Paleoecologia isotópica (δ13C, δ18O) de mamíferos do Pleistoceno final–Holoceno de Ituaçu, Bahia, Brasil

Isotopic paleoecology (δ13c, δ18o) of mammals from the late Pleistocene–Holocene Ituaçu, Bahia, Brazil. In this paper, isotopic (δ13C, δ18O) fossils Alouatta sp., Cebus Myocastor coypus, Dicotyles tajacu, Tamandua tetradactyla, and Tapirus terrestris collected in Lapa do Bode cave, Ituaçu Municipality, State is described. Radiocarbon ages 6,480–6,653 Cal yr. BP (14C collagen = 5,790±25 years) were obtained for T. tetradactyla 27,798–28,221 23,950±50 M. coypus. The herbivore taxa (T. terrestris, δ13C -14.9 ‰; -13.0 -12.7 ‰) had a diet composed mainly C3 plants (piC3< 80%), indicating forested environment, similar interpretation also suggested other that ingested >60% such as sp. (δ13C -13.1 ‰); D. tajacu -9.7 -11.0 ‰), allowing to suggest these lived low-density forests arboreal savanna habitats. Keywords: caves, paleodiet, carbon isotopes, oxygen isotopes.
