The Cretaceous alligatoroids share endocranial features, such as a posteroventral neurovascular projection of the labiolateral canal that connects to the groove\u2010like recess at the posterior edge of the maxilla and a paratympanic sinus system most similar to those of small\u2010bodied and young extant crocodylians, suggesting that these pedomorphic features may reflect the ancestral crocodylian condition.
