URL: http://www.stratigraphy.org/ICSchart/ChronostratChart2018-07.pdf The utility of ICS International Chronostratigraphic Charts (ICS Charts) relies on the accuracy and precision of reported geochronologic dates and their relationship to the bases of global chronostratigraphic units. However, an examination of some early Paleozoic dates (i.e., Cambrian-Ordovician boundary and lowest Ordovician) on the ICS ...If a relationship between the Laplandian Glacial Period (600–580 Ma) and the negative excursions EN2 and EN3 on the δ 13 C curve for the Doushantuo Formation of China is established, the Vendian might take its place in the Standard Global Chronostratigraphic Chart as a formal upper series of the Ediacaran System.

Recommended For You Shift in weaning age supports hunting-induced extinction of Siberian woolly mammoths.The Gelasian is an age in the international geologic timescale or a stage in chronostratigraphy, being the earliest or lowest subdivision of the Quaternary Period/System and Pleistocene Epoch/Series. It spans the time between 2.58 Ma (million years ago) and 1.80 Ma. It follows the Piacenzian Stage (part of the Pliocene) and is followed by the Calabrian Stage.
