The carnivore guild was represented by several extinct taxa such as the sabretooth cat Smilodonthe Patagonian Panther Panthera onca mesembrinaa short-faced bear Arctotherium tarijense and a large fox Dusicyon avusbut also by the extant puma Puma concolor.

In order to reconstruct the relation- ships within the predator guild and between these carnivores and their potential prey, body size, prey size and diet habits of each predator were estimated. These results are complemented with stable iso- topic analyses and taphonomic information. Results indicate that the guild was composed of three felids that were large hypercarnivores, two of which Smilodon, P. Morphology suggests that the short-faced bear was mainly an omnivore that may have scavenged and occasionally hunted medium-large mammals like camelids and horses.

Stable isotopes d13C and d15N are congruent with these in- terpretations, although they indicate that Arctotherium and D. This could be explained by scavenging habits. Stable isotopes also indicate that P. Taphonomic studies showed that P. The diversity of potential prey is lower than that observed in lower latitudes e. All rights reserved.
