This list of non-avian theropod type specimens is a list of fossils that are the official standard-bearers for inclusion in the Mesozoic species and genera of the dinosaur clade Theropoda, which includes the carnivorous dinosaurs like Tyrannosaurus and Velociraptor, their herbivorous relatives like the therizinosaurs, and birds.
[9] [5] In 1985, Bonaparte published a note presenting Carnotaurus sastrei as a new genus and species and briefly describing the skull and lower jaw. [5] The generic name Carnotaurus is derived from the Latin carno [carnis] ("flesh") and taurus ("bull") and can be translated with "meat-eating bull", an allusion to the animal's bull-like horns.

Brachyrostra (meaning "short snouts") is a clade within the theropod dinosaur family Abelisauridae.It includes the famous genera Carnotaurus, Aucasaurus, potentially Abelisaurus as well as their close relatives from the Cretaceous Period of Argentina and Brazil plus Caletodraco from France. [1]
Carnotaurus is a genus of large theropod dinosaur that lived in South America during the Late Cretaceous period, between about 72 and 70 million years ago. The only species is Carnotaurus sastrei . Known from a single well-preserved skeleton, it is one of the best-understood theropods from the Southern Hemisphere .
Many dinosaur specimens have been sold at auction, as part of the fossil trade.On average, around five dinosaur skeletons are put up for auction each year. [1] These specimens are mostly purchased by wealthy private collectors and museums in Europe and the United States, though interest has been growing in China as well. [1]
The Dinosaur Discovery Museum in Kenosha, Wisconsin, United States, is dedicated to the exploration and explication of the relationship between modern birds and ancient carnivorous biped dinosaurs, the theropods, which include Carnotaurus, Tyrannosaurus rex, and Archaeopteryx. This link is especially well documented in the fossil record.
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.
This specimen was the first occurrence of a hadrosaur in south-central Alaska, one out of only four vertebrate fossils from the entire Wrangellia Composite Terrane, and the first associated skeleton of an individual dinosaur in Alaska.
