Its lowest occurrence in the North American faunal province is in the uppermost Cambrian Corbinia apopsis Subzone of the Saukia Zone. These data, combined with the appearance of the olenid trilobites Jujuyaspis and Parabolinella in the Acado-Baltic lower Tremadocian and in the North American lowermost Ordovician Missisquoia and Symphysurina Zones, suggest but do not prove an approximate equivalency of the Cambrian-Ordovician boundary in the two faunal provinces.
