Resumen:
ABSTRACT.?The first snake craniomandibular fossil specimen from the Campanian?
Maastrichtian of South America is described herein. The specimen, from the Allen
Formation in Río Negro province, consists of an incomplete anterior portion of a left
dentary. The general morphology of the bone resembles that of the basal legged snake
Najash Apesteguía and Zaher and the small madtsoiids from the Eocene?Miocene of
Australia. The dentary was found associated with several isolated snake vertebrae, most
of which are referable to madtsoiids and thus, it probably belongs to one of the already
known madtsoiid taxa.
known madtsoiid taxa.
