| Abstract: | Eight categories of organic-walled coccoid microfossils in the c. 700-Ma-old Doushantuo Formation are described and named. Of these, one genus and species (Paratetraphycus giganteus) is new. Most of the microfossils are interpreted as being the remains of the Chroococcaceae and are morphologically comparable to those of the 650-Ma-old Yudoma microbiota and the 850-Ma-old Bitter Springs microbiota. These microfossils occur in non-stromatolitic cherts, adding preservational information to the study of Precambrian life. |
