摘要：Tusks of very young mammoths and other proboscideans are extremely rare in the fossil record. This article presents all deciduous tusks and newly-developing permanent tusks of woolly mammoths which are known from Dutch localities and the North Sea. Four deciduous tusks are from The Netherlands and one is from Germany. Five specimens of newly-developing permanent tusks are also discussed. In this article, we present several characteristics and details of those tusks such as presence/absence of roots, and cementum and enamel layers that should facilitate an identification when new findings are made. We also describe a dental element, a digitelle, that is easily mistaken for a tusk of a juvenile woolly mammoth.
