Palaeobiology, Palaeoecology and Systematics of the Crinoids in the Lower DevonianHunsrück Slate, Germany

下泥盆统Hunsrück板岩是世界上最重要的保护性矿床之一。化石发现的数量、它们出色的保存和物种多样性证明了这一评估的合理性，特别是在国际上。对于眼镜蛇来说尤其如此，它们是这里介绍的项目的重点。大量不同物种的完整发现是独一无二的，由于主要的黄铁矿化作用，保存允许对最精细的细节进行深入研究。棘皮动物甚至能够保存软组织也是众所周知的。对于这些调查，波恩大学地球科学研究所古生物系除其他外，有一台微型CT可供使用。除其他外，科学问题侧重于个体分类群或海百合群落的面部和生态依赖性、对以前不同生境的特殊形态适应以及发育和系统发育方面。由于化石材料在各个方面都得到了极好的保存，许多问题都只能被提出，而且可以有史以来第一次进行详细的研究。该项目将为重建约4亿年前一个生态复杂、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。

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.
