The following are images of Lower Carboniferous Period (Mississippian) fossils. This first one is a elliptical crinoid columnal segment from maybe a Platycrinites.

This next image of a crinoid calyx that is probably an Eretmocrinus.

This next image is of an anal tube of an Eretmocrinus crinoid.
This might be a holdfast of an unidentified crinoid.
