Abstract |
We describe the first authenticated fossil record for the family Amiidae in Argentina. The specimen consists on an isolated dentary coming from the Uppermost Cretaceous Allen Formation, from Río Negro province, Patagonia, Argentina, and belonging probably to the genus Amia. This specimen spans the biochronology of the Amiidae in South America, which were up to now restricted to Lower Cretaceous outcrops of Brazil. We also review the only previously reported amiid fish from the Neogene of South America. This single specimen consists of a dentary and some postcranial bones. It was originally named Pappichthys patagonica by Ameghino (1906). The study of this material allowed us to refer this species to the family Osteoglossidae, thus constituting the first fossil or extant record for the clade in Argentina. |
