Pterocrinus acutus Crinoid with Snail Fossil


This crinoid calyx appears to be a Pterocrinus acutus (Wetherby, 1879). It has a snail fossil fossilized with it. The animals existed in the Mississippian Period and were found in the Glen Dean member of Grayson County Kentucky USA.

Thanks to Kenny for images.
