A Late Pleistocene (MIS3) ungulate mammal assemblage (Los Rincones, Zaragoza, Spain) in the Eurosiberian-Mediterranean boundary

摘要

The Late Pleistocene archaeo-palaeontological sites in the Iberian Peninsula are located mainly on the coasts. Here, we present for the first time a palaeoenvironmental proxy for Upper Pleistocene locality (Marine Isotope Stage 3 MIS3) that is in the interior peninsular, in the Moncayo massif (Zaragoza). This is actually the boundary between Mediterranean and Eurosiberian climatic regions. This study is based in the site ungulates: Capra pyrenaica, which is larger in size than the current and fossil Capra from the Mediterranean area of the Iberian Peninsula. The horses have a small size, which is similar to that of the horses from Fontainhas and Casares. Significantly lesser in the number of specimens are the roe deer, the southern chamois and the auroch. The study and comparison of the faunal assemblage of the locality of Los Rincones with other sites of the Iberian MIS3 show a cluster of sites in the southern Peninsular, though separated, due to the abundance of Capra pyrenaica. The association of Los Rincones is similar to the southern peninsular sites such as Nerja, Gorham Cave, Cova Beneito and Zafarraya. The ungulate assemblage of Los Rincones represents a landscape with temperate climate, presence of steppe and patches of forest, similar to the current landscape surrounding the cavity today.
