Argyrodyptes microtarsus Ameghino, 1905: a shearwater (Procellariiformes) from the Eocene-Oligocene of Argentina. In the present note the systematic position of the problematic genus and species Argyrodyptes microtarsus is discussed. This taxon comes from Eocene-Oligocene beds of the San Juli?n Formation, Chubut Province, Argentina. Argyrodyptes is a valid genus of the family Procellariidae, and appears to be closely related to Puffinus. If its familiar assignment is correct, Argyrodyptes represents one of the oldest record for the family.
En el presente trabajo se discute y revisa la posici?n sistem?tica del problem?tico g?nero y especie Argyrodyptes microtarsus. Este tax?n proviene de capas eo-oligocenas de la Formaci?n San Juli?n, Provincia de Chubut, Argentina. Argyrodyptes es un g?nero v?lido de la familia Procellariidae, y parece encontrarse cercanamente relacionado con Puffinus. Si su asignaci?n familiar es correcta, Argyrodyptes representar?a uno de los registros m?s antiguos de la familia.
