Abstract

Nine shark teeth were collected at Arnager in the south-western part of the island of Bornholm (Baltic Sea, Denmark). They all come from the basal conglomerate of the Coniacian (Upper Cretaceous) Arnager Limestone Formation and belong to the genus Ptychodus Agassiz, 1834. Three different species are dentified: P. altior, P. latissimus and P. mammillaris, which were hitherto unknown in Denmark.

Agassiz Ptychodus属新记录，1834，（软骨鱼类，Elasmobranchii），来自Bornholm（丹麦）上白垩纪

在Bornholm岛（丹麦波罗的海）西南部的Arnager采集了九颗鲨鱼牙齿。它们都来自科尼亚阶（上白垩纪）阿纳格石灰岩组的基底砾岩，属于Ptychodus Agassiz属，1834年。目前已鉴定出三种不同的物种：高山乳杆菌、阔背乳杆菌和长毛乳杆菌，它们在丹麦迄今尚不为人所知。
