Ten years of actualistic taphonomic research in the Pampas region of Argentina: Contributions to regional archaeology by Gutierrez, Maria Amelia, Rafuse, Daniel Joseph, Alvarez, María Clara, Massigoge, Agustina, Gonzalez, Mariela Edith, Scheifler, Nahuel Alberto, Kaufmann, Cristian Ariel

“…Our naturalistic observations include the development of taphonomic transects in different environments. Through this method, we were able to study different topics among which some of the more significant are the movement of bones by small-sized carnivores and the distribution of beached Magellanic penguin specimens along the coast. …”

Taphonomy of modern communal burrow systems of the Plains vizcacha (Lagostomus maximus, Chinchillidae) in the Pampas region of Argentina: implications for the fossil record by Rafuse, Daniel Joseph, Kaufmann, Cristian Ariel, Gutierrez, Maria Amelia, Gonzalez, Mariela Edith, Scheifler, Nahuel Alberto, Alvarez, María Clara, Massigoge, Agustina

“…Their burrowing activity and the accumulating habits, modifies the landscape, creating environments conducive to the buildup of objects and the reuse by different animals. These characteristics result in very complex associations of materials of different origins; making this rodent an important taphonomic agent with the potential to significantly impact the fossil record.…”

The role of the vizcacha (Lagostomus maximus) in the formation processes of archaeological sites from the Argentinian interhill plains by Bellinzoni, Jonathan, Kaufmann, Cristian Ariel, Álvarez, María Clara

“…The analysis of 21 vizcacheras showed that the vizcachas affect the archaeological record in different ways. Firstly, their digging activity alters stratigraphic sequences and generates associations of material of different chronology. …”

Differential Bone Survivorship and Ontogenetic Development in Guanaco (Lama guanicoe) by Gonzalez, Mariela Edith, Alvarez, María Clara, Massigoge, Agustina, Gutierrez, Maria Amelia, Kaufmann, Cristian Ariel

“…In the first place, density analysis was carried out from selected bones of modern individuals corresponding to different age classes. Secondly, two experimental designs were conducted to explore the responses of bones from animals of different ages to weathering and fluvial transport. …”

Taphonomic signature of Geoffroy's cat (Leopardus geoffroyi) on small sized preys: A comparative study of ingested and non-ingested leporid bones by Scheifler, Nahuel Alberto, Alvarez, María Clara, Rafuse, Daniel Joseph, Kaufmann, Cristian Ariel, Massigoge, Agustina, Gonzalez, Mariela Edith, Gutierrez, Maria Amelia

“…The taphonomic signature of Geoffroy's cat on ingested bones differs from the non-ingested sample. When evaluating both the ingested and non-ingested remains together the Geoffroy's cat bone modification pattern is characterized by a moderate average relative abundance of elements, a low percentage of tooth marks and a moderate percentage of digestive corrosion.…”
