Plant fossils Cyclostigma kiltorkense and Lepidodendropsis hirmeri as well as trace fossils Zoophycos and Chondrites have been found and described at Hougaoping, Guangyuan City, western Yangtze Plate. The new data and sedimentary facies data indicate that the host strata were deposited during the Late Devonian. The depositional setting evolved from littoral and upper neritic environments to carbonate platform environments.
