TL;DR: A composite section in Namibia providing biostratigraphic and chemostratigram data bracketed by radiometric dating constrains the Ediacaran-Cambrian boundary to 538.6-538.8 Ma, more than 2 Ma younger than previously assumed as mentioned in this paper.
Stratigraphy, palaeontology and geochemistry of the late Neoproterozoic Aar Member, southwest Namibia: Reflecting environmental controls on Ediacara fossil preservation during the terminal Proterozoic in African Gondwana

TL;DR: The Aar Member of the Dabis Formation (Kuibis Subgroup, Nama Group) near Aus in southwest Namibia is well preserved in a Late Neoproterozoic (ca. 545-Ma) shallow marine sequence as mentioned in this paper.

TL;DR: In this paper, the authors evaluated two hypotheses for the origin of the 87Sr/86Sr anomalies in the Ediacaran limestones from Saudi Arabia: low temperature scenario with isolated oceans or lakes in proximity to a mafic source and high temperature scenario by juvenile hydrothermal fluids.
