Resumen:
The Trelew Member of the Sarmiento Formation (early Miocene) at Gaiman, Chubut province, Argentina, is one of the most prolific South American Cenozoic localities for squamatan remains. Within the lizards, at least three teiids have been cited, but the material has never been described. In this paper, mainly fragmentary dentaries and maxillae from this site are identified as belonging to the genus Tupinambis. These constitute the earliest record of this extant teiid genus. Tupinambis has a wide range of distribution through South America but is presently absent in the Gaiman area. Its occurrence in the early Miocene of Patagonia indicates warmer and more humid climatic conditions than today.
