LATE CARBONIFEROUS FUSULINIDS FROM THE TYPE SECTION OF DALAAN STAGE IN CHINA

The present paper studies in detail the fusulinids from the stratotype section of the Dalaan Stage. The fusulinids of 74 species and subspecies belonging to 14 genera, including 1 unnamed species (as shown in table 1) are described and illustrated. Six major fusulinid zones have been established in ascending order as follows: 1) Profusulinella priscoidea-P. parva Zone, 2) Profusulinella aljutovica-Taitzehoella taitzehoensis extensa Zone, 3) Fusulinella obesa-F. eopulchra Zone, 4) Fusulina lanceolata-Fusulinella vozhgalensis Zone, 5) Fusulina pakhrensis-Pseudostaffella paradoxa Zone and 6) Fusulina cylindrica-F. quasifusulinoides Zone. At the stratotype section, the Dalaan stage is corresponding to the upper part of Bashkirian and the most part of Moscovian of the international stratigraphic chart (as shown in table 2) or the combination of Atokan and Desmoinesian of North America.
