Actinocrinites Crinoid Calyx Fossil

Over 10 years ago, a crinoid plate was found at Fort Payne Formation of Lake Cumberland Kentucky, USA. It is an interesting find in that the broken apart crinoid calyx can be seen on both sides of the plate. Also the plates have such a distinct and pronounced pattern. After showing this to my cousin Kenny, he determined the crinoid remains appear to be an unknown species of the genus Actinocrinites. The plate is about 17 cm long and 13 cm wide at maximum lengths. The individual plates are about 1.5 to 2 cm in diameter.
