Bioestratigrafía y evolución de Microtus brecciensis en los yacimientos del Pleistoceno de Atapuerca (Burgos, España)

Abstract

The stratìgraphic correlation and the chronometricals datums obtained in the levels from the karstic fillings of Atapuerca, enable us to see a paleontologie record of Microtus brecciensis since last episodes of Lower Pleistocene till the end of the Middle Pleistocene, and a evolutive trend to increase size through this time
