What general anatomical traits characterize members of the Abelisauridae family?
Answer
Robust builds and deep skulls
The family Abelisauridae is known among paleontologists for a distinct suite of physical characteristics, which generally include a robust overall build and notably deep skulls. A striking feature often associated with this group, sometimes even exceeding what is seen in tyrannosaurids, is the presence of remarkably reduced or vestigial forelimbs. These anatomical specializations helped define their role as apex predators in the southern ecosystems during the Late Cretaceous.
