An ecologically mixed brachiopod fauna from Changhsingian deep‐water basin of South China: consequence of end‐Permian global warming

The Late Permian Shaiwa Group of the Ziyun area of Guizhou, South China is a deep-water facies succession characterized by deep-water assemblages of pelagic radiolarians, foraminifers, bivalves, ammonoids and brachiopods. Here we report 20 brachiopod species in 18 genera from the uppermost Shaiwa Group. This brachiopod fauna is latest Changhsingian in age and dominated by productides. The palaeoecologic and taphonomic analysis reveals that the brachiopod fauna is preserved in situ. The attachment modes and substratum preference demonstrate that the Shaiwa brachiopod fauna comprises admixed elements of deep-water and shallow-water assemblages. The presence of the shallow-water brachiopods in the Shaiwa faunas indicates the involuntary settlement of shallow-water brachiopods. The stressed ecologic pressure, triggered by warming surface waters, restricted ecospace and short food sources, may have forced some shallow-water elements to move to hospitable deep-water settings and others to modify their habiting behaviours and exploit new ecospace in deep-water environments. We infer that the end-Permian global warming and subsequent transgression event may have accounted for the stressed environmental pressure in the shallow-water communities prior to the end-Permian mass extinction.

New Early Triassic Lingulidae (Brachiopoda) genera and species from South China

Peng, Y. & Shi, G.R., June, 2008. New Early Triassic Lingulidae (Brachiopoda) genera and species from South China. Alcheringa 32, 149–170. ISSN 0311-5518. Two new genera, Sinolingularia gen. nov. and Sinoglottidia gen. nov., together with three new species, Sinolingularia huananensis gen. et sp. nov., Sinolingularia yini gen. et sp. nov. and Sinoglottidia archboldi gen. et sp. nov., are described on the basis of a large collection of well-preserved specimens from several sections straddling the Permian – Triassic boundary in South China.

Discovery of late Changhsingian (latest Permian) brachiopod Attenuatella species from South China

Weihong He, G.R. Shi, Qinglai Feng, Yuanqiao Peng, September, 2007. Discovery of late Changhsingian (latest Permian) brachiopod Attenuatella species from South China. Alcheringa 31, 271-284. ISSN 0311-5518. Attenuatella mengi sp. nov. and ?Attenuatella sp. from the Talung Formation, southern Guangxi Zhuang Autonomous Region, South China, are described herein. This discovery represents the first report of Attenuatella from the late Changhsingian (latest Permian) in South China and provides evidence that Attenuatella expanded its range from high-latitude cold-water regions to palaeoequatorial warm water areas in the Late Permian. Attenuatella species appear to have been pseudoplanktonic, judging from their hair-like spinose ornamentation, which could have contributed to the global palaeogeographical distribution of Attenuatella.

A new bivalve fauna from the Permian–Triassic boundary section of southwestern China

Gao, Y., Shi, G.R. & Peng, Y., March, 2009. A new bivalve fauna from the Permian–Triassic boundary section of southwestern China. Alcheringa 33, 33–47. ISSN 0311-5518. A new marine bivalve fauna from the continuous Upper Permian Longtan Formation to Lower Triassic Yelang Formation of the Zhongzai section in southwestern China is documented. Four bivalve assemblages spanning the Permian–Triassic boundary are recognized and regionally correlated in South China. The bivalve assemblages changed from elements dominated by Palaeozoic types to those dominated by Mesozoic types. Three new species, Claraia zhongzaiensis sp. nov., Claraia sp. nov. 1 and Claraia sp. nov. 2, are described.

A late Changhsingian (latest Permian) deep-water brachiopod fauna from Guizhou, South China

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.
