Astronomically calibrating early Ediacaran evolution [PDF]
Nature CommunicationsThe current low-resolution chronostratigraphic framework for the early Ediacaran Period hampers a comprehensive understanding of potential trigger mechanisms for environmental upheavals and their connections to evolutionary innovation. Here, we establish

The terminal Ediacaran Tongshan Lagerstätte from South China [PDF]
Nature CommunicationsBecause the informative Burgess Shale-type preservation is uncommon in the Ediacaran, mouldic Ediacara-type preservation provides insight into the early evolution of organisms like metazoans (including typical fronds), protists, and algae.

Upwelling-driven high organic production in the late Ediacaran
Communications Earth & EnvironmentThe Ediacaran ocean (635-541 million years ago) is typically viewed as a stagnant, redox-stratified ocean with low phosphorus availability. However, this contradicts the high total organic carbon (up to 15 wt%) recorded in the upper Ediacaran Doushantuo ...

Sustained shift in the morphology of organic-walled microfossils over the Ediacaran–Cambrian transition [PDF]
Royal Society Open ScienceThe early (approx. 1650–540 Ma) history of eukaryotes was punctuated by several major—but enigmatic—environmental perturbations that potentially influenced the evolution of the Proterozoic biosphere, and the changing structure of Earth systems leading up

A putative triradial macrofossil from the Ediacaran Jiangchuan Biota [PDF]
iScienceSummary: The late Ediacaran Jiangchuan biota, from the Dengying Formation in eastern Yunnan, is well-known for its diverse macroalgal fossils, opening a window onto eukaryotic-dominated ecosystems from the late Neoproterozoic of South China.

‘Conga lines’ of Ediacaran fronds: insights into the reproductive biology of early metazoans [PDF]
Royal Society Open ScienceLate Ediacaran strata from Newfoundland, Canada (~574–560 Ma) document near-census palaeocommunities of some of the earliest metazoans. Such preservation enables reproductive strategies to be inferred from the spatial distribution of populations of ...

New insight into the global record of the Ediacaran tubular morphotype: a common solution to early multicellularity [PDF]
Royal Society Open ScienceThe tubular morphogroup is a common component of Earth’s first complex, multicellular communities—the Ediacaran biota—and offers valuable insight into biological traits that are fundamental to animal life because they have intriguing links to metazoan ...

Maintenance of the great late Ediacaran ice age [PDF]
Nature CommunicationsGeological records witness extensive glaciations in the late Ediacaran, ranging from ~580 to 560 Ma or younger. However, the explanation of maintenance for this regionally diachronous and globally continuous glacial epoch is still unclear.

Geophysical Monograph Series, Page 1-26., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.
