Mediospirifer Devonian Brachiopod

Here is a brachiopod fragment from North Vernon formation in Clark County, Indiana. It might be a Mediospirifer from the Devonian period. Normally, one would not post an image of fragment but only whole brachiopods. When turned over this one reveals part of its lophophore that has been broken off. This tube series makes it pretty neat since you get a view of the fossilized inside of the lophophore.

A little dot is visible inside the coil of the lophophore.
