This paper tries to amplify the information about the poorly known fossil beaver Dipoides problematicus (Schlosser, 1902). This species has been found in several localities near the Mio-Pliocene boundary of the Granada Basin (southern Spain). During that time span, beavers are very scarce in southern Spain, but abundant in the Teruel region (northern Spain). Since they have specific ecological preferences, their presence in the Granada Basin and their absence in other southern Spanish basins have paleobiogeographical and paleoecological consequences.
