The Ediacaran Period: a new addition to the geologic time scale [PDF]
Lethaia, 2006 The International Union of Geological Sciences has approved a new addition to the geologic time scale: the Ediacaran Period. The Ediacaran is the first Proterozoic period to be recognized on the basis of chronostratigraphic criteria and the first ...

Paleontology: Paleogastronomy in the Ediacaran
Current Biology, 2022Preserved lipid biomarkers provide a unique window onto the biology of fossil organisms. A new study uses lipids to assess the gut contents of three fossils from the 'dawn of animals' in the Ediacaran, with implications for their feeding behaviors.

The redox structure of Ediacaran and early Cambrian oceans and its controls.
Science Bulletin, 2020The rapid diversification of early animals during the Ediacaran (635-541 Ma) and early Cambrian (ca. 541-509 Ma) has frequently been attributed to increasing oceanic oxygenation.

Ediacaran (635-542 million years ago) fossils have been regarded as early animal ancestors of the Cambrian evolutionary explosion of marine invertebrate phyla, as giant marine protists and as lichenized fungi. Recent documentation of palaeosols in the Ediacara Member of the Rawnsley Quartzite of South Australia confirms past interpretations of lagoonal-
