Abstract
The wide-spread non-metamorphic shales of the Ruyang Group (1150-950 M a) in southern Shanxi, China contain abundant and well-preserved acrit archs and filamentous microfossils, suggesting a shallow-marine deposi tional environment. Acanthomorphic acritarchs obtained from both the B aicaoping Formation and the Beidajian Formation of the Ruyang Group in clude Shuiyousphaeridium Yan, emend. and a new genus Tappania Yin Lei- ming, gen. nov. In addition, Shuiyousphaeridium macroreticulatum (Du) Yan is emended and two new species Tappania plana Yin Lei-ming, sp. no v. and T. tubata Yin Lei-ming, sp, nov. are described.
