Theodossia hungerfordi brachiopod from Iowa

Another brachiopod from the Lime Creek Formation is Theodossia hungerfordi. From what info I can find (primarily Theodossia is a genus that is confined to the late Fransian stage of the Devonian. This is a fairly common species in the Lime Creek Fm. as is evidenced by the many specimens seen in auctions and at fossil shows.

The above specimen came from the Lime Creek Formation exposed in an old quarry that has been converted into a tourist park called the Fossil and Prairie Park Preserve near Rockford, Iowa.
