    What happened during the Ediacaran period?
    The supercontinent Pannotia formed and broke apart by the end of the period. The Ediacaran also witnessed several glaciation events, such as the Gaskiers and Baykonurian glaciations. The Shuram excursion also occurred during this period, but its glacial origin is unlikely.

    Why is the Ediacaran period important?
    The Ediacaran Period [635 to 539 million years (Ma) ago] is a pivotal period in Earth history, archiving the rise of complex macroscopic life (1). This evolutionary milestone occurred in the aftermath of extreme climate perturbations, the Cryogenian snowball Earth events (2), and amid several perturbations to the carbon cycle.

    How old was the Ediacaran period in South Australia?
    The dating of the rock type section of the Ediacaran Period in South Australia has proven uncertain due to lack of overlying igneous material. Therefore, the age range of 635 to 538.8 million years is based on correlations to other countries where dating has been possible.

    Does the Ediacaran period overlap with the Vendian period?
    The Ediacaran Period overlaps but is shorter than the Vendian Period (650 to 543 million years ago), a name that was earlier, in 1952, proposed by Russian geologist and paleontologist Boris Sokolov.
