Dilophosaurus (/ d aɪ ˌ l oʊ f ə ˈ s ɔːr ə s,-f oʊ-/ [1] dy-LOH-fə-SOR-əs, -foh-) is a genus of theropod dinosaurs that lived in what is now North America during the Early Jurassic, about 186 million years ago. Three skeletons were discovered in northern Arizona in 1940, and the two best preserved were collected in 1942.
[148] [149] The film's Dilophosaurus also has a fictionalized neck frill that retracts, and the dinosaur was made significantly smaller to ensure that audiences would not confuse it with the Velociraptors. [150] [10] While the real Dilophosaurus was thought to have stood at around 10 feet (3.0 m), the animatronic was only four feet in height ...
During the Early Jurassic Period, dinosaurs such as Dilophosaurus, Anchisaurus, Coelophysis (formerly known as Megapnosaurus), and the early thyreophoran Scutellosaurus lived in North America. The latter is believed to have been the ancestor of all stegosaurs and ankylosaurs.
Mounted skeletons of Tyrannosaurus (left) and Apatosaurus (right) at the AMNH. Dinosaurs are a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago, although the exact origin and timing of the evolution of dinosaurs is the subject of active research.
However, in 2012, Matthew Carrano found that Cryolophosaurus was a tetanuran, related to Sinosaurus, but unrelated to Dilophosaurus. [20] In 2020, a monograph of Dilophosaurus found Cryolophosaurus to be a derived neotheropod, close to Averostra, in a more derived position than Zupaysaurus, but less than Dilophosaurus. [21]

Eubrontes is the name of the footprints, identified by their shape, and not of the genus or genera that made them, which is as yet unknown but is presumed to be similar to Coelophysis or Dilophosaurus. They are most famous for their discovery in the Connecticut River Valley of Massachusetts in the early 19th century. They, among other ...
