description

An exceptionally well-preserved and long crinoid stem is exposed on a slab of decorative Lower Carboniferous (Mississippian) limestone in front of an opticianʼs in Maastricht-Wyck, the Netherlands. The pluricolumnal is incomplete, but is c. 176.5 mm long by at least 7.0 mm wide and with a broad axial canal. The column is heteromorphic, N3231323. The specimen most likely represents a cladid or monobathrid that was preserved parallel to bedding.
