Dasciocrinus spinosus crinoid from Alabama

Here is a pretty decent calyx of a Dasciocrinus spinosus crinoid from the Bangor Limestone of Alabama. It looks like the whole calyx is present with a good portion of the arms intact as well. There are even some pinnules showing on the left most arm.

I purchased this specimen from a seller on E-bay names Larrysfossils. The Bangor Limestone is Mississippian in age and can be found across the south east United States.
