Penters Chert
The Penters Chert is a Devonian geologic formation in the Ozark Plateaus of Arkansas.[1] The name was introduced in 1921 by Hugh Dinsmore Miser in his study of Arkansas.[2] Miser designated a type locality near the old Penters Bluff railroad station in Izard County, Arkansas, however, he did not assign a stratotype. As of 2017, a reference section has not been designated for this unit.
