Redescription of two lungfish (Sarcopterygii: Dipnoi) tooth plates from the Late Cretaceous Bauru Group, Brazil

Two lungfish tooth plates from the Adamantina and Marília formations, southeastern Brazil, are redescribed. One represents the youngest record of an asiatoceratodontid for Gondwana. This extends the upper temporal range of this family from Cenomanian to Turonian–Santonian. The other represents a new record of ceratodontids for South America. This discovery corroborates previous descriptions of South American fauna, such as the mixture of relict and ancient Gondwana taxa that disappeared by the end of the Cretaceous or the beginning of the Paleogene. The records add to the extant neotropical ichthyofauna, that survived after the South America–Africa separation.
