Three "First Places" for Ediacaran Period

, 2004
Definition of a new geologic period for the last interval of the Proterozoic Eon, the Ediacaran, was recently ratified by the IUGS. The Ediacaran Period is the first Proterozoic period to be recognized on the basis of chronostratigraphic criteria, the ...

Periodic ocean oxygenation events during the mid-Ediacaran

The Ediacaran Gaskiers Glaciation (579.78–579.44 million years ago) is the last major climatic event of the Neoproterozoic, but the contemporaneous ocean redox conditions remain unclear.

Upwelling-driven high organic production in the late Ediacaran

Communications Earth & Environment
The Ediacaran ocean (635-541 million years ago) is typically viewed as a stagnant, redox-stratified ocean with low phosphorus availability. However, this contradicts the high total organic carbon (up to 15 wt%) recorded in the upper Ediacaran Doushantuo ...

Composition and pore characteristics of black shales from the Ediacaran Lantian Formation in the Yangtze Block, South China

, 2016
The Ediacaran period was critical in the evolution of the biosphere and ocean in the history of the Earth. Shales rich in organic matter (OM) are well developed for this period in the Yangtze Block, China, and have recently been related to shale gas ...

Quantitative Approaches to Understanding Ediacaran Ecology [PDF]

, 2013
Ediacaran macrofossils occupy a crucial position in the history of life on Earth, marking the transition between the microbially dominated Proterozoic and the Cambrian explosion of modern animals.

Viewing the Ediacaran biota as a failed experiment is unhelpful [PDF]

Macroscopic organisms from the late Ediacaran period have often been described as failed experiments in the history of life. We argue that the field of Ediacaran palaeobiology should dispense with unhelpful historical classification schemes and embrace ...

Volcano-hydrothermal phosphorus pulses fostered ocean oxidation during Ediacaran phosphogenesis in South China

Communications Earth & Environment
Phosphorus availability limits marine productivity and influences ocean oxygenation, yet the mechanisms driving phosphorus enrichment in Ediacaran oceans remain uncertain.
