“…Taphonomic studies on recent accumulations produced by different predators may contribute to establish diagnostic characteristics of the fossil record (Andrews, 1990), and to determine if the bones in the site are present there due to the action of human beings or the action of carnivores. Therefore, some of the predators that inhabit central Argentina have already been evaluated in terms of the taphonomic changes they produce, including mammals such as the puma (Puma concolor), the hog-nosed skunk (Conepatus chinga) and the grey fox (Lycalopex griseus), as well as some raptor birds (Martín and Borrero, 1997;Gómez, 2005;Gómez and Kauffmann, 2007;Montalvo et al, 2007Montalvo et al, , 2008; Mondini and Muñoz, 2008;Tallade, 2009, 2010).
