摘要：
Mammal fossil remains from San Pedro (Buenos Aires Province, Argentina) are very poorly known. In this paper, best preserved specimens of Equidae and Gomphotheriidae are described. They come from "Campo Sposito" quarry near San Pedro city. The quarry was referred to Lujanian Age, Biozone of Equus (Amerhippus) neogeus. We conducted a comparative study with other South American horse and gomphothere remains, mainly from Argentina and Brazil, allow their identification as Equus (Amerhippus) neogeus, Hippidion principale and Stegomastodon cf. S. platensis. Two absolute dates were obtained by the method of OSL: 37626 +/- 4198 y 41554 +/- 3756 years BP. Based on this data the correlation with other localities we referred this bed to oxygen isotopic stage 3.
