| description |
The presence of native Arecaceae charred nuts has been widely reported in archaeological sites from eastern Uruguay. In such contexts, the recovery of these remains together with stone tools aimed at the obtention of the inner pulp (nutcrackers, locally known as “rompecoquitos” or “piedras con hoyuelos”) were interpreted as evidences of palm nuts processing by prehistoric inhabitants of the region. Native palm nuts, particularly from Butia, have been referred as a key subsistence resource for mound builders societies that occupied the area since middle Holocene. Nevertheless, the taxonomic attribution was not supported by any specific study on the matter. In this work we addressed the biometric chracteristics of the fruits of both native Arecaceae species, including seeds and endocarps. Experimental studies were also performed considering the mechanical fracture and flotation of natural and charred remains. Results showed that both palms exhibited distinctive eccentricity values as well as differential flotation and mechanical properties of endocarps and distinctive endocarp and seed mass values. These findings highlighted that palm nut remains from archaeological contexts can be identified with a high degree of confidence. |

La presencia de endocarpos carbonizados de Arecaceae nativas, Butia odorata y Syagrus romanzoffiana se ha reportado para diferentes sitios arqueológicos del Este del Uruguay. A nivel de los contextos arqueológicos, la recuperación de endocarpos carbonizados y de instrumentos conocidos como “rompecoquitos” o “piedras con hoyuelos”, da cuenta del procesamiento de los frutos de estas especies por parte de poblaciones prehistóricas que habitaron la región. Los frutos de palma, sobre todo de la especie Butia odorata, han sido referidos como uno de los recursos clave para la subsistencia de poblaciones constructoras de montículos (“cerritos de indios”) que ocuparon la región a partir del Holoceno medio. No obstante, no existen antecedentes de estudios específicos sobre la identificación taxonómica de los endocarpos de ambas palmas. En este trabajo se aborda la caracterización biométrica del fruto de las especies de Arecaceae a nivel de endocarpos y semillas. También se presentan estudios experimentales referidos a la fracturación mecánica de endocarpos sin carbonizar y flotación de restos naturales y carbonizados. Entre los resultados obtenidos se destacan los valores no solapados de excentricidad de endocarpos de ambas palmas, el comportamiento diferencial de fracturación y flotación y los valores distintivos de masa de endocarpos y semillas de ambas especies. Estos resultados demuestran el potencial de recuperación e identificación taxonómica de endocarpos en contextos arqueológicos de la región. A presença de endocarpos carbonizados de Arecaceae nativas, Butia odorata e Syagrus romanzoffiana foi relatada em diferentes sítios arqueológicos no leste do Uruguai. Ao nível dos contextos arqueológicos, a recuperação de endocarpos carbonizados e de instrumentos conhecidos como “cracker” ou “pedras onduladas”, explica o processamento dos frutos destas espécies por populações pré-históricas que habitavam a região. Os frutos da palma, especialmente os da espécie Butia odorata, têm sido referidos como um dos recursos-chave para a subsistência das populações de montículos (“cerritos de índios”) que ocuparam a região desde o Holoceno Médio. No entanto, não há histórico de estudos específicos sobre a identificação taxonômica dos endocarpos de ambas as palmas. Este trabalho aborda a caracterização biométrica do fruto da espécie Arecaceae ao nível do endocarpo e da semente. Também são apresentados estudos experimentais relativos à fratura mecânica de endocarpos não cicatrizados e flutuação de restos naturais e carbonizados. Dentre os resultados obtidos, destacam-se os valores não sobrepostos de excentricidade do endocarpo de ambas as palmas, o comportamento diferencial de fraturamento e flotação e os valores distintos de endocarpo e massa de sementes de ambas as espécies. Esses resultados demonstram o potencial de recuperação e identificação taxonômica de endocarpos em contextos arqueológicos da região. Facultad de Filosofía y Humanidades.
