Ceratosaurus

Ceratosaurus is a genus of carnivorous theropod dinosaurs from the Late Jurassic of North America and Europe, distinguished by a prominent nasal horn and small horns above the eyes.

Theropoda: Theropoda is a dinosaur group that includes most meat-eating dinosaurs and modern birds. Ceratosaurus belongs to this broad group of mostly bipedal dinosaurs.
Ceratosaurus nasicornis: Ceratosaurus nasicornis is the type species of Ceratosaurus, named from fossils found in Colorado. Its well-known remains established the genus and its characteristic horned skull.
Carnivory: Carnivory is a mode of nutrition in which an organism obtains food by consuming animals. Ceratosaurus was a meat-eater with jaws and teeth adapted to seize prey.
Allosaurus fragilis: Allosaurus fragilis is a large Late Jurassic theropod species from western North America. It was a larger contemporary predator with a different skull and body build.
Ceratosauria: Ceratosauria is a theropod clade that includes Ceratosaurus and its close relatives. This clade gives Ceratosaurus its place among early-diverging theropods.
Cleveland-Lloyd Dinosaur Quarry: Cleveland-Lloyd Dinosaur Quarry is a Jurassic fossil site in Utah rich in theropod remains. Its fossils include Ceratosaurus alongside other predators from the Morrison Formation.
Theropod locomotion: Theropod locomotion concerns how theropod dinosaurs moved, usually on two hind limbs. Its limb proportions and trackway context inform reconstructions of its movement.
Torvosaurus: Torvosaurus is a genus of large megalosaurid theropods from the Late Jurassic. It represents another large predator that shared parts of Ceratosaurus's range.
Dinosauria: Dinosauria is the group of reptiles that includes extinct dinosaurs and living birds. Ceratosaurus is one branch of the dinosaur family tree.
Morrison Formation: The Morrison Formation is a Late Jurassic geological formation in western North America containing abundant dinosaur fossils. Many North American Ceratosaurus specimens come from this formation.
