Fossil range: Middle Jurassic–Late Cretaceous
A replica Allosaurus skeleton.
| Scientific classification
Carnosauria is a group of large predatory dinosaurs that lived during the Jurassic and Cretaceous periods. While it originally contained a wide assortment of giant theropods that were not closely related, the group has since been defined to encompass only the allosaurs and their closest kin. Recently, scientists have discovered some very large carnosaurs in the carcharodontosaurid family such as Giganotosaurus and Tyrannotitan which are among the largest known predatory dinosaurs.
Carnosauria has traditionally been used as a dumping ground for all large theropods, but analysis in the 1980s and 1990s revealed that other than size, the group shared very few characteristics. Most former carnosaurs were reclassified as more primitive theropods. Others were placed in Coelurosauria if they were more closely related to birds, like the tyrannosaurids. Other former carnosaurs include the megalosaurids, the spinosaurids, and the ceratosaurs. Even non-dinosaurs have been considered carnosaurs, such as the rauisuchian Teratosaurus.

"Carnosaurus" is an informal generic name, attributed to Friedrich von Huene, 1929, that is sometimes seen in lists of dinosaurs. It is probably a typographical error; von Huene intended to assign indeterminate remains to Carnosauria incertae sedis, but at some point in the process of publication, the text was revised to make it appear that he was creating a new generic name "Carnosaurus" (as described by George Olshevsky in a 1999 post to the Dinosaur Mailing List). The name is undescribed and has not been used seriously.
