..., as formerly designated. The thickness of the sequence ranges from 185 to 251 feet, and the rocks are widespread on the top and flanks of the White River Plateau. The entire sequence was formerly placed in the Dotsero dolomite. It is here divided into the Dotsero and Manitou formations. The Dotsero dolomite...

... the Clinetop Bed of the Dotsero Formation of Colorado. Stratigraphically, it ranges from the Idahoia to the Saukia trilobite zones of the Upper Cambrian Ptychaspid Biomere. Ecologically, Wilbernicyathus Wilson, 1950 occupies a reefal niche and constitutes up to 30% of the reef volume. These Late Cambrian...
