Gorgosaurus and Albertosaurus are extremely similar, distinguished mainly by subtle differences in the teeth and skull bones. Some experts consider G. libratus to be a species of Albertosaurus; this would make Gorgosaurus a junior synonym of that genus. Gorgosaurus lived in a lush floodplain environment along the edge of an inland sea.
Albertosaurinae was recovered as including only Albertosaurus and Gorgosaurus. [3] Albertosaurus and Gorgosaurus are kept separate by most classifications, [2] [3] as should be according to Currie. [17] The cladogram below was found during the analysis of Nanuqsaurus by Anthony Fiorillo and Ronald Tykoski. [3]
Albertosaurus shared a similar body appearance with all other tyrannosaurids, Gorgosaurus in particular. Typical for a theropod, Albertosaurus was bipedal and balanced its large, heavy head and torso with a long, muscular tail.

Neither Daspletosaurus nor Gorgosaurus was more common at higher or lower elevations than the other. [56] However, while there is some overlap, Gorgosaurus appears to be more common at northern latitudes, with species of Daspletosaurus more abundant to the south. The same pattern is seen in other groups of dinosaurs.
A scientific publication by Phil Bell and colleagues in 2017 show that tyrannosaurids such as Gorgosaurus, Tarbosaurus, Albertosaurus, Daspletosaurus, and Tyrannosaurus had scales. The Bell et al. 2017 paper notes that the scale-like integument on bird feet were actually secondarily derived feathers according to paleontological and evolutionary ...
Nearby, The Gorgosaurus finds the Edmontonia outside its lair, but the bite to its leg is badly infected and it goes back into the cave to wait for easier prey to wander close. Six hundred miles away, the Edmontosaurus herd moves on through a volcanic ash field. Lying in wait, a pack of Albertosaurus sleeps until the herd is close enough to ...
Before the formal description of Nanuqsaurus, numerous tyrannosaurid teeth were known from the Kogosukruk Tongue of the Prince Creek Formation and were first referred to the genus Gorgosaurus. [1] Later, after the locale was understood to be younger than previously thought, the consensus switched to referring to the teeth under the genus ...
