Resumen
El análisis tafonómico permite conocer el origen y las posibles causas de la preservación diferencial en restos óseos. Este conocimiento resulta de suma utilidad para abordar análisis bioarqueológicos, ya que proporciona información clave sobre los procesos de formación del registro bioantropológico y de las condiciones ambientales del pasado. Este trabajo se centra en el estudio de los procesos y agentes post-depósitacionales de origen no antrópico que actuaron en el sitio Médano Petroquímica, un sitio con entierros prehispánicos (entre 419 ± 46 AP y 363 ± 45 AP) ubicado al sudoeste de la provincia de La Pampa, Argentina. Se realizaron análisis tafonómicos en restos óseos humanos correspondientes a 19 individuos recuperados de un entierro primario simple y tres entierros secundarios múltiples. Se contabilizaron 4179 especímenes correspondientes a 1829 elementos. Los resultados muestran que los entierros múltiples fueron afectados de manera similar por las distintas variables consideradas. Aunque la meteorización fue la variable registrada con mayor frecuencia, la acción de raíces habría sido la que mayormente afectó la integridad de los elementos. Esta experiencia pretende destacar la importancia del análisis tafonómico en los entierros humanos para obtener información acerca de la influencia del ambiente en el registro bioarqueológico.
Taphonomic analysis allows knowing the origin and the possible causes of the differential preservation in bone remains. This knowledge is very useful for approaching bioarchaeological analyzes, as it provides key information on the processes of formation of the bioanthropological record and the environmental conditions of the past. This work focuses on the study of post-depositional processes and agents of non-anthropogenic origin that affected the Médano Petroquímica site, a pre-Hispanic hunter-gatherer cemetery (between 419 ± 46 BP and 363± 45 BP) located in the southwest of the province of La Pampa, Argentina. Taphonomic analyzes were performed on human skeletal remains corresponding to 19 individuals recovered from a single primary burial and three multiple secondary burials. 4179 specimens corresponding to 1829 elements were counted. The results show that multiple burials were similarly affected by the variables considered. Although weathering was the most frequently recorded variable, the action of roots would have had the greatest impact on the integrity of the elements. This experience aims to highlight the importance of taphonomic analysis in human burials to obtain information about the environmental influence on the bioarchaeological record.
