The Virgilian series is the youngest part of the Pennsylvanianepoch in the North American geologic classification series.[1] During Virgilian times, the top of the Conemaugh and the entire Monongahela group were deposited.[2] As with other Carboniferous series, it comprises cyclothems, or distinct cycles of sedimentary rock formation.
