InGen Files Carnotaurus sastrei by Miyess InGen Files Carnotaurus sastrei by Miyess
Jurassic Park InGen Files: Carnotaurus sastrei

Age: Late Cretaceous (around 70-75 million years ago)

Diet: Carnivorous (ambush predator)

Length: Quite a large theropod, at about 8 metres in length when full grown.

Weight: 1.6 - 2 tons

Notes:This odd-looking carnivore is easily distinguishable from any other dinosaur bred by InGen. The most distinctive features of Carnotaurus are the two thick horns above the eyes, and the extremely reduced forelimbs with four basic digits, though only the middle two of these end in finger bones, while the fourth is splint-like and features an external 'spur.' The fingers themselves are fused and immobile, and lacked claws. It is also characterized by its unusually long neck (compared to other abelisaurs), and its small head with box-shaped jaws. Carnotaurs eyes face forward, which is unusual in a dinosaur, and indicate excellent binocular vision and depth perception. There is a rather puzzling contrast between Carnotaurus’ deep, robust-looking skull and its shallow, slender lower jaw. It is a midsized animal by dinosaur standards, and can be found Isla Sorna. Carnotaurus is easily recognized because of its horns, which are slightly larger in males than in females.

Once InGen scientists realized that they were working with Carnotaur DNA, they decided upon a rather interesting engineering approach for the species. Apart from the standard procedure of splicing in certain genes of amphibian origin into the degraded ‘fossil’ theropod DNA, the researchers decided to also include chameleon DNA to repair some of the genes associated with skin (among other things) in the animal because they knew from fossil evidence that Carnotaurus had bumpy, chameleon like skin. It was unknown if the original Carnotaur could change color like a chameleon, or if it’s skin only superficially resembled that of the lizard (it’s possible that the prehistoric Carnotaurus used its color changing ability in mating rituals or to express its mood to a rival, but we can never be certain of this), but as a result (which was almost to be expected), Jurassic Park Carnotaurs have the ability to change skin color and texture in an incredibly unique way and quite rapidly so. As a side effect, they also have chameleon-like swivelling eyes, and though they lack the ability to shoot their tongues out at prey, their tongues are quite sticky to the touch and are still useful in capturing small animals that would otherwise have been just out of reach. They also have a row of keratinous dorsal osteoderms (spikes) which run along the neck, back and tail, which help break-up the animals’ profile – helping it blend into its environment perfectly and stalk unsuspecting prey. They are ambush predators, which stand absolutely still while perfectly mimicking the environment they are in, they have even been observed swaying in time with the leaves around them. It seems that this hunting method first appeared in the jungles of Isla Sorna, for the prehistoric Patagonian habitat of the Carnotaur was not as densely forested and the real animal was more likely to have chased its prey. However, they are still capable of bursting out of the undergrowth at great speeds and running down prey quite easily. They commonly hunt from dusk till dawn, and sleep during the day. When confused or upset they turn chalky white (as the park rangers soon discovered by shining a torch on them) but they can be found in many different colour phases.

Carnotaurus was the topic of much discussion between the InGen board members and Park management. InGen thought the Carnotaurs were distinctly interesting, and that they should be included in the Park tour, while the rangers found the animals quite difficult to control. Carnotaurus is one of the less studied dinosaurs of Jurassic Park, and to date, much of its behaviour is somewhat unknown.

I have yet to design a Skull logo for this animal. Work in Progress.

Idea for displaying camouflage: have a Carnotaurus without anything behind it, and then a Carnotaurus with a background fence or something that shows through, with some sort of "camouflage" caption.

Yeah, I’m currently working on a re-make of this InGen File which is much more realistic. I’m actually quite happy with the way the new Carnotaurus has turned out. You can’t really tell that it has been spliced with chameleon DNA with the current version (at least not without looking at the DNA molecule and chameleon I’ve drawn in the bottom right), but the new version has some dead give-aways that it is part chameleon…

 

I was considering having the background be a dark forest with palm fronds/tree ferns hanging from above and a chain-link fence reaching half way up the page (www.psdgraphics.com/file/chain…, with the new Carnotaurus in the foreground sporting a pattern that somewhat matches both the leaves and the fence from background. How’s that?

That link doesn't work, but that's a good idea. I like it.

Slightly unrelated - the Carnotaurus wouldn't actually make that good of a chameleon/octopus dinosaur thanks to the scutes and armor on its skin...

Well in the novel it is described as a predator that hunts during the night/early morning hours, so the scutes/dermal armour would be hidden in the darkness and they could for the most part be buried in the skin. Also I’ve given the new version a ridge of scales that run along the back which would help to break up its’ outline and help it blend in…

Hmm...maybe its the recombinant stuff.

Oh yeah, definitely! The actual animal did not have these abilities. 

You're right about the scutes and armour, they would stand out a mile away... I don't think it mattered though; I vaguely remember a study that indicated that Carnotaurs were capable of great bursts of speed, and were most likely ambush hunters that burst out of the cover of trees and chased down anything that wandered past...
