Abstract

Occurrences of polyplacophorans new to Ohio include Camptochiton squarrosus Debrock, Hoare, and Mapes in the Desmoinesian Putnam Hill limestone andAcutichiton allynsmithi Hoare, Mapes, and Atwater in the shale associated with the Atokan Lower Mercer limestone. These occurrences extend the geographic ranges of these species to Ohio from Texas and Oklahoma respectively and extend the stratigraphic range of A. allynsmithi from the Morrowan to the Atokan. Arcochiton concisus n. sp. is described from the Atokan Boggs? limestone.
