Dilophosaurus was a carnivore (meat-eater) that lived in
between about 200 and 190 million years ago.
Fossils of the animal
have been found in
Dilophosaurus was about 20 feet (6 meters) long, and about 5 feet (1.5 meters)
tall at the hips. It weighed around 1,000 pounds (450 kilograms).
The most unusual feature of Dilophosaurus are the pair of crests on its skull
(it is from this feature that it gets its name, which means "two-crested lizard").
It is thought that these crests were probably used for display, probably attracting mates,
and may have been large in one sex than the other.
Dilophosaurus featured in the first of the
Jurassic Park movies
(and in the Jurassic Park novel).
In the movie depiction, it appears a bit of creative license was used:
The Jurassic Park version of Dilophosaurus is shown as much smaller than the actual animal.
The Jurassic Park version of Dilophosaurus is shown with a expandable neck-frill, and with the ability to
spit poison - there is no evidence that the real animal had either of these features.
Although the Jurassic Park version of Dilophosaurus may not be 100% technically accurate, it has proven to be popular
- and some video games and even music videos appeared to have been inspired by
Dilophosaurus was a member of the Saurischia ("lizard-hipped") order of dinosaurs. What this means, is that although Dilophosaurus was not closely related to lizards, it did have similarly shaped pelvic bones.
Dilophosaurus was a Theropod - a member of a group of related bipedal dinosaurs that included the ancestors of birds (although Dilophosaurus was not itself an ancestor of birds).
Dilophosaurus lived between about 200 million years ago and 190 million years ago, during the late Jurassic period.
Dilophosaurus lived in North America and Asia.
