The Dilophosaurus was discovered in 1940 by Jesse Williams, in Navajo County in Arizona.
The Dilophosaurus got its scientific name Dilophosaurus wetherilli in 1970 from Samuel P. Wells.
The name Dilophosaurus means: Two-Crested Lizard.
The name Dilophosaurus is pronounced: “dye-LO-fuh-SAWR-us”.
The Dilophosaurus was part of a group of dinosaurs known as Theropods.
They lived in the Early Jurassic Period around 193 million years ago.
The holotype specimen discovered in 1940 weighed 624 pounds, the largest Dilophosaurus specimen ever recovered weighed 880 pounds.
The holotype specimen discovered in 1940 was 19.8 feet long, the largest Dilophosaurus specimen ever recovered was 23 feet long.
The Dilophosaurus was an active carnivore and paleontologists believe they may have hunted dinosaurs as large as prosauropods.
In 2017, American paleontologists Milner and James Kirkland suggested some of the features of the Dilophosaurus indicated that it could have eaten fish and other marine animals.
In 2017, Connecticut designated the Dilophosaurus as their state dinosaur.
The Dilophosaurus was featured in the 1993 movie Jurassic Park, a move adaption of Michael Crichton's 1990 novel Jurassic Park.
The Dilophosaurus featured in the 1993 movie Jurassic Park was shown to be able to spit venom and sporting a foldable neck frill around its next. In real life, the Dilophosaurus did not have a neck frill and could not spit venom. This was done to make it easy for the audience to tell the difference between the Dilophosaurus and the Velociraptor.
