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.

Evolution of Holdfast Diversity and Attachment Strategies of Ediacaran Benthic Macroalgae
Frontiers in Earth Science, 2021 Holdfast morphologies and attachment strategies of benthic macroalgae are somewhat flexible and controlled by both the substrate condition and species.

Increase in metazoan ecosystem engineering prior to the Ediacaran–Cambrian boundary in the Nama Group, Namibia [PDF]
Royal Society Open Science, 2019 The disappearance of the soft-bodied Ediacara biota at the Ediacaran–Cambrian boundary potentially represents the earliest mass extinction of complex life, although the precise driver(s) of this extinction remain unresolved.

Ediacaran origin and Ediacaran-Cambrian diversification of Metazoa. [PDF]
Sci AdvThe timescale of animal diversification has been a focus of debate over how evolutionary history should be calibrated to geologic time. Molecular clock analyses have invariably estimated a Cryogenian or Tonian origin of animals while unequivocal animal fossils first occur in the Ediacaran.

Mineralogy, petrography, geochemistry of magnetite ore and sulfide minerals and the possible model of mineralization at Anomaly#3, Gol-e-Gohar, iron mine, Sirjan, Kerman [PDF]
پترولوژی, 2019 The Gol-e-Gohar anomaly#3 of Sirjan was initially formed by synchronous submarine basaltic volcanism and sedimentary rocks (basalt, shale, carbonates, sandstone, marl, chert-iron hydroxide-oxides) during Neoproterozoic (Ediacaran) and subsequently ...

Relating Ediacaran Fronds [PDF]
Paleobiology, 2016 Abstract Ediacaran fronds are key components of terminal-Proterozoic ecosystems. They represent one of the most widespread and common body forms ranging across all major Ediacaran fossil localities and time slices postdating the Gaskiers glaciation, but uncertainty over their phylogenetic affinities has led to uncertainty over issues ...
