Paleocene reptiles of Asia

Planocrania is an extinct genus of eusuchian crocodyliforms from what is now China. Two species are currently known to belong to the genus.

Protoalligator is an extinct genus of alligatoroid from the Paleocene Wanghudun Formation of China. It was first described as a species of Eoalligator in 1982 before being placed in its own genus in 2016. The name, which translates to "first alligator", was meant to carry on the same meaning as that of Eoalligator ("dawn alligator") as the latter was thought to be synonymous with another crocodilian by the team describing it. Recent studies have suggested that Protoalligator was part of an early radiation of alligatoroids endemic to Asia known as orientalosuchins, though not all studies agree
