Zeacrinites wortheni Crinoid Calyx Fossil

These pictures appear to show a Zeacrinites wortheni crinoid calyx fossil. If you look close at the top of the calyx image is a small point that appears to be part of the anal tube. It was found in the Glen Dean Member of Grayson County, Kentucky, USA. The fossil dates to the Mississippian Period. It is small about 1.5 cm tall.

Thanks to Kenny for the pictures.
