The name Lawsonian Stage is proposed as the highest stage of the Cambrian System (Stage 10). The base of the proposed Lawsonian Stage is at the First Appearance Datum (FAD) of the euconodont Eoconodontus notchpeakensis (Miller, 1969). That horizon, the base of the E. notchpeakensis Subzone of the Eo...
