Originally described by Barnum Brown in the Horseshoe Canyon formation of Canada, this ferocious Tyrannosaurid was smaller than T. rex but would have preyed upon many of the same groups of prey animals as that giant relative. The genus is named for Alberta, Canada and the localities where this ferocious dinosaur was discovered and the species name translates to "flesh-eater", an appropriate moniker when one considers the many sharp teeth that lined the massive jaws of this specimen.
