Tel. 6178032905 [email protected] (Received 24 May 2010; Revised and Accepted 22 June 2010) ABSTRACT: Distinguishing leporid bones accumulated by humans and other kind of predators becomes imperative to accurately understand human subsistence activities in the past, specially in the Iberian Peninsula and the Mediterranean region where these taxa are very abundant. Over the last years we have conducted several actualistic studies with modern leporid remains with the aim of identifying differences in the taphonomic signatures produced by competing preda- tors (i.e., humans, nocturnal or diurnal raptors and mammalian terrestrial carnivores). The pat- terns observed for each of these predators are now applied to the analysis of archaeological leporid remains from Mousterian layers of the Arbreda Cave site (North-East Iberia). The results obtained not only provide new data on Middle Palaeolithic small prey accumulations but also enable us to assess the methodological approach previously followed with modern samples.

En los últimos años hemos llevado a cabo diversos trabajos actualísticos con restos de lepóridos con la finali- dad de identificar diferencias entre los patrones tafonómicos característicos de los distintos tipos de depredadores (humanos, rapaces diurnas y nocturnas, y carnívoros terrestres). En este traba- jo los patrones observados para cada uno de estos depredadores se aplican al análisis de los res- tos arqueológicos de lepóridos del nivel musteriense I de la cueva de la Arbreda (Noreste de la Península Ibérica). Los resultados obtenidos no solo aportan nuevos datos sobre acumulaciones de pequeñas presas en el Paleolítico Medio sino que al mismo tiempo nos permiten evaluar la perspectiva metodológica desarrollada en el análisis de muestras actuales.
