Biogeochemical changes across the Ediacaran-Cambrian transition in South China
TLDR
In this paper, it is shown that sub-surface bioturbation helped to strengthen the relationship between benthic oxidation state and P-retention, thus tightening an important negative feedback that helps to stabilize productivity, climate and oxygen levels in the modern Earth system.About:

Cambrian Small Bilaterian Fossils from 40 to 55 Million Years Before the Cambrian
Jun-Yuan Chen,David J. Bottjer,Paola Oliveri,Stephen Q. Dornbos,Feng Gao,Seth Ruffins,Huimei Chi,Chia-Wei Li,Eric H. Davidson +8 more
TL;DR: The first evidence confirming the phylogenetic inference that Bilateria arose well before the Cambrian was found in the Doushantuo Formation, China, dating from 40 to 55 million years ago as discussed by the authors.

Global climate, sea level cycles, and biotic events in the Cambrian Period
Loren E. Babcock,Loren E. Babcock,Shanchi Peng,Carlton E. Brett,Maoyan Zhu,Per Ahlberg,Michael Bevis,Richard A. Robison +7 more
TL;DR: In this article, high-resolution chronostratigraphy of the Cambrian provides an updated age model for various geologic and biotic events that occurred during this critical period of Earth history.

Nitrogen and organic carbon isotope stratigraphy of the Yangtze Platform during the Ediacaran-Cambrian transition in South China
Lorenzo Cremonese,Graham A. Shields-Zhou,Graham A. Shields-Zhou,Ulrich Struck,Hong-Fei Ling,Lawrence M. Och +5 more
TL;DR: In this paper, the authors investigated biogeochemical cycling, stratigraphic correlation and isotope systematics over the crucial Ediacaran-Cambrian transition in the South China Basin.

Late Neoproterozoic seawater oxygenation by siliceous sponges.
Michael Tatzel,Friedhelm von Blanckenburg,Marcus Oelze,Julien Bouchez,Dorothee Hippler,Dorothee Hippler +5 more
TL;DR: It is shown that siliceous sponges increased seawater dissolved oxygen concentrations by redistributing organic carbon oxidation through filtering suspended organic matter from seawater, potentially triggering the diversification of eumetazoans.

Evolution of oceanic molybdenum and uranium reservoir size around the Ediacaran–Cambrian transition: Evidence from western Zhejiang, South China
TL;DR: In this paper, the authors conducted a series of geochemical analyses on the upper Lantian, Piyuancun, and Hetang formations in the Chunye-1 well, part of the lower Yangtze Block in western Zhejiang.

Proterozoic ocean chemistry and evolution: A bioinorganic bridge?
Ariel D. Anbar,Andrew H. Knoll +1 more
TL;DR: Recent data imply that for much of the Proterozoic Eon, Earth's oceans were moderately oxic at the surface and sulfidic at depth, and biologically important trace metals would have been scarce in most marine environments.

Bioturbation and remineralization of sedimentary organic matter: effects of redox oscillation☆
TL;DR: A variety of field and laboratory observations demonstrate that particle reworking and irrigation activities of benthic fauna promote the remineralization of organic matter in bioturbated Corg-rich sediments.
Journal ArticleDOI
Three-dimensional preservation of algae and animal embryos in a Neoproterozoic phosphorite
TL;DR: Embryos preserved in early cleavage stages indicate that the divergence of lineages leading to bilaterians may have occurred well before their macroscopic traces or body fossils appear in the geological record.

Pulsed oxidation and biological evolution in the Ediacaran Doushantuo Formation
Kathleen A. McFadden,Jing Huang,Xuelei Chu,Ganqing Jiang,Alan J. Kaufman,Chuanming Zhou,Xunlai Yuan,Shuhai Xiao +7 more
TL;DR: High-resolution geochemical data from the fossil-rich Doushantuo Formation in South China are reported that confirm trends from other broadly equivalent sections and highlight key features that have not been observed in most sections or have received little attention.

The late Precambrian greening of the Earth
L. Paul Knauth,Martin J. Kennedy +1 more
TL;DR: All published oxygen and carbon isotope data for Neoproterozoic marine carbonates are considered in terms of processes known to alter the isotopic composition during transformation of the initial precipitate into limestone/dolostone, and it is shown that the combined oxygen andcarbon isotope systematics are identical to well-understood Phanerozoic examples.
