base notes	Proposed base of Middle Frasnian begins the first appearance of Palmatolepis punctata (base MN 5), the nearly concurrent appearance of Ancyrodella gigas serves as a related indicator that corresponds to the base of TR cycle IIc of Johnson et al. (1985) and the Middlesex deepening in eastern North America. Palmatolepis punctata is a widely distributed and widely recognized taxon.				comp notes
