![]() There, it lived alongside prosauropods and the armoured Scutellosaurus, as well as an Early Jurassic species of Coelophysis (which coincidentally also bore head crests), once one of the most abundant predators in the Late Triassic. However, its portrayal as a social animal might be accurate due to multiple individuals being found together alongside a trackway of criss-crossing footprints and the possible use of the crests for display and social signaling.ĭilophosaurus is known from the Kayenta Formation, which was primarily deposited by rivers. It also didn't live in Asia (this probably comes from a mixup with Sinosaurus, a similar but unrelated large crested theropod). The real-world animal was also far larger at over twice the length and almost twice the height of the in-game creatures. Unlike the Jurassic Park canon, the real Dilophosaurus almost certainly didn't have an extendable frill or the ability to spit poison as no living ancestor or relative of birds, crocodiles, or dinosaurs possesses such features. Studies on caloric intake and probable diet based on dentition suggest Dilophosaurus was a generalist carnivore, and the aforementioned 2020 study shows that it would have been more than capable of taking on big game (though the possibility of at least occasional piscivory was not ruled out). ![]() It was later hypothesized to have been a fish-eater based on the notch at the end of its jaw (a feature common in piscivorous archosaurs like phytosaurs and spinosaurs), its long arms and claws, and its fluvial habitat. This redescription also found that it was a far more powerful predator than had been previously thought, and that its two bony crests may have been the core of a much larger ornamental structure.įor many decades the known material of Dilophosaurus painted a picture of a very delicate animal that couldn't take on large prey, which led researchers to suggest that it only ate small animals or scavenged the kills of more capable predators. However, the genus was redescribed in 2020 and found not to be particularly closely related to any of these dinosaurs, making Dilophosauridae invalid. ![]() It was believed to be a part of a family called Dilophosauridae, a group of early carnivores identified by their elaborate crests that acted as display features for attracting mates, including Sinosaurus from China, Dracovenator from South Africa, and Cryolophosaurus from Antarctica. Like many primitive theropods it had eyes on either side of its head, and so could not see directly ahead. At around 20 feet long, it was a medium-sized dinosaur compared to many later theropods, but during the Early Jurassic, it was the largest predator on land. Jungle: Isla Muerta Challenge Mode Jurassic Difficulty Unlock Paleontologyĭilophosaurus lived in what is now Arizona in the Kayenta Formation. They will fight with Velociraptor and other small carnivores, but can live alongside large carnivores. They are resistant to bracken poisoning and have relatively long lifespans. It is a gregarious carnivore and can live either alone or in packs of up to twelve individuals. Gameplay Evolution Behaviourĭilophosaurus is one of the less expensive carnivores. As large as a modern brown bear, the most distinctive features of the Dilophosaurus cloned by InGen are their two-crested heads, and a multi-colored frill, which extends itself when the animal is attacking, usually by spitting venom at its prey. ![]() The base genome of the Dilophosaurus is primarily dark green, with red, yellow and white stripes adorning various parts of the body. After the eruption of Mount Sibo in 2018, it is unknown if there are any surviving populations. Like the other animals in the park, Jurassic World's Dilophosaurus underwent frequent medical care, with a noted problem being a fungal infection which frequently appeared on the animal's decorative frill. ĭilophosaurus was one of a large number of dinosaurs exhibited in Jurassic Park's successor, Jurassic World, which opened on Isla Nublar in 2004. A year after the incident, it was reported during a cleanup operation on Nublar that the population of Dilophosaurs had remained constant. During the Jurassic Park incident in 1993, a Dilophosaurus attacked park employee Dennis Nedry after his car crashed close to the creature's paddock, using its venom to subdue and kill him. Originating in the Jurassic period, a total of seventeen Dilophosaurs were bred by InGen, with five present on Isla Nublar and twelve on Isla Sorna.
