Albertosaurus shared many features in common with its tyrannosaurid relatives. It had a large head full of sharp teeth, two strong back legs and two small, two-fingered arms.
Compared to many other tyrannosaurs, Albertosaurus was more slender and agile. It wasn’t quite as large as Tyrannosaurus or Tarbosaurus, but it was larger than others like Alioramus and Qianzhousaurus.
While there is some debate about whether tyrannosaurids were scaled or feathered, all known skin impressions of Albertosaurus show scales.
