NUEVOS RESTOS DE RHAMPHOSTOMOPSIS NEOGAEUS (BURM.) RUSCONI 1933, (REPTILIA, CROCODILIA) DEL "MESOPOTAMIENSE" (PLIOCENO MEDIO - SUPERIOR) DE ARGENTINA

Zulma B. Gasparini

Abstract


Two specimens of Rbampbostomopsis neogaeus are studied, one of which is a relatively complete associated skull and mandible of one individual. The comparisons made with different extinct and living gavials prove that this pliocene species is a true gavialidae. This is a new evidence of the presence of the Gavialidae during the Tertiary of South America. Furthermore, this species proves that during the Pliocene this peculiar Crocodilia ranged as far south as 32° lat. The peculiar disyunctive distribution of the known gavials is a tantalizing problem.
