pedum in Namibia, Spain and Newfoundland, and possibly, in the western United States. pedum overlaps the range of the Ediacaran fossils in Namibia, and probably in Spain., a preceding stage beginning around 557 Ma with the earliest widespread Ediacaran biota fossils; two proposed schemes differ on whether the lower strata should be divided into an Early and Middle Ediacaran or not, because it's not clear whether the Shuram excursion (which would divide the Early and Middle) is a separate event from the Gaskiers, or whether the two events are correlated.The dating of the rock type section of the Ediacaran Period in South Australia has proven uncertain.The relative proximity of the Moon at this time meant that tides were stronger and more rapid than they are now.The day was 21.9±0.4 hours, and there were 13.1±0.1 synodic months/year and 400±7 solar days/year.In the late Middle Ages, Tibetan Buddhism spread into the areas south of Lake Baikal.During the Russian Empire, Siberia was chiefly developed as an agricultural province.This was also aided by the discovery and exploitation of vast reserves of Siberian mineral resources.According to Vasily Radlov, among the earliest inhabitants of Central Siberia were the Yeniseians, who spoke a language different from the later Uralic and Turkic people.

The fossil record from the Ediacaran Period is sparse, as more easily fossilized hard-shelled animals had yet to evolve.The Vendian in its type area consists of large subdivisions such as Laplandian, Redkino, Kotlin and Rovno Regional stages with the globally traceable subdivisions and their boundaries, including its lower one.The Redkino, Kotlin and Rovno regional stages have been substantiated in the type area of the Vendian on the basis of the abundant organic-walled microfossils, megascopic algae, metazoan body fossils and ichnofossils.The lower boundary of the Vendian could have a biostratigraphic substantiation as well taking into consideration the worldwide occurrence of the Pertatataka assemblage of giant acanthomorph acritarchs. 635–542 Mya) represents the time from the end of global Marinoan glaciation to the first appearance worldwide of somewhat complicated trace fossils (Treptichnus pedum (Seilacher, 1955)).Although the Ediacaran Period does contain soft-bodied fossils, it is unusual in comparison to later periods because its beginning is not defined by a change in the fossil record.
