Baykonurian glaciation

The Baykonurian glaciation is a glacial episode dating to around the Proterozoic–Phanerozoic boundary – precise dates are difficult to constrain but 547 million years ago has been proposed — and thus posited as a contributor to the Cambrian explosion. Its deposits are known in regions of Asia and Africa, and it apparently affected both palaeohemispheres.[1][2][3][4]
