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.The massive head of Albertosaurus was built for strength. It could withstand the shock as Albertosaurus crashed, open-mouthed, into its prey. Huge jaws carried the deadly sharp teeth, and spaces in the skull left room for bulging muscles.
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.
The rear legs of Albertosaurus were powered by large muscles that pulled on the bones to make them move. The ankle and metatarsals worked as part of the leg, giving a longer stride.Albertosaurus Dinosaurs is named after the Canadian province of Alberta.
