Melocrinites sp. crinoid from Germany

This will be the last of the fossils that I received from my friend Nils to be featured for a while. I have a few more Devonian fossils from Germany to feature but I will post them up later. The featured fossil for today is a Melocrinites sp. calyx from the Oos formation (Devonian, Fransian) near Wallersheim, Germany. It's a little rough but you can make out the calyx plates and arm attachment points.

These next photos are of the calyx in profile and turned about 60 degrees counter clockwise between photos.

Thank you to Nils for this specimen!
