Three unpublished fossil primate specimens from Patagonia (Argentina) are reported here. They are part of the Tournouër collection housed at the Muséum National d´Histoire Naturelle in Paris, France, and correspond to a partial mandible collected in 1902, and one upper deciduous premolar and one upper permanent molar collected in 1899. The partial mandible comes from the early Miocene sediments in the Coyle river area (Santa Cruz Province, Argentina), and is attributable to Homunculus patagonicus, adding that between the rivers Coyle and Gallegos several specimens assigned to Homunculus patagonicus were collected since the times of the Ameghino brothers. The remaining two dental specimens came from Colhué Huapi (Chubut province, Argentina), and both are here assigned to Mazzonicebus almendrae, the only known fossil primate in the early Miocene levels of Gran Barranca, Colhué Huapi area. This contribution provides new morphological information of the mandible and dentition of Homunculus, and the first evidence of the deciduous dentition of Mazzonicebus.
