I need help identifying this brachiopod from the Montour Fossil Pit. Devonian in age.

Maybe I'm wrong,but as far as I know,The Montour Fossil Pit in Danville, PA is in the Mahantango Formation (Middle Devonian), and from the brachiopods that could be find there I think Mucrospirifer mucronatus could be a possible match.

You are right, it is the Mahantango Formation. I forgot to mention that in my post. However, Mucrospirifer mucronatus has long "wings" on the sides, and this brachiopod has no evidence of there ever having been "wings" that broke off. I think GerryK's answer is probably closer.

Gerry has it.

 

Here are the figures of Mediospirifer audaculus from the Treatise (Part H) on Invertebrate Paleontology.

Mediospirifer sp. works for me also.

Agreed. Common find in the Mahantango and I've found similar from that pit and other nearby spots.
