Here is a very nice echinoderm plate from the Lower Burlington Formation of Missouri. In the bottom left of the slab is a large example of Cusacrinus ectypus. This rare crinoid has a large cup that is composed of many stellate plates. The tegmen has a multitude of small plates that are very protuberant - almost spiked! It is highly unusual to find this crinoid with the tegmen intact. There are also two other fossils, Agaricocrinus brevis (center) and Cryptoblastus melo, on the plate. The melon-shaped blastoid has thin ambulacra and granulose plates. All of the echinoderms are wonderfully 3-dimensional and exhibit excellent detail. The white color of the fossils contrasts nicely with the orangish-brown matrix. The echinoderms are well positioned on the rectangular block of limestone that contains many tiny crinoid fragments. This is a great specimen of this uncommon crinoid and other echinoderms.
This fossil was collected and obtained legally, and is also being sold legally.
