Teeth of embryonic or hatchling sauropods from the Early Cretaceous (Berriasian) of Cherves-de-Cognac, France

The Cherves-de-Cognac site (Charente, France) has yielded a diverse continental microvertebrate fauna of Berriasian (earliest Cretaceous) age. Dinosaur remains are rare, but include three teeth that are referrable to an indeterminate sauropod, which might represent either a titanosauriform, a non-titanosauriform macronarian or a non-neosauropod. The small size of these teeth (with a maximum length of 3 mm, as preserved) and the almost complete absence of emanel wrinkling suggests that they pertained to embry-onic or hatchling individuals. The Cherves-de-Cognac sau-ropod represents a rare occurrence of sauropod embryos/ hatchlings, a new sauropod record from the poorly-known terrestrial Berriasian and another possible instance of the persistence of non-diplodocoid, non-titanosauriform sau-ropods into the Cretaceous.
