Albertosaurus Dinosaur (al-BURR-to-SORE-us) is the species name for several species of tyrannosaurids that looked similar to Tyrannosaurus rex, but were rather smaller. Albertosaurus Dinosaur also tended to be less massive than T. rex, as fine as its contemporary Daspletosaurus (also a tyrannosaurid of similar length).

The co-existence of these two animals have lead to the proposal that they were specialized for killing different kinds of prey: Albertosaurus Dinosaur may have went after fleeter prey, like duck-billed dinosaurs and ornithomimids, while Daspletosaurus tackled heavier horned dinosaur.

Like Tyrannosaurus, Albertosaurus had small arms and a enormous head with recurved serrated teeth. These teeth however, are more powerfully curved than those of Tyrannosaurus Dinosaur.

Unlike Tyrannosaurus, who underwent much evolutionary modify, all discovered specimens of Albertosaurus Dinosaur suggest that they didn't evolve much in over 10 million years, apart from for a trend towards a more slender or gracile form.

Albertosaurus Dinosaurs is named after the Canadian province of Alberta.
