Review of feeding ecology data of Late Pleistocene mammalian herbivores from South America and discussions on niche differentiation

The present contribution provides a review of the feeding paleoecology studies based on carbon isotopic data available for 13 extinct megamammals that existed in South America during the Late Pleistocene. These ancient feed ecology data were grouped into four geographic ecoregions, supplying the basis for an analysis of the interspecific interactions within a mammal assembly, based on the classification of taxa in three trophic guilds — grazers, browsers, and mixed-feeders.
