...Xuejin Wu; Joseph P. Botting; Yuandong Zhang; Lucy A. Muir; Junye Y. Ma Abstract The Anji Biota is a unique deposit with exceptionally preserved sponges and other organisms in deep-water, uppermost Ordovician mudstone of Zhejiang Province, China. The sponge fossils preserve remarkable details...

...-dominated Anji Biota of the Upper Ordovician Wenchang Formation ( Metabolograptus persculptus Biozone) of Zhejiang Province, South China. One species, Avitograptus akidomorphus new species, is new; the other, Avitograptus acanthocystus new combination, which was previously placed in Climacograptus...

...Joseph P. Botting; Dorte Janussen; Yuandong Zhang; Lucy A. Muir Abstract The Anji Biota of Zhejiang Province, South China, is an exceptionally preserved, sponge-dominated fauna from the latest Ordovician interval, representing a deep-water environment and containing more than 100 sponge species...

...Han Wang; Simon J. Braddy; Joseph Botting; Yuandong Zhang Abstract An early form of eurypterids (Chelicerata), Archopterus anjiensis n. gen. n. sp., is described from the uppermost Ordovician Wenchang Formation of Anji County, Zhejiang Province, South China. It is the earliest record of eurypterids...

... is the latest Ordovician Anji Fauna in South China ( Botting et al., 2017 ), which is an exceptionally preserved fauna dominated by sponges. The known sponge diversity of the Huangshi Fauna is lower than that of the Anji Fauna (20 versus 100 species) ( Botting et al., 2020 ). However, the Huangshi Fauna...

... laminated dolostones depended on the quality and quantity of preserved organic matter (OM) and the geological conditions. The shales and algal laminated dolostones from the hanging wall imbricate zones of the Riasi thrust in north and south Anji, Talwara, Sangar, Dangakot and Bakkal sections exhibit very...

...Jianbo Liu; Yi Wang; Xiaole Zhang; Jiayu Rong Abstract The distribution pattern of early Telychian ( turriculatus–crispus graptolite biozone) red beds in the Eastern Yangtze Platform of South China is reconstructed based on regional geologic data. The red beds are developed in three areas, which...

...Daidu Fan; Congxian Li; Ping Wang Abstract Tonglu rhythmites (Upper Ordovician) in Zhejiang Province, east-central China, display three orders of cyclicity in sandstone and mudstone layer thickness. Millimeter-thick alternations of sandstone and mudstone laminae are ascribed to single tidal cycles...

.... This preservational bias severely limits a comprehensive understanding of the distribution and dynamic evolution of biodiversity in the Ordovician. Here, we report the Fuping Fauna, a deep-water slope facies Konservat-Lagerstätte from the Upper Ordovician (Katian) in the southern part of the North China craton...

... the tectonic evolution of the Lhasa Block. However, studies of the major benthic fossil group—the brachiopods—were only carried out by Zhan and Wu ( 1982 ) from the Xiala Formation and Zhan et al. ( 2007 ) from the middle and upper parts of the Yunzhug and Anjie formations at the Xiala section. Documentation...
