First record of Trogontherium cuvieri (Rodentia,Castoridae) from the Oosterschelde

A fragment of right tibio-fibula from the bed of the Oosterschelde deep channel is identified as Trogontherium cuvieri, not recorded previously from this area. The bone is larger than other material from Late Pliocene/ Early Pleistocene deposits in the Netherlands and the UK and falls within the size range of Middle Pleistocene material. Various interpretations are possible: size variation through time, sexual dimorphism (not previously recorded) or else the mixing of Middle Pleistocene material with the fauna from the Oosterschelde deep channel.
