Each unit of the Phanerozoic (542 Ma to Present) and the base
11、of Ediacaran are defined by a basal Global Standard Section and Point (GSSP ), whereas Precambrian units are formally subdivided by absolute age (Global Standard Stratigraphic Age, GSSA). Details of each GSSP are posted on the ICS website (www.stratigraphy.org).Numerical ages of the unit boundaries
12、in the Phanerozoic are subject to revision. Some stages within the Cambrian will be formally named upon international agreement on their GSSP limits. Most sub-Series boundaries (e.g., Middle and Upper Aptian) are not formally defined.Colors are according to the Commission for the Geological Map of t
13、he World (www.cgmw.org). The listed numerical ages are from A Geologic Time Scale 2004, by F.M. Gradstein, J.G. Ogg, A.G. Smith, et al. (2004; Cambridge University Press) and “The Concise Geologic Time Scale” by J.G. Ogg, G. Ogg and F.M. Gradstein (2008).This chart was drafted by Gabi Ogg. Intra Cam

Base of the Pleistocene is at 1.81 Ma (base of Calabrian), but may be extended to 2.59 Ma (base of Gelasian). The historic “Tertiary” comprises the Paleogene and Neogene, and has no official rank.
