Abstract

The holotype of Hamadasuchus rebouli Buffetaut 1994 from the Kem Kem beds of Morocco (Late Albian – Cenomanian) consists of a left dentary which is limited, fragmentary and reconstructed in some areas. To aid in assessing if the original diagnosis can be considered as valid, the specimen was CT scanned for the first time. This is especially important to resolve the taxonomic status of certain specimens that have been assigned to Hamadasuchus rebouli since then. The reconstructed structures in this contribution are in agreement with the original description, notably in terms of alveolar count; thus the original diagnosis of this taxon remains valid and some specimens are not referable to H. rebouli anymore.
