Zeacrinites wortheni Crinoid Calyx Fossil with Stem


This crinoid appears to be a Zeacrinites wortheni crinoid calyx fossil. As a bonus, this calyx has part of its stem. It was found in the Glen Dean Member of Grayson County, Kentucky, USA. The fossilized animal dates to Chesterian, Upper Mississippian Period.


Next to the calyx is some intricate Fenestella bryozoan fossils.


Thanks to Kenny for this remarkable fossil gift.
