Lower third molar morphometrics and dietary implications in the archaeological cervid from Playa Don Bernardo archaeological site, Panamá

This study presents an osteometric analysis of the lower third molar (m3) from an archaeological cervid recovered from the Playa Don Bernardo (PdB) archaeological site on Pedro González Island, part of Panama’s Pearl Islands, dating to approximately 5000 BP. A total of 176 m3 specimens from both mod...

description This study presents an osteometric analysis of the lower third molar (m3) from an archaeological cervid recovered from the Playa Don Bernardo (PdB) archaeological site on Pedro González Island, part of Panama’s Pearl Islands, dating to approximately 5000 BP. A total of 176 m3 specimens from both modern and archaeological cervids were examined, including 26 teeth from PdB and comparative samples from Odocoileus virginianus, Odocoileus hemionus, Hippocamelus antisensis, Hippocamelus bisulcus, Ozotoceros bezoarticus, Blastocerus dichotomus, Mazama americana, Mazama bricenii, Mazama nana, Mazama temama, Subulo gouazoubira, Passalites nemorivagus, Pudu mephistopheles, and Pudu puda housed in several natural history museums. Morphometric analyses, including Principal Components Analysis (PCA) and boxplots, reveal that PdB does not fully overlap with any extant species but occupies an intermediate morphospace between small-bodied taxa (Pudu spp.) and medium-sized deer (Mazama americana, Subulo gouazoubira, and Passalites nemorivagus). PdB specimens display considerable intraspecific variation, yet consistently exhibit larger values than Pudu and smaller than larger-bodied taxa such as Hippocamelus antisensis and Odocoileus hemionus. The m3 proportions suggest a mixed-feeding strategy, indicating adaptation to a mosaic environment of open woodlands and semi-forested areas.

Este estudio presenta un análisis osteométrico del tercer molar inferior (m3) de un cérvido arqueológico recuperado en el sitio arqueológico Playa Don Bernardo (PdB), en la isla Pedro González, parte del Archipiélago de las Perlas, Panamá, con una antigüedad aproximada de 5000 años AP. Se analizaron un total de 176 especímenes de m3 de cérvidos modernos y arqueológicos, incluyendo 26 dientes de PdB y muestras comparativas de Odocoileus virginianus, Odocoileus hemionus, Hippocamelus antisensis, Hippocamelus bisulcus, Ozotoceros bezoarticus, Blastocerus dichotomus, Mazama americana, Mazama bricenii, Mazama nana, Mazama temama, Subulo gouazoubira, Passalites nemorivagus, Pudu mephistopheles y Pudu puda, conservadas en varias colecciones de historia natural. Los análisis morfométricos, incluyendo un análisis de componentes principales (PCA) y diagramas de caja, revelan que PdB no se solapa completamente con ninguna especie actual, sino que ocupa un morfoespacio intermedio entre los cérvidos pequeños (Pudu spp.) y los medianos (Mazama americana, Subulo gouazoubira y Passalites nemorivagus). Los especímenes de PdB muestran una variabilidad intraespecífica considerable, pero sus valores son consistentemente mayores que los de Pudu y menores que los de cérvidos de mayor tamaño como Hippocamelus antisensis y Odocoileus hemionus. Las proporciones del m3 sugieren una estrategia de alimentación mixta, indicando una adaptación a un entorno en mosaico de bosques abiertos y áreas semi-forestadas. El contexto insular y la presencia de actividad humana temprana, incluyendo el cultivo de maíz (Zea mays), sugieren posibles influencias antrópicas en el uso del hábitat y el comportamiento forrajero de PdB. La ausencia de un análogo moderno directo plantea la posibilidad de que PdB represente una población insular extinta con adaptaciones ecológicas únicas. Este estudio contribuye a la comprensión de las interacciones humano-fauna y las dinámicas paleoecológicas en entornos insulares del trópico centroamericano durante el Holoceno medio. Este estudo apresenta uma análise osteométrica do terceiro molar inferior (m3) de um cervídeo arqueológico recuperado do sítio arqueológico Playa Don Bernardo (PdB), na Ilha Pedro González, parte do Arquipélago das Perlas, no Panamá, datando de aproximadamente 5000 a.C. Um total de 176 espécimes de m3 de cervídeos modernos e arqueológicos foram examinados, incluindo 26 dentes de PdB e amostras comparativas de Odocoileus virginianus, Odocoileus hemionus, Hippocamelus antisensis, Hippocamelus bisulcus, Ozotoceros bezoarticus, Blastocerus dichotomus, Mazama americana, Mazama bricenii, Mazama nana, Mazama temama, Subulo gouazoubira, Passalites nemorivagus, Pudu mephistopheles e Pudu puda, provenientes de vários museus de história natural. As análises morfométricas, incluindo a Análise de Componentes Principais (PCA) e gráficos de caixa, revelam que o PdB não se sobrepõe completamente a nenhuma espécie existente, mas ocupa um espaço morfológico intermediário entre táxons de pequeno porte (Pudu spp.) e cervos de porte médio (Mazama americana, Subulo gouazoubira e Passalites nemorivagus). Os espécimes de PdB exibem uma variação intraespecífica considerável, mas consistentemente apresentam valores maiores do que Pudu e menores do que táxons de maior porte, como Hippocamelus antisensis e Odocoileus hemionus. As proporções do m3 sugerem uma estratégia de alimentação mista, indicando adaptação a um ambiente mosaico de bosques abertos e áreas semi-florestadas. Centro de Estudios Históricos.
