Meristina maria brachiopod from the Waldron Shale

Since I mentioned the brachiopod genus Meristina in my last blog post I figured I should at least post an example of one. This is Meristina maria from the Waldron Shale of Shelby County, IN. It has a very deep sulcus and the pedicle valve is not as long as the brachial valve.

I purchased this fossil from a dealer along with a number of other fossils from the Waldron shale. The Waldron shale is Silurian aged and dated to the Wenlock epoch.
