  1. Samples with the same "specimen number" correspond to the same individuals. The bones correspond to the mandibular or maxillary remains that contained the teeth that were analyzed. Plio = Pliocene; Pl = Pleistocene; e = enamel; d = dentine; b = bone; t = tooth (enamel + dentine). Ar = Argentina; Bo = Bolivia; Br = Brazil; Ch = Chile. A = Andean; PL = Plain landscape. 1Taken from MacFadden et al. [22], 2taken from MacFadden and Shockey [27] and 3taken from MacFadden et al. [20].
