Did Dilophosaurus spit venom?

How accurate is Jurassic Park Dilophosaurus?

The Jurassic Park films depict Dilophosaurus as a small, venom-spitting dinosaur with a dramatic frilled neck. These traits, however, are entirely fictional; real Dilophosaurus was much larger and lacked both the frill and any evidence of venom. The film's imaginative additions were created for suspense and visual impact, while scientific reconstructions depict Dilophosaurus as a formidable predator with a slender, crested skull and no special defensive adaptations.

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.

Modern-day Dilophosaurus

Brachiosaurus looked a bit like a giant giraffe with a very long neck and relatively short tail. Unlike most other dinosaurs, their front legs were longer than their back legs, hence their name "arm lizard." They had expanded nasal bones on the top of their heads, allowing them to breathe easily while eating.

Was Dilophosaurus venomous?

There is no fossil evidence to suggest that Dilophosaurus was venomous. The idea of Dilophosaurus spitting venom was popularised by the 1990 novel "Jurassic Park" and its 1993 movie adaptation, but it was a fictional addition to make the dinosaur appear more dangerous.
