摘要

这是一篇关于在斯瓦尔巴群岛发现的第一个新生代鲨鱼化石的简短报道。该标本来自古新世晚期grmantbyen组的绿色砂岩，该砂岩暴露于斯匹次卑尔根群岛Colesbukta西侧的Fossildalen。这颗牙齿属于古近系沙虎鲨属纹状鲨属，在其他极地地区也有发现。化石标本代表了最北端的古近纪鲨鱼记录，是斯匹次卑尔根新生代脊椎动物的第二具身体化石。

First shark record (Chondrichthyes, Elasmobranchii) from the Paleogene of Spitsbergen, Svalbard

This is a short report about the first Cenozoic shark fossil from Svalbard. The specimen derives from the late Paleocene greenish sandstone of the Grumantbyen Formation, which is exposed in Fossildalen on the western side of Colesbukta on Spitsbergen. The single tooth is assigned to the Paleogene sand tiger shark genus Striatolamia that also is known from other polar regions. The Fossildalen specimen represents the northernmost Paleogene shark record, and is the second reported body fossil of a vertebrate from the Cenozoic of Spitsbergen.
