The Lower Devonian Hunsrück slate is one of the world's most important conservation deposits. The number of fossil finds, their outstanding preservation and species diversity have justified this assessment nationally and especially internationally. This is particularly true for the crinoids, which are in the focus of the project presented here. The sheer number of complete finds of different species is unique and the preservation allows in-depth studies of even the finest details due to the predominant pyritisation. Even the preservation of soft tissue is known for the echinoderms. For these investigations, the Department of Palaeontology of the Institute of Geosciences at the University of Bonn has, among other things, a micro-CT at its disposal. The scientific questions focus, among other things, on the facial and ecological dependencies of the individual taxa or of crinoid communities, special morphological adaptations to formerly different habitats as well as developmental and phylogenetic aspects. Many of the questions are only possible to ask due to the excellent preservation of the fossil material in every respect and can be studied in detail for the first time ever. The project will make a significant contribution to the reconstruction of an ecologically complex, species-rich marine biocoenosis about 400 million years ago, in which crinoids played a central role.

下泥盆统洪斯吕克板岩是世界上最重要的保护矿床之一，其化石发现的数量、其出色的保存和物种多样性在国内尤其是国际上证明了这一评估的合理性。这里展示的不同物种的完整发现数量之多是独一无二的，由于主要的黄化作用，保存甚至可以对最细微的细节进行深入研究，甚至软组织的保存也以对于这些研究，波恩大学地球科学研究所古生物学系拥有一台微型 CT，其中的科学问题主要集中在棘皮动物的面部和生态依赖性上。单个类群或海百合群落、对以前不同栖息地的特殊形态适应以及发育和系统发育方面，许多问题只有在化石材料在各个方面都得到良好保存的情况下才能提出。该项目将为重建大约 4 亿年前生态复杂、物种丰富的海洋生物群落做出重大贡献，海百合在其中发挥了核心作用。
