This paper presents the results of the taphonomic analysis of the micromammal bone remains recovered from Nutria Mansa 1 (NM1), an archaeological site located in the Pampean plains, Argentina. This campsite was occupied by hunter-gatherers that processed and consumed Lama guanicoe during the Late Holocene. In NM1, there are taxa from different environments: mammals from arid and semiarid environments (Patagonic Phytogeographic Province) and humid and temperate environments (Pampean Phytogeographic Province). The main objective of the present study was to evaluate how the recorded small mammal species were incorporated into the archaeological site and which of them were exploited by humans. The micromammal assemblage shows traces of post mortem agents such as weathering, chemical action of sediments, and probably some evidence of predation. The micromammal bones in the archaeological record offer no clear evidence of human modification, and their presence can be the result of predation or other postdepositional agents such as the action of water on the flood plain.
