About Antecrocodylus

Antecrocodylus is a genus of crocodilian from the middle Miocene of Chiang Muan and Mae Moh, Thailand. The holotype consists of the back of the skull and an associated mandible. While far from complete and heavily damaged, the material highlights how little is known about the crocodylid fauna of Miocene Asia. Furthermore, Antecrocodylus was recovered as the basalmost member of Crocodylidae, having diverged before osteolaemines and crocodylines split from one another. This may suggest that it could provide significant information regarding the origins and evolution of modern crocodiles.
