Resumen

ALBERDI, MARÍA TERESA et al. Late Pleistocene Hippidion saldiasi Roth, 1899 (Mammalia, Perissodactyla) from Calama, northern Chile. Rev. chil. hist. nat. [online]. 2007, vol.80, n.2, pp. 157-171. ISSN 0716-078X.  http://dx.doi.org/10.4067/S0716-078X2007000200003.

This paper describes the Hippidion bones recovered from the Atacama Desert (Calama, Second Region of Chile). The analyzed assemblage corresponds to a nearly complete skeleton from Betecsa 1 site and more poorly preserved remains from Kamac Mayu site. In both H. saldiasi is identified. Two ¹⁴C radiometric determinations indicate late Pleistocene age for these remains (21,070 ± 100 BP and 21,380 ± 100 BP). Environmental and diet inferences from stable isotope analysis are also presented. The δ¹³C value from Betecsa 1 horses (-15.45 from bone sample and -16.68 from enamel sample) suggest a dietary adaptation exclusively C₃ feeders. This is the first skull and associated skeleton recovered of this species
