Look at the curves on this brachiopod. :) This unidentified brachiopod was found in the Jeffersonville Limestone which represents the Devonian Period rock. Found in Louisville, Kentucky USA.

Very nice spiriferid! I haven't run across any like that in my neck of the woods.

I now think this is a Devonian Period Brevispirifer brachiopod found locally in the Jeffersonville Limestone or in Ohio in the Columbus Limestone.
If you visit the Falls of the Ohio State Park (Clarksville, Indiana) it is a marker fossil for some of the limestone zones. When the water is down and visitors can hike across the spillway, there are exposed layers showing the fossilized remains of this brachiopod.
