Abstract

Fossiliferous middle Pleistocene sediments of the Tarija basin of southern Bolivia contain a classic Ensenandan land-mammal fauna. New carbon isotopic data reported here for 5 specimens of the grazing mammals Equus (horse) and Cuvieronius (mastodon), documented from 8 stratigraphic levels at Tarija, vary significantly in the C 13 values of their teeth. These new isotopic data are used here to identify warm-cold paleoclimatic cycles during the middle Pleistocene and clarify the upper limit for the Ensenadan land-mammal age
