What it looked like
Dilophosaurus was a fast, slender, bipedal (it walked on two legs), meat-eater from the late Triassic and early Jurassic periods. It weighed from 300kg to 450kg. It had a thin, bony, double crest on its head; these may have been for mating displays. It had short arms with three-fingered hands and strong legs with four-toed feet. Both fingers and toes had claws. It had hollow bones and an S-shaped, curved neck.

What it ate
Dilophosaurus was a carnivore, a meat eater. It had loosely attached jaws which would have made killing animals with its teeth difficult. It must have killed with its clawed arms and legs, and maybe scavenged bodies killed by other animals.

How it moved around
Dilophosaurus walked on two muscular legs and was a relatively fast runner. Some of its fossilized footprints show that only the claw-tips were touching the ground. This shows that Dilophosaurus may have been walking in water at the time. It's stride length (distance between footprints) was over 2 metres.

How it probably behaved
It may have moved around in packs, because 3 skeletons were found together.
