides - per original estimates - in the forest region. It has, however, shown a remarkable adaptability and has migrated at times to the plains, semi-arid, and most recently, the swamp regions of the Park.
Feeding: Plant-eater. Content to feast on the ferns and foliage of the forest, although has demonstrated a new predilection for some of the water-based mosses in the swamp area.
Habits: The Parasaurs tend to group in herds, falling into a rigid social hierarchy. Males seem to achieve dominance in relation to the coloration of their skull crests with the more spectacularly-plumed Parasaurs adopting the leadership roles. Female social strata appear to be based on resonance of voice - the females capable of creating sounds at lower frequencies have repeatedly attracted the attention of the more brightly-colored males.
Ops Notes: Some concern over the Parasaurs' amazing adaptability. Several red flags have been raised over their highly-evolved ability to communicate with one another: while it's a bit premature to fear a Parasaur conspiracy, the beasts have demonstrated some rudimentary higher-level linguistic skills rivaling those of some monkeys. [linguistic skills]

 

Characteristics: Similar in most respects to Ceratosaurus, except with a narrower build and duller coloring, the Proceratosaur has been observed with both a tannish and a light grey color, used to blend in with its environment. Environment: Predominantly in the semi-arid region.
Feeding: Carnivore. Its diet consists mainly of the larger mammals found in the park, although it has shown a particular taste for the smaller herbivorous dinosaurs.
Habits: A rather uninteresting carnivore, the Proceratosaur is completely different from its Jurassic Cousin, in that it spends almost all of the day, from sunrise to sunset, chasing any small warm blooded animals that it sees, sometimes completely exhausting themselves after chasing one, until they simply collapse. It is of course necessary after a full day of chasing small animals to hydrate plenty, which is what the Proceratosaur does after waking up from its sound sleep. That is why the Proceratosaur can be seen one day out in the semi-arid regions, and the next day located right next to a river, avoiding predators and resting as much as it can.
Ops Notes: (no notes)

 

Characteristics: Purple-ish in color, and possesing an extremely sharp beak, the Psittacosaurus is roughly two meters long and a meter tall. Standing on its hind legs, Psittacosaurus is possibly one of the most primitive forms of ceratopsian, although recent finds may disprove that theory.
Environment: These beasts prefer the forest where edible foliage is abundant. The nearby T-Rex, however, has sent many a skittish Psittacosaurus running for the semi-arid areas.
Feeding: These vegetarians make ample use of their powerful beaks, feasting on whatever foliage is available.
Habits: Harmless and guileless, these geriatric-looking beasts come closer to actual friendliness than any other dinosaur in the park. While nervous around the other animals, they have taken quite an affinity to people, often approaching the boats.
Ops Notes: While more interesting dinosaurs have since been created, these early efforts have proven their staying power, consistently remaining one of the favorite attractions in the Ride. One InGen rumor directly attributes their continued survival to their charisma. According to legend, Hammond was considering "pulling the plug" on the Psittacosaurus until he caught wind of their popularity.

 

Characteristics: Similar to the Anurognathus, the Pteranodon has a thicker build, stronger legs for lifting heavier prey, and a long, narrow beak filled with needle-sharp teeth. Protruding from the back of its head is a long crest, possibly used as a mating display, although recent studies have shown that there may be more reasons for having this crest than originally thought.
Environment: The Pteranodons reside in an aviary located at Thunder Canyon, with a deep river at the bottom connected via subsurface caves to the open ocean which supplies the river with fish. No efforts have been made to place the Pteranodon in any other sections of the park, due to their highly aggressive nature.
Feeding: The Pteronadons were originally thought to be fish eaters, but the variant resurrected by Jurassic Park scientists has teeth and occasionally supplements its diet with larger food. Cows are sometimes released in to the habitat to vary their diet though it still consists primarily of fish.
Habits: Some concern has been expressed over the apparent danger level of the pteranodons in the park. Able to comfortably lift 150 Lbs. just with their talons, and with a mouth filled with needle-sharp teeth, the pteranodon is without a doubt one of the most terrifying animals in the park. While some scientists tend to spend all their time studying the Pteranodons, most others will try to stay away from the aviary as much as possible. Aggressiveness is the one factor about the Pteranodons that make them so frightning. If there is any intruder in their cage larger than a sparrow, the Pteranodon will dive from the top of the aviary at full speed, and crush the animal or person beneath its weight. Also possesing no chewing or swallowing mechanism, the Pteranodon simply pecks at large prey until its size is small enough for the Pteranodon to have slide down its throat.
Ops Notes: Seemingly a new species of Pteranodon, these particular ones have not yet been named. They posses teeth, unlike their fossilized counterparts, and are carion eaters as well as fish eaters. [aggressiveness]

 

Characteristics: Similar to modern day crocodiles, the Sarcosuchus is fourty feet long, and has a six foot long snout. It's color is light brown.
Environment: Sarchosuchus is confined to a lake in the Northern portion of the island.
Feeding: (See the feeding habits of modern day crocodilians. All apply)
Habits: Usually can be found patrolling the murky waters of its home lake.
Ops Notes: Extreme aggressiveness has made dealing with this animal very difficult. It is usually observed and fed through remote procedures, as no one want to get near enough to the water's edge in order to see it.

 


Characteristics: Small and agile, the Segisaurus is similar in physiology to the Compsognathus, although it is slightly larger, and is grayer in color.
Environment: Predominantly found in the island's higher elevations, Segisaurus' agility, sense of balance and powerful legs serves it equally well when it periodically migrates to lower, more arid regions
Feeding: Carnivore. Its diet consists primarily of small mammals and lizards, although it has occasionally gone after cat-sized possums and birds.
Habits: Similar to the Compsognathus, it lives a solitary lifestyle until breeding season comes. Then large groups of Segisaurs can be seen darting in and out of the rocky formations in the north, eating excessive amounts of food, and laying their eggs in the large spaces between rocks.
Ops Notes: (no notes)

 

Characteristics: Forty feet long, green colored, with a huge bulky body and two rows of vertical armor plates along its back. The tail has four, three foot spikes placed on it for defense. With front legs that are larger than the back ones, and an absurdly small head, Stegosaurus is perhaps one of the dumbest looking animal in the park. But, looks aside it is actually one of the more intelligent animals, capable of telling the difference between many plants so as not to poison itself.)
Environment: The Stegosaurus resides in the plains and forest regions of the park.
Feeding: Voracious eaters, the Stegosaurs feed on whatever foliage is available, giving them a highly nomadic lifestyle.
Habits: Extremely protective of their infants during breeding season, the Stegosaurs are generally peaceful animals; casually walking up to any animal that can not be identified as a threat. All other times it can usually be seen grazing or drinking.
Ops Notes: Smarter than their apppearance would suggest, the stegosaur is an expert at determining which foods are edible and which aren't just by looking at them. The discerning factors are still unkown.

 

Characteristics: The size and grayis-brown color of an elephant, with the truculent stance of a rhino. The horns above each eye curve five feet into the air, looking almost like inverted elephant tusks. A third, rhino-like horn is located near the nose, and they have the beaky snout of a rhino. Triceratops also have a fan-shaped crest behind their heads that's made of solid bone, and it's very strong. One animal weighs about seven tons, and they're approximately thirty feet long.
Environment: Creating a suitable habitat for the Triceratops has turned out to be more difficult than originally anticipated. The most successful colonies currently reside in the plains and semi-arid regions.
Feeding: Much of the difficulty in acclimating the Triceratops to the Jurassic Park environment is directly caused by the creature's specific food needs. While a strict herbivore, the Triceratops' elongated teeth, while extremely sharp, have proven to be less than suitable for chewing ordinary leafy plants. While palm fronds gathered by Rangers have sustained the creatures so far, there is much concern over finding a more consistent source of nutrition for these hearty eaters.
Habits: The attempt to understand the Triceratops' social behavior has resulted in a sort of paradox. While preferring the company of others of its kind, the creatures generally spend a great deal of time fighting among themselves, sparring with their trademark horns.
Ops Notes: Let there be no doubt about it: the Triceratops is Hammond's favorite inhabitant of the Park. With classic features familiar to nearly everyone and a propensity to brawl with one another in spectacular fashion, the Triceratops is a huge crowd-pleaser. Hammond has demonstrated an unwavering belief in the creatures' marketability, lending a deaf ear to complaints over the difficulties of sustaining the increasing population.

 

Characteristics: Similar to the larger raptors, it has an extremely narrow snout, presumably for burrowing, but no behavior has been observed to suggest this. Grayish in color, they are about the size of a small dog. Environment: There have been occasional sightings in the swamp and marshland areas of the park, however, these sightings were very few, and they are now though to reside predominantly in the forest regions. This has proved difficult for InGen scientists to study the animals, as they run away at the site of any larger animal. One team set up camp in the forest, hoping to learn more about their mysterious behavior, and reported that the Troodons seemed to be playing a game of cat-and-mouse with the scientist, darting out of bushes and running across the clearing as fast as they could to the other side. Due to their nature, very little is known about these highly intelligent creatures.
Feeding: Carnivore. Eats whatever small sized prey is available.
Habits:
Ops Notes: Possibly the most intelligent dinosaurs in the park, extreme concern has been expressed by more than a few InGen workers. Possibly even more intelligent than the Raptors of the park, testing continues to determine if it poses a threat.

Characteristics: With an enormous square head, five feet long and massive seven inch teeth, placed on a muscular neck, Tyrannosaurus is designed for slicing into meat and biting through bone. Capable of speeds up to thirty miles an hour, with a heavily muscled tail, human-sized fore-arms and massive legs, Tyrannosaurus is easily one of the most massive and impressive predators in the park. Environment: The original plan was to insert the T-Rex in the plains and semi-arid regions, as the Park's designers hoped to impress crowds with its dazzling hunting abilities. The beast has proven to be a bit of a disappointment in the showmanship department, however, tending to conceal itself in the forest.
Feeding: Adding to this disappointment is the realization that, when able, the carnivorous T-Rex prefers to scavenge the remains of dead meat rather than hunting for fresh prey.
Habits: Despite all the trappings, the T-Rex has repeatedly demonstrated a kindly nature. Seemingly content to dine on carcasses in the quiet seclusion of the forest, the T-Rex has turned out to be Jurassic Park's unlikely model citizen.
Ops Notes: While the T-Rex has failed to live up to its original (and overly optimistic) expectations, the Genetics Division maintains high hopes of effecting a serious attitude adjustment. Recent efforts have concentrated on increasing the creature's visibility.

Characteristics: Approximately two meters high and colored dark brown. The head is two feet long. From a pointed snout, a long row of teeth run back to the hole of the auditory meatus which serves as an ear. Its skin is leathery, with a pebbled texture, strongly muscled legs and fore-arms, and a long, ridged tail used for balance. Each foot is equipped with a six inch retractable claw on the inside toe, used for taking down prey. All in all, a perfect killing machine.
Environment: Due to its violent nature, the Raptor has been confined to its own pen, composed of grassy plains and a small lake.
Feeding: While the Raptor will eat almost any meat, it seems to prefer fresh kill. The live cows that are occasionally released into the pen invariably meet the same fate. After being cornered by a coordinated attack, the hapless cow is generally gripped by the Raptors' long fingers, slashed open by a the razor-sharp, sickle-shaped claws adorning the Raptors' feet, then gnawed to death by the creatures' abundant teeth.
Habits: Crafty and cunning, these creatures are killing machines. While their apparent intelligence is perhaps overrated, there's little doubt that these creatures cooperate together out of a single, common desire: the love of the hunt.
Ops Notes: One of the Park's biggest surprises, no one - including Hammond - seems to know what to do with the cunning Raptor. Until some final decision can be reached, the creature remains segregated from the other dinosaurs in its own pen. The Raptor has proven to be of great interest to the scientists in Genetics, whose numerous experiments upon the creature reflect a desire to learn more about its dark motivations.
