Gorgosaurus is a genus of tyrannosaurid theropod dinosaur that lived in
western North America during the Late Cretaceous Period, between about
76.5 and 75 million years ago. Fossil remains have been found in the
Canadian province of Alberta and possibly the U.S. state of Montana.
Like most known tyrannosaurids, Gorgosaurus was a bipedal predator
weighing more than a metric ton as an adult; dozens of large, sharp
teeth lined its jaws, while its two-fingered forelimbs were
comparatively small. It lived in a lush floodplain environment along
the edge of an inland sea. An apex predator, Gorgosaurus was at the top
of the food chain, preying upon abundant ceratopsids and hadrosaurs. In
some areas, it coexisted with another tyrannosaurid, Daspletosaurus.
Though these animals were roughly the same size, there is some evidence
of niche differentiation between the two. Gorgosaurus is the
best-represented tyrannosaurid in the fossil record, known from dozens
of specimens. These plentiful remains have allowed scientists to
investigate its ontogeny, life history and other aspects of its
biology.
