Today I have a brachiopod specimen called Merista tennesseensis from the Silurian (Wenlock epoch) aged Bob Limestone member of the Brownsport Formation. It was found near Bath Springs, TN. I was confused when I saw the name at first because of the similarity to Meristella (let alone Meristina!) but it is a completely different genus.
I found a couple of records on Yale's online collection of fossils in their Peabody Museum for Merista tennesseensis. This one was the only one that had a decent specimen picture.
