Bonaparte, 1985. Carnotaurus (/ ˌkɑːrnoʊˈtɔːrəs /; lit. 'meat bull') is a genus of theropod dinosaur that lived in South America during the Late Cretaceous period, probably sometime between 72 and 69 million years ago. The only species is Carnotaurus sastrei. Known from a single well-preserved skeleton, it is one of the best-understood ...
Carnosauria is an extinct group of carnivorous theropod dinosaurs that lived during the Jurassic and Cretaceous periods.. While Carnosauria was historically considered largely synonymous with Allosauroidea, some recent studies have revived Carnosauria as clade including both Allosauroidea and Megalosauroidea (which is sometimes recovered as paraphyletic with respect to Allosauroidea), and thus ...
Ceratosauria derives its names from the type species, Ceratosaurus nasicornis, described by O.C. Marsh in 1884. A moderately large predator from the Late Jurassic, Ceratosaurus nasicornis, was the first ceratosaur to be discovered. Ceratosaurs are generally moderately large in size, with some exceptions like the larger Carnotaurus and the ...
Allosaurus (/ ˌæləˈsɔːrəs /) [2][3] is an extinct genus of large carnosaurian theropod dinosaur that lived 155 to 145 million years ago during the Late Jurassic period (Kimmeridgian to late Tithonian ages). The name " Allosaurus " means "different lizard", alluding to its unique (at the time of its discovery) concave vertebrae.
Brachyrostra (meaning "short snouts") is a clade within the theropod dinosaur family Abelisauridae. It includes the famous genera Carnotaurus, Abelisaurus, Aucasaurus as well as their close relatives from the Cretaceous Period of Argentina and Brazil plus Caletodraco from France [1]. The group was first proposed in an analysis conducted by Juan ...
The remains show some similarities to Carnotaurus sastrei, causing the describers to assign Xenotarsosaurus to the Abelisauridae, which has remained a common determination. However, it has also been proposed that Xenotarsosaurus is a neoceratosaurian of uncertain affinities.
Ceratosaurus. Ceratosaurus / ˌsɛrətoʊˈsɔːrəs / (from Greek κέρας/κέρατος, keras/keratos meaning "horn" and σαῦρος sauros meaning "lizard") was a carnivorous theropod dinosaur that lived in the Late Jurassic period (Kimmeridgian to Tithonian ages). The genus was first described in 1884 by American paleontologist ...
Deinotherium is an extinct genus of large, elephant-like proboscideans that lived from about the middle-Miocene until the early Pleistocene.Although its appearance is reminiscent of modern elephants, Deinotherium possessed a notably more flexible neck, with limbs adapted to a more cursorial lifestyle, as well as tusks which grew down and curved back from the mandible, as opposed to the forward ...
