Timescale
This is a simplified table that does not include sub-periods, epochs, and anything within. The Theochronic Eon and the Paleoproteimeran and Mesoproteimeran eras, along with their subdivisions, are GDS2.0 original additions to the scale. The Proteimeran itself is derived from Goldblatt et. al's Prenephelean, and adjusted for Gradstein and Ogg's GTS2012 proposal including the Neochaotian Era in the Hadean as the Chaotian era, which pushed the Nephelean and Erebrean periods of the Eochaotian into the eon (the term Prenephelean would be redundant if it includes the Nephelean, and if the Nephelean isn't even its last period). The Hadean was constructed with a mixture of Goldbatt's proposals and GTS2012's, while the Archean and Proterozoic were using the GTS2012's proposals (which were not formally used, key word is proposed). The remainder of the Time Scale uses the accepted GTS2012 model, with the exception of this site accepting the Anthropocene epoch (not shown here).
