Examples of crowns representing the cladid crinoid family Pirasocrinidae, illustrating the extreme spinosity characteristic of this group. All crowns are from the similarly aged Barnsdall Formation of northeastern Oklahoma. A) Complete crown of the genus Plaxocrinus with the primibrachial spines marked by asterisks. These ossicles are the primary focus of this study, though many on this crown are broken close to their bases. Higher arrays of brachial spines are labeled as “bs”; a cross-sectional view of the ring of spines at the summit of the anal sac, most of which are also broken close to their bases, are labeled as “as.” B) View of the summit of the anal sac of the genus Polygonocrinus exemplifying the distinctive tegmen roofing plates and prominent ring of spines capping the anal sac. C) Same specimen shown in panel B, rotated 180° to show proximal (underside) view. Primibrachial spines are marked by asterisks; note also the ring of sharp spines in the background, below the summit of the anal sac. Scale bars = 10 mm; all photographs provided by R. Lewis.
