‘Train crash crinoids’ represent an unusual mode of preservation of crinoid columns, superficially resembling to the carriages of a crashed train. They were exhumed from the White Peak (Mississippian limestones) of the Peak District in the Treak Cliff area of Castleton, Derbyshire, north‐central England, and were presented by Broadhurst & Simpson as part of a varied suite of observations supporting the recognition of an ancient apron reef (= fore‐reef slope). A re‐examination of these specimens shows that they were not live crinoids at or near the reef crest, but were recently dead specimens, recumbent on the sediment surface. Something triggered their movement into deeper water, and some travelled downslope parallel to the direction of movement and broke into a ‘train crash pattern’ when the lower end impacted on an immovable object.

再谈火车坠毁事故

“火车撞车事故缓和器”代表了一种非常规的保存撞车状柱的方式，表面上类似于撞车的车厢。它们是从英格兰中北部德比郡卡斯尔顿的Treak Cliff地区峰区的White Peak（密西西比石灰岩）中挖掘出来的，并由Broadhurst＆Simpson提出，作为一系列观测结果的一部分，这些结果支持对古代围裙礁（=前礁坡）。对这些标本进行的重新检查表明，它们不是礁顶或附近的活突状突，而是最近死亡的标本，靠在沉积物表面。某些东西触发了它们进入更深水域的运动，还有一些东西沿与运动方向平行的方向向下倾斜，并在下端撞击到不可移动的物体时闯入“火车碰撞模式”。
