This brachiopod fossil appears to be the
Brevispirifer gregarius (Clapp, 1857). It was found in the Jeffersonville Limestone which dates to the Middle Devonian Period. The fossil was probably found around Louisville, Jefferson County, Kentucky. It was from the collection of
Dr. James Conkin (1924-2017) with no label. The species name attributed to
Dr. Asahel Clapp (1792-1862).
