Mammalian remains from the North Sea. In the neighbourhood of the Brown Bank many fossil or subfossil bones are dredged from the bottom of the North Sea. Most bones have a weichselian age, but a few teeth of Mammuthus (Archidiskodon) meridionalis from the early Pleistocene have been met with. Also a number of bones of preboreal and boreal age have been found. These are dated by mesolithic bone implements. It is very difficult to distinguish the latter from the weichselian bones, so a number of species may have lived either in weichselian times or in mesolithic times or in both. A last fauna consists of bones of marine mammals which lived after the inundation of the North Sea.
