Here is a very prolific crinoid plate from Gilmore City, Iowa. The plate has TWELVE crinoids preserved (Eretmocrinus tentor, Dichocrinus multiplex, Aorocrinus iola, and Circidocrinus fimbria). The Gilmore City fauna is usually split into two zones - the zone with the large crinoids, and the zone with the smaller ones. This plate is very rare in that there is both a large AND small crinoids together on the plate! The large crinoid has an EXTREMELY LONG anal tube preserved - we do not know what could have caused this. All of the crinoids are well displayed, with LONG stems present on many of the crinoids. The fossil sea lillies have nice color and contrast and are naturally positioned on the LARGE plate of shale. This is one of the most interesting multiple plates we've seen from this historic crinoid locality.
