DOI: 10.1016/j.palaeo.2019.05.036
Abstract: Abstract The Ediacaran to Cambrian periods are characterized by the diversification and extinction of metazoans, carbon-cycle perturbation, and ocean oxygenation. Ocean nutrient cycles play a major role in the primary production and productivity-driven shallow water… read more here.

DOI: 10.1093/nsr/nwad117
Abstract: The emergence of the Ediacara biota soon after the Gaskiers glaciation ca. 580 million years ago (Ma) implies a possible glacial fuse for the evolution of animals. However, the timing of Ediacaran glaciation remains controversial… read more here.
