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. Glacial deposits possibly related to this glaciation have been found to be dated between 549 and 530 Ma.[1] It is named for the Baykonur Formation in Central Asia.[2][3][4][5]
