This is a very rare multiple crinoid plate from LeGrand, Iowa. This legendary location has been closed to collecting for many decades. However, we have acquired a lot of crinoids from the collection of Professor Lowell Laudon, who found them in the late 1930's and kept them unprepared. They have just recently been prepared, using modern techniques under a microscope. There are four distinct crinoids on this piece - THREE Platycrinites symmetricus and a super Rhodocrinites kirbyi. One of the most interesting features of this locality is the different colors of calcite that have replaced the different crinoid species - this plate has the three Platycrinites preserved in white, while the Rhodocrinites is a dark brown! One of the Platycrinites has a full crown with pinnulated arms and a LONG corkscrew stem preserved. The Rhodocrinites is also extremely detailed. The fossil echinoderms have great color and contrast and are nicely showcased on the large, sculpted plate of limestone. This is one of the most detailed display plates we have seen from this classic locality.
