Recycling of the Proterozoic crystalline basement in the Coastal Block (Moroccan Meseta): New insights for understanding the geodynamic evolution of the northern peri-Gondwanan realm [PDF]
, 2018 Detrital zircon age spectra from the siliciclastic rocks of the Lalla Mouchaa Calcschists and El Jadida Dolomitic formations (the Coastal Block of the Moroccan Meseta) are dominated by Paleoproterozoic and Ediacaran ages.

The developmental biology of Charnia and the eumetazoan affinity of the Ediacaran rangeomorphs
Science Advances, 2021 Rangeomorphs represent a long-extinct group of eumetazoans with a bodyplan unlike anything alive today. Molecular timescales estimate that early animal lineages diverged tens of millions of years before their earliest unequivocal fossil evidence.

Dendrogramma, new Genus, with two new non- bilaterian species from the Marine Bathyal of Southeastern Australia (Animalia, Metazoa incertae sedis) – with similarities to some medusoids from the precambrian ediacara [PDF]
, 2014 This study examines a new species of dinosaur named Dendrogramma, which has been found near Bass Strait. Abstract A new genus, Dendrogramma, with two new species of multicellular, non-bilaterian, mesogleal animals with some bilateral aspects, D ...

Communications Earth & Environment, 2023 Increasing oxygenation of the early Ediacaran Ocean is thought to have been responsible for the emergence of early animals. Although geochemical studies have suggested periods of oceanic oxygenation in the Ediacaran, direct evidence for seafloor ...

Cryptic terrestrial fungus-like fossils of the early Ediacaran Period
Nature Communications, 2021 The colonization of land by fungi had a significant impact on the terrestrial ecosystem and biogeochemical cycles on Earth surface systems. Although fungi may have diverged ~1500–900 million years ago (Ma) or even as early as 2400 Ma, it is uncertain ...
