Organic microfossils from the Ediacaran of Estonia—behind the scenes
, 2017 When seeing a play, one easily gets caught by everything therein; the music, the dancing, and of course, the story. Still, most of the work took place before it even had its premiere.

Ancient steroids establish the Ediacaran fossil Dickinsonia as one of the earliest animals
Science, 2018 Confirming the identity of early animals The first complex organisms emerged during the Ediacaran period, around 600 million years ago. The taxonomic affiliation of many of these organisms has been difficult to discern.

Towards an Ediacaran Time Scale : Problems, Protocols, and Prospects
, 2016 The Ediacaran Period follows the Cryogenian Period in the wake of a snowball Earth glaciation and precedes the Cambrian Period with its rising tide of animal radiation.

Three "First Places" for Ediacaran Period [PDF]
, 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 ...

Ecdysozoan-like sclerites among Ediacaran microfossils
, 2015 We report the occurrence of organically preserved microfossils from the subsurface Ediacaran strata overlying the East European Platform in Poland, in the form of sclerites and cuticle fragments of larger organisms.

, 2012 Two new developments in the taxonomy of temporality provide the focus for this discussion. One is the official recognition of a new, and very old, geologic period, the Ediacaran, now understood to occupy the stretch of deep time between 575 and 542 million years ago, directly preceding the Cambrian, with its remarkable radiation of life forms.

Lipid taphonomy in the Proterozoic and the effect of microbial mats on biomarker preservation [PDF]
The pre-Ediacaran biomarker record has several characteristic features that distinguish it from its Phanerozoic counterpart, including high concentrations of unresolved complex mixture (UCM), low concentrations or absence of eukaryotic steranes, and a ...
