Gorgosaurus libratus, a fearsome theropod dinosaur, roamed North America about 76 million years ago. This apex predator boasted powerful hind limbs, sharp teeth, and a keen sense of smell. Typically inhabiting floodplain environments, it played a crucial role in maintaining the ecosystem's balance by preying on herbivorous dinosaurs.

Gorgosaurus libratus was native to what is now western North America. It predominantly inhabited areas that are currently part of Alberta, Canada, and potentially parts of Montana, USA, during the Late Cretaceous period, approximately 76 to 75 million years ago.

Gorgosaurus libratus lived in a warm, semi-arid climate with seasonal variations. This region during the Late Cretaceous was characterized by a coastal plain environment with rivers, floodplains, and forests. The landscape supported a variety of plant life, including conifers and flowering plants.

As a large theropod dinosaur, Gorgosaurus libratus occupied the niche of an apex predator. It likely preyed on herbivorous dinosaurs and smaller vertebrates. Its habitat supported diverse ecosystems that included other dinosaur species, providing ample prey and competition.
