Schizophoria iowaensis brachiopod from Iowa

Schizophoria appears to be a long lived genus with listing occurances from the Silurian through the Carboniferous. The specimen below is Schizophoria iowaensis from the Lime Creek formation of Iowa (Devonian, Fransian stage).

Brachial valve
Pedicle valve

It's overall shape reminds me of a Rhipidomella sp. except that Schizophoria has a much more convex brachial valve.
