Ulrichia ostracod from the Silica Shale

Another Ostracod from the Silica Shale sample from Sylvania, OH that I've found is Ulrichia.

A review of the book "Ostracods of the Middle Devonian Silica Formation" there are several different Ulrichia species. I think this most closely resembles Ulrichia spinifera based on plate 43 (pg. 270).  I collected this from eroded residue of the Silica Shale (Devonian, Givetian stage) near Sylvania, Ohio.
