ABSTRACT
The fossil species Arrhinolemur scalabrinii, which was described from late Miocene deposits of Entre Ríos, Argentina, is reevaluated. Whereas the species was originally placed in the Primates (Mammalia) and later made the unique member of the order Arrhinolemuroidea within the Mammalia, our analysis indicates that the specimen is rather a fish of the genus Leporinus, family Anostomidae (Characiformes). The species is redescribed, and the characters that support its new generic assignment are discussed.
RESUMO
A espécie fóssil Arrhinolemur scalabrinii, descrita de depósitos do Mioceno Superior de Entre Ríos, Argentina, é reavaliada. Apesar da espécie ter sido originalmente incluída em Primata (Mammalia), constituindo-se posteriormente no único membro da ordem Arrhinolemuroidea dentro de Mammalia, nossa análise indica que o espécime trata-se de um peixe do gênero Leporinus, família Anostomidae (Characiformes). A espécie é redescrita, e os caracteres que fundamentam a nova posição do gênero são discutidos.
