| Sam Welles was taken to the first dilophosaurus specimens ever found, in the Kayenta Formation, in 1942, located in Arizona. A Navajo named Jessie Williams had discovered the specimen in 1940 and took Sam Welles, Ed Kott, and Bill Rush to the location two years later. |
| From the first discovery of the dilophosaurus in 1942 came two specimens that were able to be excavated and taken to Berkeley. The third was too weathered. |
| In 1954 the two specimens discovered by Sam Welles were named Megalosaurus wetherilli. |
| In 1964 Sam Welles discovered another specimen near the original three. This specimen had the double crests, unlike the first three. This specimen was given the name dilophosaurus. |
| Dilophosaurus is derived from Greek words meaning two, crest, and lizard, which translates to two-crested lizard. |
| The dilophosaurus portrayed in the movie Jurassic Park was not as accurate as it likely was in real life. The dilophosaurus portrayed in the movie was capable of spewing poison while in real life it was much larger and likely had no need for poison. |
| The dilophosaurus has been portrayed in the movie Jurassic Park movie as having a neck frill. This was not the case in reality. |
| Despite being considered a dinosaur that lived exclusively in the southwest American region, footprints that may have belonged to the dilophosaurus were found in the 1840s in Connecticut and Massachusetts. |
| The design of the dilophosaurus' teeth have led scientists to believe that it may not have been capable of taking down larger prey, as the back teeth in the upper jaw were weekly rooted. |
| The dilophosaurus is believed to have sat like a bird, in an upright position. |
| Some scientists believe that the dilophosaurus may have been a fish-eater. The design of its teeth and shape of its nostrils lends itself to the idea that its nostrils could have kept above water and its teeth would have been ideal for puncturing fish. |
| Some scientists believe that the dilophosaurus ate smaller dinosaurs. |
| Some scientists believe that the dilophosaurus may have been feathered due to imprints found in mud. Others believe this imprinting was simply from the dilophosaurus shifting its weight. |
| A specimen found in China in 1987 has been classified as a dilophosaurus sinensis. After further examination in 2013 it was determined to be a Sinosaurus triassicus. This means that the only specimens of dilophosaurus have been found in the American Southwest to date. |
