Albertosaurus was a theropod, a member of the family Tyrannosaurids. Albertosaurus belonged to the more fearsome predators of Cretaceous period. Its name means "lizard from Alberta", because many fossils have been found in Alberta, Canada. This smaller tyrannosaurus was similar to the Tyrannosaurus rex, though it roamed some eight million years before. Albertosaurus was a fierce hunter, a carnivore. It probably ate plant-eating dinosaurs, probably the carcasses of dead animals as well. It swallowed flesh in large chunks, without chewing them. Albertosaurus was one of the fastest runners among the tyrannosaurids. It was bipedal animal, like all tyrannosaurs. Its strong hind limbs were long and powerful, each foot had three toes with large, sharp claws. Its front limbs had two fingers and were too short to reach its head; the function of its small arms is not known. Albertosaurus had a large head, strong and muscular neck and a long tail. It possessed a wide muzzle on its large skull, lined with sharp, long, saw-toothed teeth, suitable for meat eating. Its teeth were perfect for tearing flesh and its powerful jaws were used to rip carcasses apart.
