The american alligator (Alligator mississipiensis): a new model for investigating developmental mechanisms in normal and abnormal palate formation

Despite numerous investigations, there are still many unsolved problems concerning normal and abnormal palatal development. The American Alligator is here put forward as a new model for the investigation of a variety of developmental phenomena associated with palatogenesis. The structure of the palate of the adult Alligator is reported. This animal exhibits a unique combination of reptilian and mammalian features in its craniofacial anatomy and so its craniofacial development should be of considerable interest.
