New Cretaceous lungish material from southern South America, Argentina
Keywords:
Dipnoi, Gondwana, Santonian, skullAbstract
Dipnoi is a large group of sarcopterygians which ranges from the Early Devonian to the present. Traditionally, it was considered that their taxonomic diversity decreased at the end of Paleozoic. Dipnoans are abundant in the fossil record and their preservation state varies. The material study herein was collected in La Invernada locality, at 50 km southwest from the Rincón de los Sauces city, Neuquén Province, Argentina. We present the irst dipnoan skull record from the Mesozoic of South America and gives a preliminary description of the material. The new specimens have been identiied as a Ceratodontidae indet.
