TLDR
This taxonomic re-evaluation follows comparison with other Ediacaran species and taxonomic concepts to accommodate the morphologic variety of acritarchs from China and Australia published recently and is intended to simplify the identification and to eliminate some superfluous taxa.About:

The Ediacaran Period
TL;DR: In this article, an essential reference for all geoscientists, including researchers, students, and petroleum and mining professionals, is presented, illustrated with numerous colour charts, maps and photographs.

The diversification and extinction of Doushantuo‐Pertatataka acritarchs in South China: causes and biostratigraphic significance
TL;DR: In this paper, the authors present preliminary biostratigraphic data from the Doushantuo Formation in the East Yangtze Gorges area and new delta(13)C chemostratigram data for the Weng'an Formation.
Journal ArticleDOI
The Proterozoic Record of Eukaryotes
TL;DR: For example, the authors show that mean within assemblage diversity increases through the Proterozoic Eon due to an increase in high diversity assemblages, and that this trend is robust to various external factors including lithology and paleogeographic location.
Journal ArticleDOI
Phosphatized Acanthomorphic Acritarchs and Related Microfossils from the Ediacaran Doushantuo Formation at Weng'an (South China) and their Implications for Biostratigraphic Correlation
TL;DR: In this paper, a systematic treatment of acanthomorphs (and related spheroidal microfossils) from the Doushantuo Formation at Weng'an is presented.
Journal ArticleDOI
Remarkable insights into the paleoecology of the Avalonian Ediacaran macrobiota
TL;DR: It is suggested that Avalonian ecosystems witnessed the appearance of novel nutrient sources, offering new opportunities and niches for benthic organisms, and cast doubt on previous suggestions that the Avalonian assemblages were largely composed of metazoans.

A discussion and proposals concerning fossil dinoflagellates, hystrichospheres, and acritarchs, ii.
TL;DR: In 19611, it was suggested that many post-Paleozoic organic microfossils that had been called hystrichospheres are really dinoflagellate cysts, and several nomenclatural changes and taxonomic revisions affecting these fossils are proposed.

Age of Neoproterozoic Bilatarian Body and Trace Fossils, White Sea, Russia: Implications for Metazoan Evolution
Mark W. Martin,Dmitriy V. Grazhdankin,Samuel A. Bowring,David Evans,M. A. Fedonkin,Joseph L. Kirschvink +5 more
TL;DR: A uranium-lead zircon age for a volcanic ash interstratified with fossil-bearing, shallow marine siliciclastic rocks in the Zimnie Gory section of the White Sea region indicates that a diverse assemblage of body and trace fossils occurred before 555.3 +/- 0.3 million years ago, making co-occurring trace fossils the oldest that are reliably dated.
Journal ArticleDOI
The Ediacaran Period: A New Addition to the Geologic Time Scale
TL;DR: The International Union of Geological Sciences has approved a new addition to the geologic time scale: the Ediacaran Period as mentioned in this paper, which is the first Proterozoic period to be recognized on the basis of chronostratigraphic criteria and the first internationally ratified, chronostrategically defined period of any age to be introduced in more than a century.

Life after snowball: The oldest complex Ediacaran fossils
Guy M. Narbonne,James G. Gehling +1 more
TL;DR: Newly discovered fronds of the Ediacaran index fossil Charnia from the Drook Formation of southeastern Newfoundland are the oldest large, architecturally complex fossils known anywhere as mentioned in this paper.

A New Period for the Geologic Time Scale
TL;DR: The geologic time scale is in need of an update, given that the last modification took place in 1891, and the Ediacaran Period is added by the International Union of Geological Sciences.
