[Mapusaurus]], Carcharodontosaurus and Tyrannotitan which are among the largest known predatory dinosaurs.
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 relatives. However, with the description and publication in 2019 of Asfaltovenator vialidadi, a basal allosauroid displaying both primitive and derived features seen in Tetanurae, the new phylogenetic analysis has found Megalosauroidea to be a basal grade of carnosaurs in respect to Allosauroidea; thus significantly expanding Carnosauria's inclusiveness towards its original context.
Distinctive characteristics of carnosaurs include large eyes, a long narrow skull and modifications of the legs and pelvis such as the thigh (femur) being longer than the shin (tibia).
Carnosaurs first appeared in the Middle Jurassic, around 176 mya. The second last definite known carnosaurs, the carcharodontosaurs, became extinct in the Turonian epoch of the Cretaceous, roughly 90 mya;but modern Carnosaurs are such as Tuatara,Basilisk lizard?,Chameleon?,Crocodile they are few living Carnosaurs
