Abstract: | ‘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. |
