Its fossil remains have been found mainly in Canada, especially in the Dinosaur Park Formation, which has allowed a detailed understanding of its anatomy and ontogeny.\u003c\/p\u003e\n\u003cp data-end=\"945\" data-start=\"479\"\u003eMorphologically, \u003cem data-end=\"538\" data-start=\"516\"\u003eGorgosaurus libratus\u003c\/em\u003e was a large bipedal predator, with an estimated length of 8 to 9 meters, a hip height of nearly 3 meters, and an approximate body mass of 2 to 2.5 tons. It had a slender body compared to other more robust tyrannosaurids like \u003cspan class=\"hover:entity-accent entity-underline inline cursor-pointer align-baseline\"\u003e\u003cspan class=\"whitespace-normal\"\u003eTyrannosaurus rex\u003c\/span\u003e\u003c\/span\u003e, suggesting greater cursorial capabilities and a predatory strategy based on relative speed.\u003c\/p\u003e\n\u003cp data-end=\"1566\" data-start=\"947\"\u003eThe skull was large and elongated, with lengths that could exceed 1 meter. It was equipped with powerful jaws armed with ziphodont teeth, laterally compressed, recurved, and with serrated edges, adapted for cutting meat and tearing tissues. The maxillary and dentary teeth showed variation in size and shape (heterodonty), optimizing different functions during feeding. The eye sockets were relatively large, suggesting good visual capacity, while the cranial fenestrae helped lighten the skull's weight without compromising its structural strength.\u003c\/p\u003e\n\u003cp data-end=\"2156\" data-start=\"1568\"\u003eIn terms of postcranial morphometry, the hind limbs were long and muscular, with well-developed tibiae and metatarsals, indicating efficient and relatively fast bipedal locomotion. The foot was functionally tridactyl, with the central toe as the main weight-bearing digit. In contrast, the forelimbs were greatly reduced, with only two functional digits equipped with claws, a typical characteristic of tyrannosaurids. The tail was long and rigid, acting as a dynamic counterweight for the body and facilitating balance during locomotion.\u003c\/p\u003e\n\u003cp data-end=\"2674\" data-start=\"2158\"\u003eThe axial skeleton features vertebrae with pneumatic structures (air-filled cavities), which reduced body weight and improved locomotor efficiency. The musculature associated with the skull and neck was powerful, allowing for significant bite forces, although probably less than those of \u003cem data-end=\"2494\" data-start=\"2475\"\u003eTyrannosaurus rex\u003c\/em\u003e. Biomechanical studies suggest that its predatory strategy may have included rapid attacks aimed at relatively agile prey, such as hadrosaurids and juvenile ceratopsians.\u003c\/p\u003e\n\u003cp data-end=\"2984\" data=\"2676\"\u003eEcologically, \u003cem data-end=\"2714\" data-start=\"2692\"\u003eGorgosaurus libratus\u003c\/em\u003e occupied the apex or sub-apex predator niche in Late Cretaceous ecosystems.
