DEVONIAN BIOSTRATIGRAPHY OF DUSHAN, SOUTHERN GUIZHOU AND ITS CORAL EXTINCTION EVENTS

The shallow marine Devonian is well developed in Dushan, southern Guizhou and rich in fossil corals. The Devonian corals in Dushan flourished in a nearshore shallow water environment and all coral communities fall in the range of BA3 and BA4 (equivalent to the upper part of subtidal) in the Pedder and McLean's benthic assemblage scale.
