Brachiopod assemblages from the early Middle Triassic of Qingyan, Guizhou, Southwest China.

The article focuses on a study which examined brachiopod assemblages from Qingyan, Guizhou Province, China. Specimens of brachiopod were collected from the Qingyan Formation of Anisian. The total number of brachiopod species identified from 21 genera was 31, while seven assemblages were recognized. Results of the study showed that the Diholkorhynchia sinensis dominated the D assemblage. It also observed a stepwise diversification for the brachiopod faunas during the recovery/radiation time.
