Fusulinid
The discovery of fusulinid-bearing oolites from the Tengchong Block in western Yunnan, China represents hitherto the sole occurrence of Early Permian oolitic carbonates in the eastern Cimmerian region.

Together, these rocks compose the Deadman Bay Volcanics. Fusulinid fossils in the limestone indicate that the rocks formed in the Late Permian or Early Triassic period.
