Millimetric-centimetric carbonaceous compressions are exceptionally preserved on bedding planes in dark grey argillaceous shales of the Neoproterozoic, North China. Four morphological taxa are recognized. Most specimens are assigned to Chuaria-Tawuia types. Some specimens show both a holdfast and a vegetative thallus, indicating they were benthic multicellular algae.Each form is characterized by a certain morphological appearance, e. g. spheroidal-Chuaria circularis, tomaculate-Tawuia delensis, taenioidal-Tyrasotaenia podolica, annulated, and tomaculate, which had been described as metazoan, Sinosabellidites huainanensis. Two to three different forms and more than 10 individuals are well preserved on the same bed within an area less than 100 cm 2. The assemblage consisting mostly of macroscopic remains, Chuaria and Tawuia, are common in Neoproterozoic paleobiotas. Similar ones have been reported from the Little Dal Group of the Mackenzie Mountain and Shaler Supergroup of the Victoria Island, Canada.
