Sumario:The study of micromammals contained in raptor pellets is a useful tool to evaluate mechanisms of accumulation of archaeofaunal records, as well as to strengthen palaeoenvironmental inferences. Whit the aim of increase the knowledge about possible accumulating agents of micromammal remains in archaeological and paleontological contexts, this work presents the first taphonomic study of bone and tooth remains recovered from Megascops choliba pellets in the mountain Chaco of the northwest of the province of Córdoba, Argentina. The samples include eight species of sigmodontine rodents and one species of Thylamyini marsupial. The taxonomic profile of the prey, abundance and proportions of anatomical elements, breakage patterns and evidence of digestion were analyzed. The taphonomic evaluations indicated a high percentage of relative abundance of skeletal parts, with a preponderance of postcranial elements over the cranial ones, and a slight loss of distal elements with respect to the proximal ones. Regarding the fracture patterns, although a high proportion of cranial elements were detected fractured, the postcranial elements generally recovered complete. Finally, a high proportion of teeth was detected altered by light digestive action. These observations would reveal the inclusion of M. choliba in the categories of moderate to intermediate modification.
