Devonian Era Pyritized Paraspirifer Brachiopod Mollusk Shell Fossil 2"

Description

There are some imperfections as shown - please see photos for full details.  2" wide at the widest point.
This piece comes from the estate of a local Michigan fossil collector, who mined most of his collection himself.  Most were gathered in the Michigan and Illinois area, a few were gathered elsewhere.  I do not know where this particular piece was collected.
