A FOSSIL SPECIMEN OF THE LONG-NOSED SNAKE RHINOCHEILUS FROM THE PLIOCENE OF SOUTHERN NEW MEXICO

摘要

This study reports a Blancan (late Pliocene) fossil snake from southern New Mexico. This is the first documentation of a late Cenozoic fossil snake from New Mexico and the first state fossil record of the genus Rhinocheilus. It also extends the western range of the known fossil distribution of Rhinocheilus and appears to represent the currently known most complete fossil specimen of the long-nosed snake.
