Abstract

A partial crocodilian skeleton, including a well-preserved skull and mandible, from the marine Lower Cenomanian of Normandy (northwestern France) is described as a new genus and species of the family Pholidosauridae (Mesosuchia), Oceanosuchus boecensis. Diagnosis for genus and species: Mesorostrine pholidosaurid (rostral index 66% as compared with 74% for Terminonaris robusta and 75% for Sarcosuchus imperator, hitherto the least longirostrine species in that family), relatively short mandibular symphysis (11 post-symphysial alveoli), no external mandibular fenestra, prearticular present, paired tuberosities at the base of the cervical vertebral centra.
