MICROBIOTA FROM THE NEOPROTEROZOIC LIULAOBEI FORMATION IN THE HUAINAN REGION, NORTHERN ANHUI, CHINA
Abundant and well-preserved acritarchs have been obtained from shales of the Neoproterozoic Liulaobei Formation in the Huainan region, northern Anhui Province, China. This microfossil assemblage, consisting of 9 genera, 11 species and an undetermined form, is dominated by sphaeromorphic acritarchs,...
