Dilophosaurus: The Real Dinosaur Behind the “Jurassic Park” Myth
While the Dilophosaurus gained widespread recognition from its portrayal in the 1994 film “Jurassic Park,” the real creature was quite different from its Hollywood depiction. Unlike the small, frilled, venom-spitting dinosaur in the movie, the actual Dilophosaurus was a formidable predator of the early Jurassic era, standing at least 8 feet tall and stretching over 20 feet in length.
The cinematic version of Dilophosaurus introduced several fictitious traits, such as a flaring frill and venomous spit, both of which lack any fossil evidence. However, the dinosaur did possess two notable crests on its head, lending it the name “two-crested lizard.” These crests are believed to have served mainly for display, perhaps to attract mates or for communication among individuals.
Significant fossil discoveries of Dilophosaurus have been made in the sandstones of the Kayenta Formation, located on the Navajo Nation east of Cameron, Arizona. The Navajo Nation has collaborated with museums to preserve these valuable fossils, ensuring they are carefully studied and displayed. Notably, a well-preserved Dilophosaurus skeleton restoration is showcased at the Museum of Northern Arizona in Flagstaff.
Due to the exceptional quality of the fossils and comprehensive research, Dilophosaurus is arguably the most thoroughly understood dinosaur from the early Jurassic period.
