We report new occurrence records of Puma yagouaroundi (É. Geoffroy, 1803), a widely distributed but little known Neotropical carnivore, obtained over the last 10 years in Buenos Aires province, central Argentina. The records were collected by camera trapping surveys (n = 384 stations) and 195 interviews with local inhabitants. Our results improve our understanding of this species’ geographic range, especially its southernmost limit, and abundance, and confirm the need for more detailed studies to better assess the conservation status of this species in central Argentina and other parts of its range.

This paper aims to characterise the modifications caused by the Pampas fox (Lycalopex gymnocercus) to the bones and teeth of its prey in the Espinal and Dry Chaco environments, in central Argentina. Plant remains, invertebrate remains, and vertebrate bones and teeth were recovered from a set of more than 180 faeces. From an actualistic perspective, we evaluated the taphonomic signature of this predator in the remains of snakes, birds and mammals recovered in its faeces. We achieved a high rate of taxonomical identification and recovered remains of exotic and native fauna, such as Ovis aries and Lagostomus maximus, respectively. The most remarkable aspects recorded in this taphonomic study were a high frequency of breakage, a low frequency of tooth marks (only observed in large prey), and a high frequency and intensity of digestion damage. The information generated in this study contributes to the evaluations of accumulating agents in archaeological and palaeontological sites of South America.
