Below is a dew claw (hallux) cast from Gorgosaurus. In the foot of this animal, this toe would have been turned inward , and was set up fairly high on the foot. This means that the hallux did not support the weight of the animal during the stride, though may have borne some weight when Gorgosaurus was standing up from a resting position.
Gorgosaurus is one of the best, if not the best, understood tyrannosaurs in the fossil record, due to the large number of skeletons that have been recovered. These bones give scientists insights regarding behavior, diet, and habitat. It shared its range with the more stoutly built Daspletosaurus, another tyrannosaur, but there’s little evidence that the two routinely came into conflict. It’s possible that the two favored different prey or different environments, with Gorgosaurus staying more to the north and Daspletosaurus restricting itself to a more southern range. Some tyrannosaurs, such as Albertosaurus, show evidence of group behavior, but no evidence for this has been found with Gorgosaurus.
There were a few smaller predators in Gorgosaurus’ environment, though no mid sized ones. It’s possible that young and subadult Gorgosaurus’ filled in the niche that would normally be occupied by other predators. If that’s the case, it would be evidence against cooperative behavior, as the juveniles and adults would be exploiting different food sources. Quite a few Gorgosaurus specimens show pathologies ranging from bite marks to fractures to a possible brain tumor. All of these indicate that Gorgosaurus lived the typical life for a predator: fast, brutal, and often all too short.
