Some fossils, such as crinoid stems, are not widely appreciated by collectors and researchers, yet can provide unique data regarding taphonomy and palaeoecology. A long crinoid pluricolumnal showing a distinctive pattern of preservation was collected from the Clare Shale Formation (Upper Carboniferous) at Fisherstreet Bay, Doolin, County Clare, western Ireland. The specimen is partly disarticulated and represents the mesistele to mesistele/dististele transition; attachment was by unbranched long, slender radices; pluricolumnal heteromorphic; fragments of pluricolumnal are of multiples of a unit length. This specimen, cladid? sp. indet., slumped to the seafloor after death and started to disarticulate as ligaments rotted. By reference to the broken stick model, the pattern of disarticulation suggests that the noditaxis of the heteromorphic stem was N212.

一些化石，例如海百合茎，并未受到收藏家和研究人员的广泛赞赏，但可以提供有关分类学和古生态学的独特数据。从爱尔兰西部克莱尔郡杜林的Fisherstreet湾的克莱尔页岩地层（上部石炭纪）中收集了一个长的滨海蛇形胸骨，显示出独特的保存方式。标本部分脱离，代表了中胚层到中胚层/远端的过渡；附着是通过无分支的长而细长的半径形成的；多柱状异形; 胸膜的碎片是单位长度的倍数。这个标本，拍手？sp。死亡后跌落到海底，并随着韧带腐烂而开始脱节。参照断棍模型，
