Whitfieldella from the Keyser formation

From the same exposure as the Meristina brachiopod I blogged about a few weeks ago comes this Whitfieldella sp. brachiopod. It's a fairly large fossil with a clear sulcus or "divot" down the middle of the pedicle valve. superficially it looks similar to a Meristina but it's longer and not as wide.

The Keyser formation is grouped across the boundary between the Silurian (Pridoli stage) and Devonian (Lochkovian stage) so it's hard to know exactly what ages the rocks are that I found the fossils in.

  1. those Silurian brachiopods are very hard to id. that's a nice one dave even though it looks like a different specimen between views.
