Brachyrostra
Sign in to saveAlso known as Brachyrostran, Brachyrostrans
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. The group was first proposed in an analysis conducted by Juan Canale and colleagues in 2008. They found that all South American abelisaurids described up to that point grouped together as a sub-clade of Abelisauridae, which they named based on the relatively unusual shape of their skulls (in comparison wit

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. The group was first proposed in an analysis conducted by Juan Canale and colleagues in 2008. They found that all South American abelisaurids described up to that point grouped together as a sub-clade of Abelisauridae, which they named based on the relatively unusual shape of their skulls (in comparison with other theropods). They defined the clade Brachyrostra as "all the abelisaurids more closely related to Carnotaurus sastrei than to Majungasaurus crenatissimus."
