A detailed analysis of pneumaticity of the sacrum and tail of Aoniraptor shows a complex structure within these vertebrae, being composed by small diverticulae surrounding large pNEumatic canals and a central chamber that opens outside through pleurocoels or pnematic canals.

It is suggested that isolated teeth originally referred as post-Cenomanian Carcharodontosauridae most probably belong to abelisaurids, and the development of horn-like structures and differential cranial thickening appear to be convergently acquired within Abelisauridae.

The occurrence of Masiakasaurus on Madagascar suggests that small-bodied abelisauroids, like their larger-bodied counterparts, were more cosmopolitan, radiating throughout much of Gondwana and paralleling the diversification of small coelurosaur theropods in Laurasia.
