Dilophosaurus wetherilli

†Dilophosaurus wetherilli ('two-crested lizard of Wetherbill') is an Early Jurassic theropod from the Kayenta Formation of Arizona, USA. Reaching ~6 m, it is one of the largest Early Jurassic predators and is distinguished by twin bony crests along its skull. Despite its Jurassic Park portrayal, it bore no evidence of a neck frill or venom in the fossil record.

Diet & Feeding

Carnivore

Dilophosaurus wetherilli was a meat-eating predator. Carnivorous dinosaurs were active hunters or scavengers, equipped with sharp teeth and claws for catching and consuming prey. They occupied the top of the food chain in their ecosystems.

Time Period

Jurassic Early Mesozoic Era

Dilophosaurus wetherilli lived during the Jurassic Early period of the Mesozoic Era, approximately 201.4 to 174.7 million years ago.

After the Triassic-Jurassic extinction, dinosaurs rapidly diversified and became the dominant land vertebrates. Early sauropods and theropods began to evolve larger body sizes.
