Zeacrinites wortheni Crinoid Calyx Fossil with Arms

These pictures appear to show a Zeacrinites wortheni (Hall, 1858) crinoid calyx fossil. What is nice about this fossil is that most of its arms are intact. One side has the remains of Fenestella bryozoan. It was found in the Glen Dean Member of Grayson County, Kentucky, USA. The fossil dates to the Mississippian Period. It is small about 3 cm tall.

Thanks to Kenny for the pictures.
