Abstract
Well-preserved, three-dimensional microfossils are reported from a 3.7 m thick black phosphorite bed in the Sinian Doushantuo Formation at Wengan Phosphate Mine, Guizhou Province, southwest China. The diverse assemblage, observed in thin sections, comprises planktonic acritarchs, benthic cyanobacteria, bacteria, and thallophytes. Twenty one taxa are recognized, including 1 new genus and 4 new species. Acritarchs include Baltisphaeridium rigidum sp. nov., Vulcanisphaera phacelosa sp. nov., Comasphaeridium magnum Zhang 1984, Cymatiosphaeroides yinii sp. nov., Dicrospinasphaera zhangii gen. et sp. nov., Echinosphaeridium maximum (Yin, 1987) Knoll, 1992, Ericiasphaera sp., ?Ericiasphaera sp., Hocosphaeridium scaberfacium Zang & Walter, 1992, Meghystrichosphaeridium sp., Meghystrichosphaeridium wenganensis Chen & Liu, 1986, Polyhedrosphaeridium sp. The cyanobacteria and bacteria comprise Paratetraphycus giganteus Zhang, 1984, Gloeodiniopsis lamellosa (Schopf, 1968) Knoll & Golubic, 1979, Globophycus sp., Myxoc...
期刊介绍：
Alcheringa : An Australasian Journal of Palaeontology is the official journal of the Australasian Palaeontologists.
Alcheringa covers all aspects of palaeontology and its ramifications into the earth and biological sciences, including:
Taxonomy-
Biostratigraphy-
Micropalaeontology-
Vertebrate palaeontology-
Palaeobotany-
Palynology-
Palaeobiology-
Palaeoanatomy-
Palaeoecology-
Biostratinomy-
Biogeography-
Chronobiology-
Biogeochemistry-
Palichnology.
Review articles are welcome, and may be solicited from time to time. Thematic issues are also possible. Emphasis is placed on high quality and informative illustration, in both line drawings and photographs. Papers of general significance may receive preference over those of more local interest.
