... in the Ediacaran (635–542 Ma). These microfossils, collectively known as the Doushantuo-Pertatataka–type acanthomorphs, have been variously interpreted as a polyphyletic assortment of resting stages of eukaryotes, including animals. The stratigraphic range of the acanthomorphs has long been thought...

... a prominent helical feature. The latter form, Spiralicellula bulbifera Xue, Tang, Yu, and Zhou, 1995 , was initially interpreted as a volvocacean green alga. After the re-assignment of most of the Doushantuo microfossils to embryos, a type of spherical fossil with a helical feature later named...

... for high resolution biostratigraphic correlation. Microfossil assemblages of the Pertatataka type—christened the Ediacaran Complex Acanthomorphic Palynoflora (ECAP) by Grey (2005) —all appear to occur within a limited interval of pre-Redkino Ediacaran time. Known from compressions in shale as well...

... of preservation of microfossils in the Doushantuo Formation at Weng’an in Guizhou Province ( Xiao et al. 2014 ). In both modes of microfossil preservation, there is no doubt that the internal body is an integral part of the vesicle, but no evidence of dividing cells is seen to suggest that it may be a metazoan...

... The principal problem in developing an acritarch-based biostratigraphy for the late Neoproterozoic is sampling. Almost nothing is known about the microfossil record within the ‘Cryogenian’ (see Corsetti et al. 2006 ), and only two Ediacaran sequences exhibit sufficient taxonomic richness...
