A Stratified Redox Model for the Ediacaran Ocean [PDF]

, 2010
The Ediacaran Period (635 to 542 million years ago) was a time of fundamental environmental and evolutionary change, culminating in the first appearance of macroscopic animals.

Indentor-escape, delamination and orogenic collapse of the ca. 600-500 Ma East African/Antarctic Orogen in Mozambique and Dronning Maud Land (East Antarctica) [PDF]

, 2010
The East African/Antarctic Orogen (EAAO) is one of the largest orogenic belts on the planet, resulting from the collision of various parts of East and West- Protogondwana between ca. 600 and 550 Ma.

Comment on ‘‘Geodynamic evolution of the SW Europe [PDF]

, 2009
Ribeiro et al. [2007] have presented a geodynamic view of the SW Iberia Variscides based on data from Portugal. Their treatment of already published data is commendable, and the knowledge gained will surely encourage the discussion of the SWEurope ...

The Geology as an indispensable tool for optimizing the exploration of dimension Stones [PDF]

, 2012
Like any Geological Resource, the Dimension Stones can only be exploited where they occur. How they occur is a reflection of geological history that presided over its formation.

Palaeoceanographic controls on spatial redox distribution over the Yangtze Platform during the Ediacaran–Cambrian transition [PDF]

, 2016
The Ediacaran–Cambrian interval was an eventful transitional period, when dynamic interactions between the biosphere and its physical environment allowed the Earth System to cross into a new state, characterized by the presence of metazoans, more equable

The Location and Styles of Ice-Free “Oases” during Neoproterozoic Glaciations with Evolutionary Implications [PDF]

, 2012
Evidence based on molecular clocks, together with molecular evidence/biomarkers and putative body fossils, points to major evolutionary events prior to and during the intense Cryogenian and Ediacaran glaciations. The glaciations themselves were of global

Isotopes, Ice Ages, and Terminal Proterozoic Earth History [PDF]

, 2014
Detailed correlations of ancient glacial deposits, based on temporal records of carbon acid strontium isotopes in seawater, indicate four (and perhaps five) discrete ice ages in the terminal Proterozoic Eon.

Chronology of Ediacaran sedimentary and biogeochemical shifts along eastern Gondwanan margins

Communications Earth & Environment
Determining causal relationships between environmental change and early animal evolution has been limited by our lack of a robust temporal framework for the Ediacaran Period (635-539 million years ago).

Of time and taphonomy: preservation in the Ediacaran [PDF]

, 2014
The late Neoproterozoic witnessed a revolution in the history of life: the transition from a microbial world to the one we know today. The enigmatic organisms of the Ediacaran hold the key to understanding the early evolution of metazoans and their ...
