Brachial valve
I'm glad I bought this specimen from reputable dealer who had a good ID on it. Trying to figure out Rhynconellid ID's can be very tough.

Anastrophia internascens brachiopod from the Waldron Formation
When I see a brachiopod name with "strophia" in it I tend to think of shells with a convex dorsal valve like Strophodonta or Strophomena. Anastrophia, however, is a Pentemerid type brachiopod from the Silurian aged Waldron Formation near Pegram, TN (Silurian, Wenlock epoch, Sheinwoodian to Homerian stage).
