Ceratosauria

Ceratosauria is a group of theropod dinosaurs that includes Ceratosaurus, abelisaurids, and their relatives. Its members lived mainly during the Jurassic and Cretaceous periods.

Theropoda: Theropoda is the dinosaur group that includes birds and all non-avian theropods, mostly bipedal carnivores. Ceratosauria is one major branch within this broader dinosaur group.
Carnotaurus: Carnotaurus is a Late Cretaceous abelisaurid from Argentina, notable for paired brow horns and exceptionally short forelimbs. Its unusually complete skeleton reveals the distinctive proportions of an abelisaurid ceratosaur.
Ceratosauria phylogeny: Ceratosauria phylogeny is the reconstruction of evolutionary relationships among ceratosaurs and their relatives. Different fossil characters and analyses yield competing arrangements of ceratosaur branches.
Theropod feeding: Theropod feeding encompasses the diets and food-acquisition strategies of meat-eating and omnivorous theropod dinosaurs. Ceratosaur skulls and teeth provide evidence for varied feeding strategies within the group.
Gondwanan dinosaurs: Gondwanan dinosaurs are dinosaurs known from the ancient southern landmasses of Gondwana. Ceratosaurs became prominent predators in several Gondwanan dinosaur communities.
Neotheropoda: Neotheropoda is a major theropod clade that includes ceratosaurs, tetanurans, and birds. This broader clade places Ceratosauria among the earliest-diverging major theropod lineages.
Majungasaurus: Majungasaurus is a Late Cretaceous abelisaurid from Madagascar known from unusually abundant fossil material. Its fossils document ceratosaur life on an island continent during the Cretaceous.
Coelophysoidea: Coelophysoidea is an early-diverging theropod group whose members are generally outside Ceratosauria. Its relationship to Ceratosauria has been debated in interpretations of early theropod evolution.
Theropod locomotion: Theropod locomotion is the study of how theropod dinosaurs moved, primarily on two legs. Limb proportions and trackways help reconstruct ceratosaur movement and body mechanics.
South American dinosaurs: South American dinosaurs are dinosaur taxa known from fossils on the South American continent. Abelisaurids and other ceratosaurs are central to the continent’s Cretaceous predator record.
