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 Carcharodontosaurus, Giganotosaurus, Mapusaurus, and Tyrannotitan which are among the largest known predatory dinosaurs.
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).

As some of the top predators of the Jurassic, Allosaurs constantly made their appearance, mainly as hunters
of Diplodocus with varying success. They mainly hunted the younger animals, while adult dinosaurs could fighting them off.
This episode featured Australovenator, originally identified as Polar Allosaur. It was one of the biggest terrestrial carnivores of the Cretaceous Antarctica, hunting various herbivores, from Leaellynasaura to Muttaburrasaurus with various success. Unlike Allosaurus, Australovenator was a loner and didn't tolerate other members of its kind, even females.
An Allosaurus named Big Al was the main character of this WWD special, from his birth to death.
Mapusaurus, a carnosaur, is one of the viewable dinosaurs in this app.
