Grandma's Brachiopod

[Neanderthal Shaman]

My grandmother (rest her soul) was a high school science teacher way back in the day. She was also a SERIOUS rockhound. These days her extensive collection of odds and ends lives in the family attic. I was going through some of the boxes when I stumbled on this gorgeous pyrite encrusted brachiopod. Unfortunately many of the tags and labels for her pieces haven't survived into the present day, so I've been curious about what species this is and where it might be from. I've heard that Ohio has a deposit with lots of pyrite fossils and brachiopods. Anyone know of any other places where such a fossil might have come from, or is Ohio the most likely?

Sorry about the lighting, it's getting dark outside.

Beautiful brachiopod!

This is a spiriferid brachiopod from Ohio the species name is:

Paraspirifer bownockeri

Silica shale formation of Ohio

[ClearLake]

looks very much like a Paraspirifer bownockeri from the Silica Fm. of NW Ohio.  Even the adhering shale looks like it.
