The Family Abelisauridae is well-represented in which ancient landmass during the Late Cretaceous?
Answer
Gondwana
The Family Abelisauridae, to which *Xenotarsosaurus* belongs, is strongly associated with the fossil record originating from the ancient southern supercontinent known as Gondwana. During the Late Cretaceous period, this family flourished and dominated the ecological roles of apex predators across these southern landmasses. This geographical dominance contrasts sharply with the ecological roles occupied by tyrannosaurs, which held sway in the northern regions concurrently, illustrating a pattern of parallel evolution on separate continents.
