Species diagnosis tables for: Crinoids from the Wooster Shale Member of the Cuyahoga Formation, Carboniferous (Mississippian, Tournaisian) of Northeastern Ohio

Nine crinoids are described from the Wooster Shale Member of the Cuyahoga Formation from Wayne and Ashland counties, Ohio, USA. Identifiable elements of the fauna include five camerate crinoids, one flexible crinoid, and three other eucladid crinoids. Five new species are described, including Cactocrinus woosterensis n. sp., Cusacrinus brushi n. sp., Agaricocrinus murphyi n. sp., Decadocrinus laevis n. sp., and Decadocrinus inordinatus n. sp. Overall, the distribution of crinoid clades in the Wooster Shale is similar to that of the stratigraphically lower Meadville Shale Member of the Cuyahoga Formation, although less diverse and with only one species (Cyathocrinites simplex) in common. Many of the Wooster Shale crinoids are completely or partially preserved with siderite in either nodules or within siderite beds. These crinoids are commonly preserved in trauma postures, which is characteristic of burial in episodic high turbulence events. The paleoenvironments and taxa of the two Cuyah..., These data were compiled from the 19th, 20th, and 21st century literature on fossil crinoids.,本次研究记述了产自美国俄亥俄州韦恩县与阿什兰县凯霍加组（Cuyahoga Formation）伍斯特页岩段（Wooster Shale Member）的9个海百合（crinoids）分类单元。该动物群可识别的化石组分包含5种闭系海百合（camerate crinoids）、1种柔系海百合（flexible crinoid）以及3种其他真枝海百合类（eucladid crinoids）。本次共记述5个新种，分别为伍斯特仙人掌海百合（Cactocrinus woosterensis n. sp.）、布拉什库萨海百合（Cusacrinus brushi n. sp.）、墨菲伞形海百合（Agaricocrinus murphyi n. sp.）、光滑十腕海百合（Decadocrinus laevis n. sp.）与无序十腕海百合（Decadocrinus inordinatus n. sp.）。整体而言，伍斯特页岩段中海百合演化支的分布格局与凯霍加组层位更低的梅德维尔页岩段（Meadville Shale Member）相似，尽管其多样性更低，且二者仅共享1个物种——简单杯海百合（Cyathocrinites simplex）。多数产自伍斯特页岩段的海百合标本均以完整或部分保藏的形式，赋存于菱铁矿结核或菱铁矿岩层中。这些海百合通常以创伤姿态保存，这是其经历幕式强湍流事件埋藏的典型特征。两处凯霍加组（原文此处未完整表述）的古环境与分类群信息，本次研究数据均整理自19、20及21世纪有关化石海百合的相关文献。
