Editing Neoproterozoic (section)

==Subdivisions==
Neoproterozoic time is subdivided into the [[Tonian]] (1000–720 Ma), [[Cryogenian]] (720–635 Ma) and [[Ediacaran]] (635–538.8 Ma) periods.<ref name="StratChart 2022"/>

===Russian regional timescale===
In the regional timescale of Russia, the Tonian and Cryogenian correspond to the Late [[Riphean (stage)|Riphean]]; the Ediacaran corresponds to the Early to middle Vendian.<ref name="Craig2015">{{cite web | url=https://www.geosoc.fr/liens-docman/conferences/2015/les-roches-meres-petrolieres/1073-global-climate-the-dawn-of-life-and-the-world-s-oldest-petroleum-systems/file.html | title=Global Climate, the Dawn of Life and the Earth's Oldest Petroleum Systems | date=26 November 2015 | access-date=15 March 2019 | author=Craig, J.}}</ref> Russian geologists divide the Neoproterozoic of [[Siberia]] into the {{anchor|Mayanian}}'''Mayanian''' (from 1000 to 850 Ma) followed by the {{anchor|Baikalian}}'''Baikalian''' (from 850 to 650 Ma).<ref name='Khomentovsky2008'>{{cite journal
