Extremitätenreste einer Mönchsrobbe (Phocidae,Carnivora, Mammalia) aus dem Miozän von Bocholt (Niederrhein)

From the Reinbekian deposits of Bocholt (Lower Rhine) a left femur and the distal fragment of a left tibia are described. A comparison with known fossil specimens results no direct conformity. The morphological relationship of the limb bones is nearest to the Monachinae. They are introduced with the termMonotherium sp. Due to their stratigraphical age, in comparison to younger relations, they own some primitive features.
