Dilophosaurus

Dilophosaurus is a genus of large theropod dinosaur from the Early Jurassic of what is now the southwestern United States. Its skull bore a pair of thin crests.

Theropoda: Theropoda is the dinosaur group that includes birds and all non-avian meat-eating dinosaurs. Dilophosaurus belongs to this broad group of predominantly bipedal dinosaurs.
Kayenta Formation: The Kayenta Formation is a geological rock unit in the southwestern United States dating to the Early Jurassic. The principal Dilophosaurus fossils come from this formation in Arizona.
Predation: Predation is an interaction in which one organism captures and consumes another. Dilophosaurus was a carnivorous theropod, though its exact prey and hunting behavior remain uncertain.
Jurassic Park (film): Jurassic Park is a 1993 science-fiction film directed by Steven Spielberg and adapted from Michael Crichton's novel. Its venom-spitting, frilled Dilophosaurus is fictional; fossils show neither feature.
Samuel Paul Welles: Samuel Paul Welles was an American paleontologist who studied and named Dilophosaurus. Welles described the genus from Arizona fossils and established its scientific identity.
Dinosaur: Dinosaurs are a group of archosaurs distinguished by features of their hip, limbs, and other skeletal anatomy. This broader group includes Dilophosaurus and its theropod relatives.
Dilophosaurus wetherilli: Dilophosaurus wetherilli is the type species of the dinosaur genus Dilophosaurus. This named species anchors the genus and is represented by the best-known specimens.
Bipedalism: Bipedalism is locomotion using two limbs for walking or running. Dilophosaurus's hindlimb anatomy indicates a two-legged stance and gait.
Coelophysis: Coelophysis is a small-bodied theropod dinosaur known from Late Triassic fossils in North America. It provides a smaller, earlier North American theropod comparison to Dilophosaurus.
Navajo Nation: The Navajo Nation is an Indigenous territory spanning parts of Arizona, New Mexico, and Utah. Important Dilophosaurus fossil localities lie within the Nation's lands in Arizona.
