Allosaurus fragilis Length: 40 feet Height: 14 feet Weight: 2 tons (male), 2.5 tons (female) Coloration: Male - A vibrant red with black stripes along the back. Female - A less prominent red or even maroon, still with the stripes. Juveniles - Light brown with thinner versions of the stripes. Diet: Small to medium-sized prey, such as ornithopods and Stegosaurus. Packs are able to tackle young or weak sauropods, commonly Apatosaurus. Preferred Habitat: Sparse forests and open grassland. It is the need for open space to enable Allosaurus to run after its prey that this dinosaur does not inhabit the more densely forested areas of Sorna. Social Structure: Allosaurus males and sub-adults of either sex are nomadic and may form small hunting packs. Such packs will often trail after migrating sauropod herds, waiting to take out the young or weak members that stray too far from the security of healthy adults. Allosaurus packs do not exhibit complex pack structure and hierarchy, although largest individuals tend to dominate over smaller ones. Packs can stay together for decent periods of time as long as food is plentiful. Mature females tend to be more territorial and prefer to live alone, although it is not unheard of for adult females to display packing behavior. Description: Large bipedal carnivore. Slightly smaller than Tyrannosaurus, although not as robust and more lightweight. Sleek anatomy promotes speed and agility, top speed 50 mph for short distances. Front limbs long and well-muscled, with grasping three-fingered hands tipped with eagle-like talons, used for maiming prey. Paired crests over each eye, larger in males and absent in juveniles. Females larger and more robust than males. Behaviors: Allosaurus is an active hunter, capable of taking down prey many times its own size. Its head is not as strong or robust as that of Tyrannosaurus and its bite force is weak compared to its body size. The jaws cannot hold onto struggling prey or crush bone, but they can open extremely wide. Hunting Allosaurus will run up to their prey, then use their upper jaw like an axe to hack and slash at the victim before backing away; repeating the process to weaken the victim until it dies of bloodloss. Allosaurus can be reckless, especially when hunting in a pack. Broken bones are a common occurrence, however Allosaurus is surprisingly tough and durable, able to survive injuries that would kill other animals. Allosaurus has a very distinct call, sounding like the blast of a trumpet mixed with the roar of a lion. A receptive female will typically call out to invite males into her territory. Males seeking out females are often forced to compete with other males and extremely vicious fights can occur. Female Allosaurus are larger than males, and highly aggressive. They are also very fussy and may attack unsuitable males without warning. A male will approach with caution; showing off his eye crests to the female in attempt to impress her. If the male is successful, he will make a hasty exit as soon as mating is over. The Allosaurus female will lay her eggs in a mound constructed of loose dirt, similarly to the nests of crocodiles. When she hears her young squeaking, she will help free them by carefully digging them out of the mound with her talons. Females are attentive mothers, guarding their young and bringing them food until they are old enough to look after themselves. Depending on the disposition of the female, she may allow her young to remain with her into sub-adulthood and possibly even adulthood, thus forming familial packs (more common when prey is abundant). More aggressive females will have a tendency to attack and eat her offspring as soon as the maternal bond is severed. Allosaurus males and sub adults of either sex are nomadic. Small packs will often trail a migrating sauropod herd waiting to take out young or weak members that stray too far from the security of healthy adults. These packs do not exhibit complex pack structure and hierarchy, although largest individuals tend to dominate over smaller ones. Packing between males is much more common than in females, and the pack can stay together for decent periods of time if food is available. Baryonyx walkeri Length: 40 feet Height: 15 feet Weight: 3 tons Coloration: Male - green mottling, with dark green blotches on the back and a pale yellow underbelly. Female - brown with paler underbelly. Juveniles - a lighter version of the adult female. Diet: Mostly fish and other aquatic prey. In times of need smaller dinosaurs, including Othnielia and juvenile Parasaurolophus, are usually the easiest prey. Preferred Habitat: While it still prefers to live near rivers, lakes, or coasts. Social Structure: Either solitary or in pairs. Like grizzly bears, several individuals may congregate near water sources where fish is plentiful. The largest and most powerful adults claim the most fruitful fishing spots and individuals (most often the males) will sometimes fight over the rights to prime fishing spots. Description: Large bipedal carnivore. Baryonyx is the smaller relative of the gigantic Spinosaurus on Sorna. Similarly to Spinosaurus, Baryonyx is well-adapted as a fish-eater, using its long, crocodile-like jaws or its large, hook-like thumb claws to spear fish and other aquatic prey straight out of the water. Its pointed, conical teeth - as opposed to the curved, serrated teeth of other carnivores - are perfect for maintaining a hold onto slippery prey. Breeding Season: Wet season, when water levels are at their highest and prey is more abundant. Behaviors: Baryonyx was once considered to be a relatively docile theropod. Not particularly territorial, males tended to avoid conflict with one another unless fighting over females during the breeding season, while females were only fierce in defense of their young. Otherwise, individuals of both sexes preferred to avoid confrontation. When rival males challenge resident males for their territories, violent clashes break out. The heavy claws, used for spearing fish and killing small prey, also make for deadly weapons that can inflict serious wounds during fights. Baryonyx is a patient animal, and will often stand for many hours over water, poised statue-like with opened jaws partially submerged, waiting for a fish to swim by. Upon sensing the vibrations of a passing fish, Baryonyx will snatch it in its jaws and toss it onto the ground, using its claws to pin the slippery prey while its teeth rips away flesh. Baryonyx may also use its claws to smack fish clear out of the water. During the wet season when there is usually a glut of fish, Baryonyx may eat only the most nutritious parts of its catch (including the eggs and head) and then indifferently leave the rest of the carcass to scavengers. During the dry season when fish stocks are at their lowest, Baryonyx sometimes have been known to follow Metriacanthosaurus over extensive periods of time in order to steal their kills. The intense heat of the dry season often renders Metriacanthosaurus sluggish and lethargic, giving Baryonyx the opportunity to scavenge their kills without being harassed. Despite the potential for aggression between carnivores, Baryonyx has a somewhat symbiotic relationship with Proceratosaurus. Proceratosaurus can often be seen trailing after Baryonyx in the hopes of scavenging from the carcasses the larger carnivores leave behind. The Baryonyx benefits from the Proceratosaurus' presence in that the smaller dinosaur is more adept at detecting danger. So to keep them around, Baryonyx encourages Proceratosaurus by allowing them access to any leftover meals. This relationship still continues in spite of Baryonyx now having little to fear, and as a result Proceratosaurus is the only species which is tolerated by the Baryonyx and is thus safe from other predators which may attempt to hunt it, such as Metriacanthosaurus and Velociraptor. Unable to run fast, when seeking prey on land Baryonyx is an ambush hunter which quietly stalks its victims. It typically targets the young or infirm animals from Parasaurolophus herds, but it may also stalk Gallimimus groups as well. When hunting, Baryonyx will attempt several mock-charges to break the herd apart so the slower-moving, vulnerable individuals are revealed. Baryonyx then uses a final burst of speed to throw itself at its target, pinning it to the ground and then tearing it apart with its enlarged claws, eating it alive. It may also swipe at prey in order to stun it enough to knock it over for consumption. In addition, Baryonyx often searches for burrows. Upon finding a burrow which may harbor prey, Baryonyx will collapse the burrow with its weight, before using its massive thumb talon to hook the prey out. The Segisaurus' venomous bite is usually avoided after the animal is crushed by the collapsing of its burrow. The female builds her nest close to water. Once the eggs are laid and construction of the mound is completed, both parents will retreat to deep water, always on guard should anything threaten the nest. Both parents will fast until the eggs hatch, not actively hunting so their energies are focused on protecting the nest. When she hears her young squeaking, the female digs them out, and like ducklings, they will follow her wherever she goes, riding on her back when she is swimming. While the male may linger for a while, he will usually lose interest early on in the chick's lives, leaving them under the protection of their mother. This is probably for the best, as males have been known to consume infant Baryonyx, risking the wrath of a furious mother. The mother Baryonyx hunts for prey either in water or on land, and she will share her catch with her offspring. Over time, she will gradually become more resistant to her young until the day comes when she will refuse to let them take their share of the food. Having watched their mother hunt many times before, the young are forced to put their skills to use or else starve. The female will still watch over them, but she will no longer feed or interact with them, becoming more detached the older her offspring become. When her young have grown adept enough at fending for themselves, they go their own way in life, seeking mates and territories of their own. Baryonyx's forelimbs are so long, the animal is capable of standing on all fours. It may adopt this position over water when waiting for a fish to swim by, or use the stance to submit to more dominant individuals. It hardly ever walks on all fours as it risks blunting its claws. Baryonyx is a fantastic swimmer, and is has even been known to sleep underwater. When at rest the dinosaur can remain submerged for up to 20 minutes, surfacing to take a breath even when not fully awake. Carnotaurus sastrei “chamaeleo Length: 25 feet Height: 8 feet Weight: 1 ton Coloration: Adults - Base color is a chalky white. Individual Carnotaurus are known to have one other base coloration they are most comfortable with, this taking the place of the usual individual variations of color in other dinosaurs. Adults are capable of triggering a mechanism which causes them to blend in with their immediate environment. They are also capable of mimicking other animals' color patterns; or flashing their skin vibrant colors with its mood or as a defense mechanism to ward off adversaries. Juveniles - Like the adults, the base color of juveniles is also a chalky gray or white, although juveniles lack the necessary brain pathways to achieve full control of their color-changing abilities. They can only display rudimentary color-changing, such as changing their colors based upon their mood. More sophisticated abilities are adopted with age. Diet: Animals smaller than itself; carrion. Preferred Habitat: A Carnotaurus' preferred habitat is anywhere there is sufficient shade so that the dancing sunlight patterns do not leave trails on its skin and reveal its presence. Densely forested areas and abandoned human facilities are perfect for this purpose. Social Structure: Typically found in groups of 2 or 3 animals with an alpha individual that can be either male or female. Some packs are territorial, others are nomadic. Description: Medium bipedal carnivore. Bull-like horns protruding over each eye, larger in males and mere stubs in juveniles. Relatively small head in comparison to its body, short snout. Forelimbs no more than stubs. Stocky build and robust anatomy. Skin is thick with several rows of bumps running down its back and tail. Unique ability to change its skin color at an amazing speed, similarly to a chameleon or a cuttlefish. Behaviors: Along with its useless forelimbs, Carnotaurus has a rather weak bite in relation to its body size. Its advantage lies in its unique ability to change its color to match its environment; enabling it to blend in so well with its surroundings that it can appear practically invisible unless it makes a sudden movement. Carnotaurus uses this advanced color-shifting ability to camouflage itself perfectly, allowing it to get as close to its prey as possible - this behavior is known as 'cloaking'. Once close enough to its quarry, Carnotaurus will charge suddenly at its prey, knocking the victim down with its reinforced skull and stamping on it until the victim is rendered dead or unconscious. While its bite is weak, Carnotaurus' skull is strong, and once it has its prey subdued the Carnotautus will deliver repeated blows with its horns before consuming the battered mess. Carnotaurus is incapable of maintaining its camouflage while running at high speed, but it is an incredibly patient animal. It has been known to stalk its prey for many an hour while cloaked, approaching slowly and cautiously before making the final charge. This hunting method is incredibly effective and many hunts end with a kill. As well as hunting, Carnotaurus also uses its color-changing ability to express emotions. Confusion and shock are conveyed by a chalky white - its base color - and ripples of color are used during mating rituals; to express anger or upset; and to intimidate other predators. Similar-sized predators such as Ceratosaurus and Metriacanthosaurus tend to find the Carnotaurus’ ability to turn invisible at will very unsettling, so they will usually try to avoid the areas where a Carnotaurus is likely to be present. Some Carnotaurus may be found living near packs of Velociraptor, as both species occupy similar habitats. This can cause tension between the two species, although sometimes a territorial truce is made as the far more intelligent Velociraptor take advantage of the fact other medium-sized predators avoid wherever there may be a Carnotaurus living nearby. In turn, the Carnotaurus benefit from the pack's leftover kills; its tough skin providing some protection against the claws and teeth of its aggressive contemporaries. When attempting to impress a female, the male Carnotaurus will perform a mating dance, crouching and swaying his body from side to side, flashing ripples of vibrant color through his skin. Females will visit each male’s personal “dance spot” and choose the largest male with the best dance, the largest horns, and the most vibrant colors. Carnotaurus prefers to avoid conflict with its own kind - disputes between competing males are more commonly resolved with color-flashing and roaring rather than physical force. In extreme circumstances, males will fight, using their horns to butt one another into submission. The mother Carnotaurus will not eat while she is guarding her eggs. Once they hatch, however, the young are forced to fend for themselves. Learning to cloak itself in accordance to its environment is essential for a young Carnotaur’s survival. Carnotaurus is most active during dawn and dusk. A camouflaged Carnotaurus in a well-shaded environment is virtually impossible to spot. Being so elusive, this dinosaur is more often heard than seen. It has a distinctive, gurgling roar, unlike that of any other dinosaur on Sorna. Coelurus Compsognathus “triassicus” Compsognathus “triassicus” Length: 3 feet Height: 1 foot Weight: 6 pounds Coloration: Adults - a bright green mottling with darker green back striping. Juveniles - a light brown that gains green pigmentation later in life. Diet: Primarily lizards, small mammals and invertebrates, although swarms are capable of taking down much larger prey, usually dinosaurs the size of a Dryosaurus. Compies are also opportunistic scavengers and will consume dung and carrion. In fact compies were bred initially to function as a form of waste disposal for Jurassic Park on Isla Nublar - since the extinction of prehistoric bacteria which broke down sauropod (and other large herbivorous dinosaur) dung, many compies were produced to help keep the island clean as compy dung is small and easily broken down by modern bacteria. Preferred Habitat: These tiny dinosaurs can be found all over Sorna and Nublar although they prefer any habitat that has sufficient cover where they can hide, such as long grass or thick undergrowth. Compies can often be found in abundance near the regularly-used latrine sites of Corythosaurus and Parasaurolophus, coming out to feast on the excrement these large hadrosaurs leave behind. Social Structure: Social dinosaurs, preferred group size range from two individuals to up to 20. Description: Small venomous bipedal carnivore, the second smallest dinosaur cloned by InGen. Sleek body, long neck, tail and legs, two fingers on each hand. Jaws are narrow, filled with many sharp, pointed teeth. Eyes large. Despite its "cute" appearance, compies are in fact highly aggressive and will not hesitate to bite on contact if it is hungry or feels threatened. Breeding Season: Individuals/ clans breed all year round, although flocks are more likely to breed when wet season boosts vegetation cover and food supply. Behaviors: As well as being the smallest species of dinosaur on Sorna, Compsognathus is also one of the most abundant thanks to its high birth and fast growth rates. Each individual in a swarm emits a pungent pheromone which fuel their adrenaline levels, causing them to act erratic and violent as well as to appear fearless and inquisitive in the presence of larger creatures, often being so bold as to steal strips of meat from the kills of bigger carnivores. Lone compies behave much like other small carnivores - timid and skittish. This is due to the lack of pheromones being produced by others in a swarm. When alone for too long, females may become stressed and release infertile eggs involuntarily. Compsognathus mating and chick-rearing habits are vastly different depending on whether the mated pair is solitary or a part of a much larger group. A mated pair of Compsognathus without a flock is far more dedicated to one another than a mated pair living within a flock; and they also remain together for longer. A lone male will attempt to secure a mate by performing an elaborate, high-energy dance, whereby he will perform a series of hops, leaps and flips to allow the female to assess his physical fitness. If receptive, the female will respond by circling the male, rubbing her body against his before allowing him to mount. Following the coupling, the male will engage in ritual feeding behavior and even help to locate a safe place in which the female can lay her eggs. When the eggs hatch, both parents take care of the young, and upon reaching adulthood they are not forced to leave their parents like many other dinosaur species. As the lead pair continue to reproduce, their adult offspring are also seeking mates and producing offspring of their own. As a result these familial “clans” continue to expand, eventually forming the great flocks for which this dinosaur is known. After several generations, mate dedication becomes a thing of the past as reproduction becomes a much more maddening affair. This is due to the high levels of adrenaline-producing pheromones and the increasing competition within the flock. Vicious fights between males over females and squabbles between females over the best males will occur, with males flitting from female to female in a rush to fertilize as many as possible before their rivals. As a result, inbreeding becomes a common occurrence, and compies living in a flock, while happier in general, often have poorer health owing to the high possibility of their parents being closely related. Eggs are usually laid within a burrow underground, a hollow in a tree, in dense thickets or deep inside the forgotten reaches of human structures. Lone parents take a lot of time and care to look after their first brood, thus helping to form the bonds that will remain for the rest of their lives. As their numbers continue to grow, laying and chick-rearing become far more chaotic. Flock Compsognathus nest communally, in which many hastily-built nests all tightly clumped together in a small space. The eggs are incubated by anyone within the flock, not necessarily by their own parents. The chicks are capable of running around and hunting with the adults of the flock within days of hatching, and the sheer number of juveniles produced means that at least a few do manage to survive and produce offspring of their own. Compsognathus produces a mild venom from glands in the lower jaw. A compy's strong jaws lock onto the victim and the venom is injected into the bloodstream via its small teeth, similar in fashion to a Gila monster. Although a single bite would not do an adult human much harm, in high doses the venom has a calming effect, preventing the victim from struggling as the compy swarm begins to eat the prey even while it is still alive. Like an army of ants, flocks of compies patrol the jungle floor, eating anything in their way from insects to small dinosaurs, devouring them alive in a piranha-like fashion. Compsognathus bites also have the potential to pass on severe infections due to the bacteria in the animal's jaws, which it gains from the dung and rotting carrion it eats. Fast and intelligent, Compsognathus is active both day and night thanks to its large eyes and sharp eyesight. Like Velociraptors, Compsognathus is very vocal and communicate with others using a variety of squeaks, whistles and chirps. Unlike raptor packs, Compsognathus flocks appear to have no real hierarchy, although one or a few individuals may appear more dominant over the group. This is usually the eldest mated pair within the flock, or their eldest offspring/ descendants. Wherever they go, the rest will follow. Deinonychus Dilophosaurus “venenifer” Length: 22 feet Height: 10 feet Weight: 400 pounds Coloration: Male - an olive green, with darker green (sometimes black) blotches and some white striping on the body and crests, and a red and yellow mottled frill. Female & Juveniles - like the male, only a more drab green and paler markings. Diet: Meat, from lizards to small ornithopods. Prefers fresh meat over carrion. Preferred Habitat: Heavily forested terrain near a water source. Social Structure: Dilophosaurus is a pack-dwelling species. The male offspring are chased from their natal packs a few weeks prior to the females, and each gender forms small same-sexed packs. Upon reaching breeding age, the male "bachelor" packs will purposely seek out these female packs, whereby they will mix as they form mating pairs. Being patriarchal in society a male will establish himself as dominant over his brothers, and he will choose the strongest, most assertive female as his mate. It is the males which actively fight rivaling males which may try to steal the females away. Description: Bipedal carnivore. Pair of semi-circular crests on top of the head. Large frill of vibrantly-colored skin which usually lies folded back against its head and neck, capable of fanning out and vibrating when the animal is angered, scared, or playful. Breeding Season: Wet season, as the rivers and bodies of water are an important part of their mating rituals. Behaviors: Dilophosaurus is an elusive and nocturnal dinosaur. It is a recognizable animal, sporting a pair of semi-circular crests on top of its head. Individuals use these for display or communication, with elaborate head-bobbing accompanied by hooting calls. Another spectacular feature of this dinosaur is its frill of membranous skin that can be expanded like a cobra's hood around its neck. The frill is vibrantly colored, especially in males, and can be used to 'hypnotize' prey, or to warn off enemies before delivering a bite or spitting. The frill is capable of being vibrated, making a loud rattling sound. Also known as the "spitter", Dilophosaurus gets its nickname from its ability to spray a thick, black gooey substance at its victim to a distance of up to 20 feet. This substance has the odor and texture of vomit and it is possible the dinosaur mixes powerful acids from its stomach with venom produced from its venom ducts prior to release. The substance causes burning of the skin and immediate blindness if delivered to the eyes. Dilophosaurus' venomous saliva allows the animal to take down much larger prey than its teeth and claws would otherwise allow. As well as spitting, Dilophosaurus can also inoculate its venom by biting prey and then releasing, waiting for the victim to die, similar in fashion to a Komodo Dragon. Once entered into the bloodstream, the venom causes extreme pain and eventual paralysis. Juveniles and sub-adults are very playful and inquisitive, often playfully torturing their prey before killing it, while adults are usually more reserved and direct in their hunting strategies. Courtship in Dilophosaurus is rather elaborate in comparison to other dinosaurs on Isla Sorna. Taking place near a body of fresh water such as a river or stream, a male and female Dilophosaurus pair will first take turns to drink water then hoot and snarl at each other. This process can last for several hours. Following this, the male will initiate a mating dance to reel the female in. The male stands to his full height, tilting his head back to extend his frill a little way to allow the female to get a good look at the bright splodges of color. The male moves around the female in a circular pattern, bobbing his head to display the crests atop his head. If receptive, the female will follow his steps, bobbing her head in time with the male, mirroring his movements. The dance ends with the two dilophosaurs poised side by side, necks taut and heads tilted skyward. Mating occurs immediately afterwards, and more matings may occur within the next few days without the mating ritual beforehand. When the next time for breeding comes round, the same pair will perform the same ritual to renew the bonds between them. Dilophosaurus pairs mate for life, and both parents aid in nest construction, egg incubation and chick rearing. However if the female happens to die, her mate may either attempt to steal a female from one of his brothers, or leave the pack to search for a new mate elsewhere. If it is the female which is left mateless, she typically remains so unless a new male tries to court her. Being more attached to her sisters, a female is more likely to remain with her pack rather than leave it, even if it means never reproducing again. Individuals in a pack communicate by making a variety of hooting, whistling and squeaking sounds. When aggressive, Dilophosaurus produces a hissing scream which, in combination with the rattling frill, can be particularly deafening. "Metriacanthosaurus" shangyouensis Length: 32 feet Height: 10 feet Weight: 1.8 tons Coloration: Male - A distinct blue color, with broad triangular white stripes, white underbellies, and red heads. Female & Juveniles - Like the male, only without the red head. Diet: Scavenger and predator of small to medium-sized animals. Preferred Habitat: Dense forest and jungle. Social Structure: Pairs and small groups. Description: Medium-sized bipedal carnivore. Metriacanthosaurus has slightly elongated vertebrae spines which form a small ridge along its back, making it appear rather humpbacked. This, unlike Spinosaurus or Ouranosaurus, is an attachment for muscles; reinforcing the skeleton and adding to its overall power. Pound for pound, Metriacanthosaurus is the most muscular dinosaur on Sorna. Behaviors: Metriacanthosaurus are selectively violent to the point of seeming evilness. They view smaller carnivores as direct competition and will often go out of their way to eliminate any potential threats to their prey, young, or hunting grounds with extreme prejudice. Due to this adaptation, these carnivores have an immense dislike for carnivorous species smaller than itself, especially pack hunting raptors whom they see as potential threats. Thus, Metriacanthosaurs will target Raptor packs with near never ending vigor, much more so than other predators, some even seeming to fly into a rage at a raptor's very scent. Using their thick hide, which easily deflects and dulls the ability to a raptor's iconic claws to do any real damage without sufficient time and immense strength, these medium sized carnivores attack without hesitation or fear of serious injury when the opportunity presents itself to eliminate a Raptor. Dilophosaurus and other venomous species are not safe from the blatant hatred of Metriacanthosaurs either. Much like the predator’s thick hide helps to protect it from slashing claws and teeth, a slight immunity to low doses of venom is also present. Though numerous bites or direct blasts to the eyes can still be potent, Metriacanthosaurs do benefit from their strong immune systems when confronting Dilophosaurus. Metriacanthosaurus is very particular to heat and does not do very well in droughts or heat waves. It is generally more active at dusk, night and dawn when it is cooler and during the day it rarely moves, instead taking up residence in shady patches or even resting in water with just its nostrils visible above the surface. Metriacanthosaurus roars sound similar to the mating calls of crocodiles and alligators although much higher in pitched. Metriacanthosaurus does not hold a territory of any sort as it is nomadic and never stays in the same place for very long. It buries its dung to hide its scent from the larger carnivores as it is incredibly fearful of dinosaurs the size of Tyrannosaurus, despite its brutish nature toward smaller and equally sized creatures. Additional Notes: This species is actually Yangchuanosaurus which was believed to be a species of Metriacanthosaurus at the time of its cloning by InGen. Segisaurus halli Length: 4 feet Height: 2 feet Weight: 30lbs Coloration: Adults - Brown bodies with yellower undersides for the body. The head, neck, and the upper neck are a base dark blue, with yellow outlining the features of the head and going down the neck and body in a set of stripes. Faint white stripes sit on the arms, their purpose unknown. Juveniles - Similar to the adults, without the striping features. Their darker camouflage allows them to hide easier from predators and prey, and allows for better ambushing. Diet: Lone individuals tend to prey on smaller animals, such as Compsognathus, lizards, rats, insects, and the more native fauna of the island. When in small packs, they can attack larger prey such as Dryosaurus, Gallimimus, and younger individuals of the larger herbivores. A large pack in the dry season can bring down larger prey working together, although this is a rarity. Preferred Habitat: With a general body plan, Segisaurus is able to take on nearly any environment without issue. They are often found in larger numbers in either the Mountain Ranges, where their nimbleness is helpful, or the West Delta, where food is plentiful nearly year round. Preferred Habitat: Adaptable to any habitat, but prefers upland and grassland areas Social Structure: Segisaurus tend to be more loosely social creatures than most of the other smaller species of dinosaurs on Isla Sorna. Individuals will flock together to hunt larger prey or protect nests, but they can be seen most of the year ranging from solo animals to small-medium sized packs. Description: One of the smallest of the carnivores on Isla Sorna, Segisaurus is one of the more primitive dinosaurs as well. Following the basic body plan of all theropod dinosaurs, they stand on two hind legs with a long, thin tail balancing them out. Their hands have three large fingers, and a single tiny little fourth finger that’s otherwise useless. Their heads are long and narrow, best for rummaging through carcasses and catching the occasional bug or fish. Their eyes are especially adapted however, at detecting ultraviolet light. This allows them to track prey via seat, saliva, and other bodily fluids that emerge when the venom begins to take effect. As the old saying goes, “You can run, but you can’t hide” Another unique feature of this species is a neurotoxin like venom excreted from the jaws. It is administered similarly like that of a Gila monster, by chewing it in. In small animals, a single bite is usually lethal, while it takes many bites to bring down larger animals with any affect. Once in the bloodstream, the venom begins immediately blocking all the sodium receptors, slowing victims down to be devoured while dying. Segisaurus rarely wait for their prey to die, often lunging in and eating while still alive. Behaviors: While Segisaurus is a dinosaur that seems to blend into the background with so many larger predators, they play a large role in the mainstay ecosystem of Isla Sorna. They act as a secondary cleanup crew, often feeding off of kills that large predators leave lying around. They in particular favor Ceratosaurus kills, as they tend to leave more on the carcass due to it being far too dirty for the larger predator’s tastes. Free food is free food to these opportunistic predators. Their most useful habit however, to Isla Sorna, is their particular love for Compsognathus. Often going out of their way to grab individuals or harass large packs, they grab them by as much as they can carry, dragging them off to tear apart and eat in smaller portions. This keeps the small carnivores from becoming too large in number, and helps attune the balance of Isla Sorna. Compy bites tend to have a much lessened effect, as their venom is extremely similar to that of Segisaurus. Their frequent nature to leave large trails behind them means that while most dinosaurs would flee a large pack of Compys, Segisaurs run towards it. Nesting time for these creatures can be spectacular displays if sighted. Groups ranging from the tens to the hundreds will meet up on riverbeds and streams, where males will display for the females. Once they mate, the two quickly build a nest secluded somewhere, more often than not in thorny vegetation. The male goes and hunts, often able to bring back several bodies of Compys in a short time period for its mate. When the eggs hatch, they care for the chicks for a few days before they’re able to defend themselves. While young can be viewed as food sources during the wet season, they more often form packs to help hunt larger prey. When coordinated, Segisaurus use their excellent speed and venomous bite to single out an individual. They quickly run and bite down, injecting as much venom as they can before their target kicks them off. Using speeds clocked up to 80 miles per hour, they then exhaust their prey, allowing the venom to course through their body faster and more evenly distributed. The prey usually falls down, and they leap upon it to devour it whole. Larger prey ranges from Dryosaurus to the occasional hadrosaur juvenile. In extremely large packs during the driest of dry seasons, they go and mob up, able to challenge larger prey items to survive. They communicate in hunts with a long whistle like call, amidst the normal cacophony of hisses, growls, and clacks. Their speed and venom allow them to be deadly predators, but with far many larger creatures dominating the pack hunter niche, such as Dilophosaurus and Velociraptor, makes pack hunting a rare event.
