Which anatomical feature differentiated Xenotarsosaurus’s snout from that of Tyrannosaurs?
Answer
It featured a relatively short, deep snout
A key characteristic shared among Abelisaurids, the group to which *Xenotarsosaurus* belongs, is a snout that is relatively short and deep when contrasted with the morphology of Tyrannosaurs. Tyrannosaurs, such as those found in North America, were known for possessing long snouts. This difference in cranial structure—short and deep versus long—represents one of the fundamental anatomical distinctions between the dominant carnivorous lineages evolving on the separate Gondwanan and Laurasian continents during the Late Cretaceous.
