InGen Files Dilophosaurus (updated) by Miyess InGen Files Dilophosaurus (updated) by Miyess
Jurassic Park InGen Files: Dilophosaurus

Age: Early Jurassic (around 200-190 million years ago)

Diet: Carnivore

Length: Around 7 meters when full grown.

Weight: 0.5 tons


Notes: Dilophosaurus is one of the most iconic dinosaurs to feature in Jurassic Park. It gets its name from the two thin crests of bone that it sports on the top of its head, which are used as a display for courtship purposes. Dilophosaurus is nocturnal, hunting only at night (and sometimes early in the morning). We have found that Dilophosaurs are mostly ambush predators that live in the most remote parts of the jungle. This elusive predator spends the daylight hours sleeping in the foliage near rivers and streams in the dense jungle, out of sight of larger predators.

They are very inquisitive, likely a characteristic that gave these Jurassic age dinosaurs the edge over other reptiles of the day. As an early predatory dinosaur, Dilophosaurus does not have forward facing eyes, and thus it lacks stereo vision. They hunt in small packs, using scent as an integral part of their hunting techniques. Young Dilophosaurs can be deceptively harmless, but they are just as dangerous as their full grown counterparts. Nicknamed the “Spitter” by InGen staff, it is one of the most difficult dinosaurs to handle.

The connection between the premaxillary and maxillary bones of fossil specimens was very weak. This created a notch behind the first row of teeth. This information led to the early hypothesis that Dilophosaurus scavenged off dead carcasses, with the front teeth being too weak to bring down and hold large prey.

Dr. Wu decided to use frill-necked lizard (Chlamydosaurus kingii) DNA in combination with amphibian DNA to fill in the gaps in the degraded Dilophosaur genome, as he found it to be a particularly good fit with certain gene sequences, and he hoped the frill or at the very least, the aggressiveness of Chlamydosaurus would give the Dilophosaurs an edge in the face of larger predators on Isla Sorna. The frill can be expanded like a cobra's hood when the animal is feeling threatened or about to attack. It was partly expected, and is a means for them to intimidate larger animals that may attempt to steal their food. But the venom was a surprise. This ability to spit venom may have been due to Dr. Wu also using snake DNA (most likely spitting cobra) to fill in other gaps in the Dilophosaur genome.

The venom is a toxic cocktail of seven different enzymes, which cause extreme pain and irritation, resulting in rapid blindness and eventually paralysis. Dilophosaurus is able to spit its venom with great accuracy from quite a distance (in some rare cases as far as fifteen meters). They can also introduce venom to a prey item by biting, but they rarely do so in order to avoid the risk of injury. In this way the animal is still a predator despite its weak teeth and jaws.

Both the frill and the venom glands (under the tongue) are the direct result of InGen scientists splicing the Dilophosaur DNA with that of an Australian frill-necked lizard and some form of venomous snake (such as the spitting cobra).

Do you Think it will be seen in Jurassic World, i would like to see a adult specimen showing audience how big it really was. what other dinos would you like to see in JW.

It would be a huge mistake if they don't!

I agree, they should definitely have adult Dilophosaurs in jp4.

geesh, INGEN really went overboard by adding the frill!

Certain genes that influence one thing can be linked to other, unrelated physical traits. For instance; I vaguely recall reading something about how during domestication of wolves into dogs, when breeders selected for changes in behaviour (like tameness) it also resulted in changes in physical appearance or phenotype (like droopy/floppy ears as opposed to pointy ears that stand up). When you select for one trait, you flip the on switch for several other traits as well (so to speakl).

 

The same could be going on here: InGen scientists could have noticed that the genes from an Australian frill-necked lizard (that related to sex) were a perfect match to repair the damaged sex chromosomes in the Dilophosaurus DNA. Unbeknownst to them, those genes were also linked to the frill in the lizard (which originally evolved to impress a female but is also utilized as a method of frightening off a potential predator). As a result; the JP Dilophosaurs were endowed with an impressive frill. Though the scientists at InGen knew this could only have come from the foreign DNA, they decided to leave it be, as it made for an exotic addition to Jurassic Park.

Really cool, I like how you explained the frill and the toxic spit of the dilophosaurus! :D

Thanks! :)

I tried to make what InGen did with their Dilophosaurs as obvious as possible. It basically stemmed from people trying to tell me that the frill was the result of InGen splicing in King Cobra DNA. Though I agree that maybe the spitting abilities of the Dilophosaur could have come from Cobra DNA (And in the future I might add a silhouette of a spitting cobra to show this), I don’t think the frill can be explained by anything other than InGen using Australian Frill-neck Lizard DNA (as the shape/function is nearly identical in both animals).

Stay tuned for more InGen Files soon...
