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.
Typical adults of Albertosaurus and Gorgosaurus measured up to 8 to 9 m (26 to 30 ft) long, [4] [5] while rare individuals of Albertosaurus could grow to over 10 m (33 ft) in length. [6] Several independent mass estimates, obtained by different methods, suggest that an adult Albertosaurus weighed between 1.3 tonnes (1.4 short tons; 1.3 long ...
Finding no significant differences to separate the two taxa (due mostly to a lack of good Albertosaurus skull material), Dale Russell declared the name Gorgosaurus a junior synonym of Albertosaurus, which had been named first, and G. libratus was renamed Albertosaurus libratus in 1970. A species distinction was maintained because of the age ...

The higher and broader muzzles of tyrannosaurines like Daspletosaurus are mechanically stronger than the lower snouts of albertosaurines like Gorgosaurus, although tooth strengths are similar between the two groups. This may indicate a difference in feeding mechanics or diet. [57]
[10] [11] Albertosaurus, Gorgosaurus and Daspletosaurus all measured between 8 and 9 metres (26 and 30 ft) long, [12] while Tarbosaurus reached lengths of 11 metres (36 ft) from snout to tail. [13] The massive Tyrannosaurus reached 13 metres (43 ft) in the largest specimen, RSM P2523.8 .
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 ...
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 ...
