Abstract
The present record from the white chalk of Holtug (Stevns Klint, Sjaelland) of the smali, distinctive phymosomatid echinoid Gauthieria altema (Kutscher, 1985) constitutes a notable addition to the latest Maastrichtian echinoid faunas in Denmark. Although both specimens available are crushed, preservation on the whole is better than the type material from the upper Lower Maastrichtian of Rugen (northeast Germany), and enables a more detailed description of the species, which was originally placed in Hemithylus Arnaud, 1896 but which is here transferred to the genus Gauthieria Lambert, 1888. One of the specimens preserves a single demipyramid and epiphysis of the lantern.
期刊介绍：
The Bulletin publishes contributions of international interest in all fields of geological sciences on results of new work on material from Denmark, the Faroes and Greenland. Contributions based on other material may also be submitted to the Bulletin if the subject is of relevance for the geology of the area of primary interest.
