Hi! I have a few questions about the way the units of the geologic timescale are listed here:

  • The Quarternary has at the moment an unclear status, however, the ICS will most likely decide it to be a third period in the Cenozoic, containing two epochs: Pleistocene and Holocene. (I changed that)
  • The subdivisions of the Mississippian and Pennsylvanian epochs are only regionally used and are not recognized by the ICS. The subdivision of the Carboniferous period into stages can be seen in the timeline in the article Carboniferous.
  • The Hadean eon and its subdivisions are only used when the Moon is concerned (exept for the timescale by Harland et al 1989, which is no longer used). It should be left out. The Precambrian has no official status any longer and should also be left out.
  • Why is the Phanerozoic not put in the same level as other eons? Woodwalker (talk) 10:05, 13 June 2008 (UTC)[reply]
