Carnosaurs

Of all the theropods, the ferocious carnosaurs are probably the most famous. Some carnosaurs could run as fast as 22 mph (35 km/h) on their large and powerful back legs. Massive heads carried a fearsome array of enormous serrated and curved teeth. Tyrannosaurus rex was the largest of the carnosaurs, and the most successful predator in the Cretaceous period. During the Jurassic, Allosaurus was the top predator.

Allosaurus foot

Like all carnosaurs, Allosaurus walked on three large, clawed toes. The feet were strong because they had to bear the weight of the body. The first toe was small and faced backward, off the ground.

Complete carnosaur skeletons are a rare find. There have been many finds of Allosaurus parts, including more than 60 skeletons in one quarry, so a complete picture of this powerful carnivore can be created.

Big predator About 145 million years ago, Albsaurus was the terror of sauropods, ornithopods, and stegosaurs. At about 36 ft (11 m) long, and weighing as much as 2 tons (tonnes), Albsaurus was one of the most common dinosaurs during this time, and would have been well supplied with prey.
