How big was Dilophosaurus?

 

Length: Dilophosaurus could grow up to 7 metres (23 feet) long.

Height: It stood around 2 metres (6.5 feet) tall at the hips.

Weight: This dinosaur weighed between 400 to 500 kg (880 to 1100 lbs).

 

 

How did Dilophosaurus hunt?

 

Dilophosaurus was a carnivore and likely hunted smaller dinosaurs and other creatures. It used its sharp teeth and claws to catch and eat its prey. Its double crest on its head may have helped in hunting or scaring other animals. 

 

 

How Accurate is the Jurassic Park Dilophosaurus?

 

The portrayal of Dilophosaurus in the Jurassic Park movie is quite exaggerated. In the film, it is shown with a frill and the ability to spit venom, but there is no scientific evidence to support these features. Modern research shows Dilophosaurus had crests on its head but did not have the frill or venomous abilities.
