Resumen de Los micromamíferos del tránsito Pleistoceno inferior-medio de Atapuerca (Burgos, España): Implicaciones bioestratigráficas y evolutivas.
The micromammals association of the TD5- TD6 levels is exclusive from the karstic complex of Atapuerca (Burgos, Spain). This association is characterized by the presence of arvicolids: Terricola gregaloides, Terricola huescarensis, Terricola subterraneus, Microtus brecciensis, Arvicola chalinei, Mimoniys savini, Pliomys episcopalis, together two new rodent species: Terricola seseae nov. sp. and Microtus lignani nov. sp.. This fauna seems to correspond to the transit Lower Pleistocene - Middle Pleistocene, with more than 780.000 years ago, near of Matuyama/ Brunhes boundary.
