La ictiofauna del Holoceno Inicial y Medio de Portugal: Implicaciones tafonómicas, ecológicas y culturales

Abstract

El presente estudio proporciona nuevos datos sobre la ictiofauna de inicio-mediados del Holoceno en Portugal. Los resultados obtenidos con el análisis de 5082 restos de peces recuperados en ocho yacimientos arqueológicos, son comparados con otros obtenidos por otros autores. El análisis ictioarqueológico explora la representación relativa de los diferentes tipos de peces en los yacimientos, los elementos esqueléticos representados, los tamaños individuales, restos tecnológicos presumiblemente asociados a la pesca, y otros elementos que permitan identificar la estacionalidad y los métodos de obtención del recurso que son los peces. A este efecto también son abordadas cuestiones tafonómicas y metodológicas, relacionados con la preservación y la recuperación del material. El análisis tafonómico sugiere que la gran mayoría de los taxones representados han sido capturados para consumo humano. Los taxones identificados revelan la explotación de una importante diversidad de recursos marinos-estuarinos. Estos sugieren condiciones ecológicas comparables a lo largo de la secuencia temporal analizada, y utilización de métodos de pesca semejantes en las regiones estudiadas. Las diferencias existentes lo son respecto a las frecuencias relativas de los taxones/grupos de taxones más abundantes, hecho que puede relacionarse con eventuales diferencias en la fauna local y/o época de captura Desde un punto de vista metodológico este trabajo proporciona un método para reconstituir las tallas de corvina (Argyrosomus regius) a partir de sus vértebras y otolitos. El método implica el cálculo de ecuaciones de regresión a partir de las medidas tomadas de 36 equeletos y 113 otólitos (sagitta) de corvina, y permite pronosticar simultáneamente el tamaño individual y el número mínimo de individuos (NMI) a partir de los elementos recuperados en yacimientos arqueológicos. Los resultados muestran que el tamaño individual de la especie puede ser calculado con precisión (r2 range: 0.921-0.992). Las ecuaciones obtenidas han sido utilizadas para analizar la variación de tamaños y NMI de corvina en los yacimientos analizados. Los resultados obtenidos en esta obra pueden ser comparados con futuros resultados alcanzados (i.e. isotopos estables y esqueletocronología) a partir del análisis de materiales recuperados en contextos arqueológicos de la Península Ibérica

This study provides new data concerning fish remains from the Portuguese early-mid Holocene. It includes the examination of 5082 fish bones from eight archaeological sites in Portugal, and their comparison to another three samples previously analyzed in literature. Looking at the fish bone record, this study scrutinizes the relative representation of the different types of fish at various sites, the skeletal elements present, the sizes of the fish, and any associated technological remains in order to identify the seasonality and methods of procurement for this resource. Taphonomical and methodological issues related to preservation and recovery are also addressed. Taphonomical analysis suggests that most taxa were caught for human use/consumption. The identified taxa disclose an important diversity of marine-estuarine resources. The list suggests comparable ecological conditions along the temporal sequence analyzed, abundance of the dominant taxa, and use of similar fishing methods in the regions studied. Some existing differences concern the relative frequencies of taxa / groups most abundant taxa, possibly related to variances in local wildlife and / or time of capture. From a methodological standpoint, this study presents a method for predicting meagre (Argyrosomus regius) body size from otoliths and vertebrae recovered from archaeological sites. The method involves regression equations calculated from a reference collection of 36 meagre skeletons and 113 meagre otoliths (sagitta) and allows the simultaneous estimation of original body size and minimum number of individuals (MNI) from archaeological bone structures. The results show that the original body size of meagre can be accurately predicted from many bone measurements (r2 range: 0.921-0.992). These regressions are used in the assessment of size variation and MNI of meagre from the sites analyzed. The data generated provide a solid base for comparison and interpretation of future results (e.g. isotope, sclerochonology) from contemporary sites in Iberia
