Cyathocrinites multbrachiatus Crinoid Calyx

Cyathocrinites multbrachiatus crinoid lived on the seafloor in the Mississippian Period. This fossil is on display on the first floor of the Indiana State Museum as of May 2012. More than likely this fossil is from Crawfordsville, Indiana. That is a some beautiful 3-D prep work!
