$19.00

This is a super example of a crinoidal mortality hash plate. All the various parts are preserved in this mortality plate and there are too many crinoids to count. There is one "collapsed stem" that is prominent on the front of the plate and there appears to be a horn coral or something similar visible. This specimen comes from Ordovician period (approx. 440 to 485 million years ago) strata near Bardstown in Shelby county Kentucky, USA. This material has also been known to contain brachiopods, trilobites, bryzoans, corals, and gastropods.
