Here is a nice multiple plate of crinoids from Crawfordsville Indiana that I had purchased unprepared and worked on before Thanksgiving. The standout crinoid on this pieces is a Parascytalocrinus which measures in at just over 2.5 inches long. Also included on this pieces is a Cyathocrinites Multibrachiatus and a small decadocrinus depressus. There are arms of a platycrinites next to the parascytalocrinus, but no calyx - having peeled off during extraction.
