Katian (Late Ordovician) conodonts on the northwestern margin of the North China Craton

Journal of Paleontology, 2021
AbstractUpper Ordovician strata exposed from the Baiyanhuashan section is the most representative Late Ordovician unit in the northwestern margin of the North China Craton (NCC). In total, 1,215 conodont specimens were obtained from 24 samples through the Wulanhudong and Baiyanhuashan formations at the Baiyanhuashan section.
