We present in this work a new mammal bed from the Miocene Duero basin. The bed is placed in Bolaños de Campos (Valladolid province, Castilla y León, Spain) in which a rhioceros fossil rest has been found. The bed is located in a thin conglomerate-sandstone layer within the so called Tierra de Campos unit (mid Aragonian-early Vallesian). We describe a jaw fragment of Lartetotherium sansaniense (Rhinocerotidae, Perissodactyla, Mammalia) belonging to a young individual. The presence of this species actually corresponds with the upper Aragonian age (MN 7/8) formerly attributted to the Tierra de Campos unit where the mammal bed is located.
