Diagnoza P1 elements elongate and sinusoidal, with narrow platform bearing a prominent anterior ridge, close to the blade along its whole length. Porównanie Transition from C. glabra to C. distorta took place early in the C. marginifera Zone. As already shown in the Canning Basin succession in Australia by Glenister and Klapper (1966), the change is gradual. Populations intermediate in age show more and more common elements having the narrow furrow between the ridge on the anterior lobe and the blade, including those usually classified as C. pectinata. Autekologia Występowanie geograficzne Łagów, Kowala, and Miedzianka; Ostrówka. Zasięg czasowy Typical populations are common in the C. marginifera Zone; rare specimens from higher horizons.
