The sediments, collected from four areas within the cave and sieved-washed with fine wire meshes, contain microvertebrate remains of fish, frogs, lizards, birds and mammals, of which the latter are most

These methods are generally used at human occupation sites, but are not often employed at paleontological or mixed human-carnivore sites. At the site of Bois Roche, an Upper Pleistocene hyena den, we have used these meticulous recovery techniques in combination with absolute dating, geoarchaeological observations, taphonomic analyses, studies of microvertebrates and pollen analysis. Correlation of the site environmental data from pollen and microvertebrate assemblages with the vegetation record of a deep-sea core taken in the Bay of Biscay have allowed us to constrain the ages provided by ESR dating of bovid teeth and to reconstruct the physical environment of the site with a degree of confidence rarely achieved by the use of fossil remains from archaeological sites alone. Prior to our excavations, the site was interpreted as containing a mixed assemblage with evidence of hyena activities and human occupation in situ. Quantitative analysis of the small organic components present in large quantities in the sediments (deciduous hyena teeth, coprolite fragments, digested small bone fragments) prove, more than all other lines of evidence, that hyenas were in residence at Bois Roche, thus providing diagnostic criteria for distinguishing between occasional visitors and the main inhabitants of mixed human-carnivore sites. The analytical procedures presented in this paper have a value beyond the significance of the Bois Roche site because they can be applied to other sites.

Trinchera Dolina yields western Europe’s oldest fossil hominin, the 850 ka Homo antecessor; and at Sima de los Huesos there occurs the best collection of the Middle Pleistocene hominin Homo heidelbergensis. However, small mammals (Rodentia, Insectivora, Chiroptera and Lagomorpha) represent the largest number of species and greatest fossil abundance in the deposits of the Atapuerca cave complex. The small mammals are grouped by habitat categories, but because the ecology of mammals is complex, we base our study on the evolution of these categories throughout the sequence. The assemblage distribution at the Trinchera Dolina site reflects landscape and environmental changes during the past million years. Shifts between woodland, open land and moorland are indicated by the relative abundance of species based on diagnostic elements such as first lower molars. These data are comb...
