Alligator munensis is an extinct species of alligator from the Quaternary of Thailand. After the skull of A. munensis was discovered, it was tentatively assigned to the Chinese alligator before being recognized as a distinct species. Although the two are still considered to be close relatives, the pronounced anatomical differences suggest that the two species split from one another long prior to the Pleistocene, possibly during the uplifting of the Tibetan Plateau during the Miocene. It had a short and robust skull and may have had globular back teeth possibly corresponding to a greater amount of hard-shelled prey items. The nostrils of A. munensis were positioned much further towards the back of the skull than in other alligators, but the function of this is unknown.[1]
