摘要

In this paper I describe late Maastrichtian echinoderm fauna from Chelm Quarry (eastern Poland) for the first time. The following crinoid taxa are identified: Bourgueticrinus sp., Bourgueticrinus sp. cf B. constrictus (v. HAGENOW), Isselicrinus buchii (RoEmER),Isocrinus? sp. and Roveacrinida indet. These crinoids are accompanied by echinoids referable to Echinocorvs sp. cf. E. scutata Leske and Cidarinae sp. et gen. indet. Crinoid material at hand is represented by disarticulated and abraded ossicles, which suggest that they were transported over long distances prior final burial. Semi-infaunal irregular echinoids, in turn, are preserved as more or less articulated tests, which were pyritized within the sediment immediately after death. This study confirms that Late Cretaceous crinoids from Poland are less abundant and diverse than in the neighbouring regions.

SP。 和Roveacriinida Indet。 这些十字曲面伴随着echInocorvs sp称为echinoids。 CF. E. Scutata Leske和Cidarinae SP。 ET Gen。 indet。 手指的红细胞材料由纯粹的和磨损的骨筒用,表明它们在最终埋藏的长距离中运输。 反过来,半婴儿不规则的echinoids被保存或更少的铰接试验,其在死亡后立即在沉淀物内蒸煮。 本研究证实,来自波兰的晚期白垩纪百屈曲比邻近地区更少于丰富和多样化。
