Abstract
Zhong-Qiang Chen, G.R. Shi, Yongqun Gao, Jinnan Tong, Fengqing Yang & Yuanqiao Peng, June, 2009. A late Changhsingian (latest Permian) deep-water brachiopod fauna from Guizhou, South China. Alcheringa 33, 163–183. ISSN 0311-5518.
A deep-water brachiopod fauna (20 species in 19 genera) is described from the Late Permian Shaiwa Group of Ziyun, Guizhou, South China. New species include Pygmochonetes? shaiwaensis and Martinia ziyunensis. This fauna is associated with deep-water assemblages of pelagic radiolarians, foraminifers, bivalves and ammonoids. The brachiopod faunal correlations and age constraints of the associated fossil groups suggest that the Shaiwa fauna is late Changhsingian (latest Permian) in age. The Shaiwa fauna superficially resembles the coeval deep-water assemblage from Guangxi, South China; both are characterized by a mixture of deep-water brachiopods and shallow-water elements.

The senior author is also grateful to Dr Douglas Erwin of the National Museum of Natural History, Smithsonian Institution for allowing him, in 2006, to re-examine the type specimens of several genera described here. This study was supported by two Discovery Grants from the Australian Research Council (DP0452296, DP070938 to ZQC). The earlier field trips (in 1998–2000) were supported by two NSFC grants (Grants 40172012 and 40232025 to Prof. Feng-Qing Yang of China University of Geoscience, Wuhan). Critical comments by two journal reviewers and the journal editor Steve McLoughlin have greatly improved the quality of the paper, but all mistakes are ours.
