Brachiopod Paraspirifer bownockeri and Spinocyrtia

In addition to the New Albany Shale plants, brachiopods from Sylvania, Ohio (Lucas County) were brought in. These brachiopods have a really convex top shell that remind me of a shark fin. This one is called the Paraspirifer bownockeri found in the Silca Formation. It is from the Devonian period.
I think the red is pyritized part of the shell. Update: These last two pictures are of a brachiopod called Spinocyrtia.
