DOI: 10.1016/j.jsames.2019.05.015

Abstract: Abstract A well preserved assemblage of organic-walled microfossils is described from the Alicia and Cerro Negro formations of the La Providencia Group. The microbiota is dominated by Leiosphaeridia species (L. minutissima, L. tenuissima, L. crassa… read more here.

recommendations! Published in 2019 at "Palaeogeography, Palaeoclimatology, Palaeoecology"

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.

DOI: 10.1126/sciadv.ady3258

Abstract: Paleogeography of the Ediacaran Period has remained poorly understood because of paleomagnetic studies commonly yielding perplexing or conflicting data. Here, we report new magnetostratigraphic data from the Ediacaran Ouarzazate Group in the Anti-Atlas Mountains of… read more here.

DOI: 10.1134/s1028334x18110089

Abstract: The results of the first paleomagnetic study of a late Neoproterozoic magmatic complex on the Siberian paleocontinent (Siberia) using U–Pb geochronological data are presented. The igneous rocks of the Zimoveyniy massif (block) of the South… read more here.
