Los pumas (Puma concolor) como agentes tafonómicos. Análisis actualístico de un sitio de matanza en los Andes de Mendoza, Argentina

A taphonomic study of the carcass of an adult guanaco (Lama guanicoe) recently killed and consumed by one or more pumas (Puma concolor) in the Laguna del Diamante reserve (Mendoza province, Argentina) is exposed, and the case is discussed in the light of the available taphonomic information on this agent in America. The carcass was dispersed along more than 30 m and basically devoid of soft tissues. Thirty-four percent of the bones presented tooth modifications, removal of bone tissue and edge damage, mostly attributable to pumas. Some of these modifications are considerable, as in the case of the skull. The results of the study suggest that bone modifications are intense as compared to other taphonomic studies on this felid. The implications of this are discussed, and the conclusion is reached that more knowledge is needed on the range of variation in puma taphonomic action and the conditions under which such variation occurs.     

La acción tafonómica de mamíferos carnívoros en el sitio arqueológico Inca Cueva-cueva 4, borde oriental de la Puna argentina

In this paper, a model of carnivore taphonomic action in the Argentinean Puna is applied to archaeological site Inca Cueva-cueva 4, on the Eastern Fringe of the Puna East of the Andes cordillera, which contains hunter-gatherer occupations dating to the early and middle Holocene. Different indicators, such as the low levels of bone modifications (ca. 2 to 8% NISP), consisting mainly in subtle marks, suggest a low intensity of the intervention of carnivores during the formation of these deposits. Variables such as the frequency of carnivore scats attest to repeated carnivore visits to the cave, but the “dilution effect” upon the small faunal assemblages these carnivores tend to accumulate in a context of larger zooarchaeological assemblages would have faded their traces away.
