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).

An Ediacaran trace-like body fossil of a Palaeopascichnus specimen from Oman under 3D micro-tomography

Palaeopascichnus is an Ediacaran organism, whose phylogenetic affiliation and functional anatomy are both shrouded in mystery. Different studies and assessments have interpreted this fossil as macrophytes or foraminifera-like protists.

Reviewing the Ediacaran fossils of the Long Mynd, Shropshire

The Precambrian fossils of the Long Mynd, Shropshire, are becoming increasingly important to studies of palaeoecology and evolution immediately prior to the 'Cambrian Explosion' of animal life.

Ediacaran 2,500-km-long synchronous deep continental subduction in the West Gondwana Orogen

, 2014
International audienceThe deeply eroded West Gondwana Orogen is a major continental collision zone that exposes numerous occurrences of deeply subducted rocks, such as eclogites.

Ecological interactions in Cloudina from the Ediacaran of Brazil: implications for the rise of animal biomineralization

Scientific Reports, 2017
At the Ediacaran/Cambrian boundary, ecosystems witnessed an unparalleled biological innovation: the appearance of shelled animals. Here, we report new paleoecological and paleobiological data on Cloudina, which was one of the most abundant shelled ...

Age constraints for the Ediacaran-Cambrian boundary in the Iberian Chains, NE Spain

, 2019
The Paracuellos Group is the oldest sedimentary sequence of the Iberian Chains in north-east Spain. The group is subdivided into three formation which are, in stratigraphic order, the Sestrica Formation, known only from drill cores, the Saviñan Formation
