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Hunsrück板岩是世界上最重要的保护矿床之一。化石发现的数量，它们的杰出保护和物种多样性在国内，特别是在国际上证明了这一评估的合理性。这对于海百合来说尤其如此，这是这里介绍的项目的重点。不同物种的完整发现数量是独一无二的，由于主要的黄铁矿化作用，即使是最细微的细节也可以进行深入研究。即使是软组织的保存也是众所周知的。为了进行这些调查，波恩大学地球科学研究所古生物学系除其他外，拥有一台微型CT。科学问题的重点，除其他外，对个人分类群或海百合群落的面部和生态依赖性，特别形态适应以前不同的栖息地，以及发展和系统发育方面。由于化石材料在各个方面都得到了很好的保存，许多问题只有在第一次详细研究时才有可能提出。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。
