Taphonomic study of Pleistocene mammals from Playa del Barco site (Pehuen Co) Buenos Aires Province, Argentina
Results are presented of a comparative taphonorruc study conducted on mammal remains from Playa del Barco, Buenos Aires Province, Argentina. Two bearing levels, belonging to a fluvial environment were recognized: one constituted mainly by conglomerates and the other by silty sandstones. The mammal r...

Results are presented of a comparative taphonorruc study conducted on mammal remains from Playa del Barco, Buenos Aires Province, Argentina. Two bearing levels, belonging to a fluvial environment were recognized: one constituted mainly by conglomerates and the other by silty sandstones. The mammal remains collected belong to the orders Xenarthra, Notoungulata, Litopterna, Rodentia, Carnivora, Perissodactyla, Artiodactyla, and Proboscidea, all of them components of the typical Pleistocene megafauna. When taking into account the source level, variations in the taphonomic attributes of the analysed materials were observed. Remains from the conglomerate show evidence of having been rapidly buried and then reelaborated before their final deposition.
