项目摘要

The Lower Devonian Hunsrück Slate (Germany) is known for its unique fauna and flora and the high quality of the preservation of pyritiesed fossils. Especially the arthropods are highly diverse and remarkable for their preservation. Some of them are of unknown systematic affinity and ambiguous phylogenetic relationship. These morphologically very archaic taxa, like Vachonisia rogeri, Mimetaster hexagonalis, and Devonohexapodus bocksbergensis, are poorly studied with respect to much newly available material, the new theories of arthropod phylogeny and evolution, the interpretation of their taphonomy and palaeobioloy, and the reconstruction of the palaeoenvironment. The same applies to new material of the taxon Pygnogonida and other chelicerates as well as for remarkable new material of crustaceans of the taxon Phyllocarida. These outstanding new material linked with the aspects mentioned before take centre stage in the project proposed here. Additionally, the arthropods of the Hunsrück Slate show that stem group arthropods are not always “primitive” in a common sense. On the contrary, they indicate early and presumably multiple radiations, a high diversity, and a high degree of specialization of arthropods in the Palaeozoic. To illustrate these aspects and to compare the diversity and disparity of the Hunsrück arthropods with communities from the Cambrian as well as other time horizons is an important goal of the project proposed here.

下泥盆统洪斯吕克板岩（德国）以其独特的动植物区系和高质量的黄铁矿化石保存而闻名，尤其是节肢动物的高度多样性和其保存的显着性，其中一些具有未知的系统亲缘关系和模糊的系统发育。这些形态上非常古老的类群，如 Vachonisia rogeri、Mimetaster hexagonalis 和 Devonohexapodus。 bocksbergensis 的许多新材料、节肢动物系统发育和进化的新理论、埋藏学和古生物学的解释以及古环境的重建，这同样适用于 Pygnogonida 和其他螯虫类的新材料。以及甲壳类动物类群的杰出新材料这些与前面提到的方面相关的杰出新材料占据了拟议项目的中心位置。此外，洪斯吕克板岩的节肢动物表明，干群节肢动物并不总是一般意义上的“原始”，相反，它们表明节肢动物具有早期的、据称的多重辐射、高度的多样性和高度的专业化。为了说明这些方面并将洪斯吕克节肢动物与寒武纪以及其他时间范围的群落进行比较是一个重要的研究。这里提出的项目的重要目标。
