Amazing LeGrand Sea Floor Slab with Many Crinoids

Name: LeGrand Crinoid Slab
Age:  Mississippian
Formation:  Hampton Formation
Location:  LeGrand, Iowa
Size: Plate is 12.5 inches diagonal
Price: SOLD

Specimen SSS956

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 about two dozen crinoids on this piece including Platycrinites symmetricus, Rhodocrinus kirbyi, Cusacrinus nodobrachiatus, Megistocrinus nobilis, Dichocrinus cinctus, and MANY other types. 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 all three colors represented - white, tan and dark brown!) The fossil echinoderms have great color and contrast and are naturally clustered on the large, natural plate of limestone. This is one of the most prolific display plates we have seen from this classic locality.
