GOMEZ, Gustavo N.  y  MESSINEO, Pablo G.. Taphonomic Analysis Of Micro And Mesomammal Bones From Laguna La Barrancosa 1 Archaeological Site (District Of Benito Juárez, Buenos Aires Province). Intersecciones antropol. [online]. 2008, n.9, pp.71-91. ISSN 1850-373X.

In this paper, results are presented from quantitative and taphonomic analyses of micro and mesomammal bones recovered from Laguna La Barrancosa 1 archaeological site. The analytical methods used included macroscopic and microscopic (SEM) techniques. The rates used (pc/c y f+h/md+mx) show that there is a greater representation of cranial elements than postcranial due to diagenetical agents, which were the principal cause of the loss of some skeletal parts. These diagenetical agents, including the corrosion produced by roots and sedimentological conditions, were the principal agents of the cortical surface damage of the micro and mesomammal bones. There were no traces of digestion or other predators' marks indicating that the micromammal species were not incorporated into the archaeological record by a trophic chain. Also, there was no evidence of anthropic action on the micro and mesomammal bones (e.g., cut marks, burned bones, etc.). The evidence indicates that these species lived and died in situ. The caves recorded at the site and rodents' marks on Lama guanicoe bones indicate that these species acted as post-depositional modifying agents of the bone assemblages.
