About Alberfosaurus:

As carnivorous dinosaurs go, Albertosaurus is fairly well known, with multiple, more-or-less complete fossils having been dug up in North America (many in the Canadian province of Alberta, after which this dinosaur is named).

For all intents and purposes, Albertosaurus can be considered a slightly smaller version of T. Rex, "only" about three tons (compared to more than twice that for the largest T. Rexes) but every bit as dangerous. This tyrannosaur made its living by hunting the numerous herbivorous dinosaurs of the late Cretaceous.

Scarily, paleontologists have found evidence that Albertosaurus may have hunted in packs. If this is true, then it's likely that not even armored, adult herbivores of this place and time (such as Triceratops) were truly safe.
