Causes and consequences of end-Ediacaran extinction: An update [PDF]
Cambridge Prisms: Extinction, 2023 Since the 1980s, the existence of one or more extinction events in the late Ediacaran has been the subject of debate. Discussion surrounding these events has intensified in the last decade, in concert with efforts to understand drivers of global change ...

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 ...
