Size of the largest known (left) and holotype (right) specimens compared to a human. Dilophosaurus was one of the earliest large predatory dinosaurs, a medium-sized theropod, though small compared to some of the later theropods. [2] [5] It was also the largest known land-animal of North America during the Early Jurassic. [6]
This list of nicknamed dinosaur fossils is a list of fossil non-avian dinosaur specimens given informal names or nicknames, in addition to their institutional catalogue numbers. It excludes informal appellations that are purely descriptive (e.g., "the Fighting Dinosaurs", "the Trachodon Mummy").
Dilophosaurus skull reconstruction by Brian Engh; Dilophosaurus skeletal by Scott Hartman "A comprehensive anatomical and phylogenetic evaluation of Dilophosaurus wetherilli (Dinosauria, Theropoda) with descriptions of new specimens from the Kayenta Formation of northern Arizona."
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.
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 ...
Speculative size compared to a human. Dracovenator is estimated to have measured between 5.5 and 6.5 m (18 and 21 ft) in length and 250 kg (550 lb) in body mass. [2] [3] The holotype specimen, BP/1/5243, consists of both premaxillae, a fragment of the maxilla, two dentary fragments, a partial surangular bone, a partial angular bone, a partial prearticular bone, an articular bone, and several ...
The Dilophosaurus scene was shot on a sound stage, and the animal's lower body was suspended from a catwalk with bungee cords. No CGI was used in creating the Dilophosaurus. [154] In both the novel and its film adaptation, a Dilophosaurus uses its venom on the character Dennis Nedry before killing him. [154]
A large, short-tailed species with heterogeneous dorsal scalation and a discontinuous vertebral crest. There are several slightly enlarged scales below the tympanum, a row of enlarged submaxillaries and a series of large, lanceolate scales on the anterior edge of the gular pouch.
