摘要
Seven species of rugose corals are described from Permian (mostly Leonard series) strata in the Basin and Range province of Nevada and California. Caninia trojana, Lithostrotionella mokomokensis, Lithostrotionella dilatata, Diphyphyllum connorsensis, Thysanophyllum princeps, Lonsdaleia illipahensis, and Lonsdaleia cordillerensis are named. The corals occur in thick successions of commonly cyclical alternations of limestone and sandstone near the eastern margin of the Cordilleran geosyncline. Local distribution and biostromal development can be used in subdividing and mapping the Permian strata of E.-central Nevada.
