Category:Quaternary

From Wikipedia, the free encyclopedia

The main article for this category is Quaternary.

The Quaternary Period is the geologic time period from the end of the Pliocene Epoch roughly 1.8-1.6 million years ago to the present. The Quaternary includes 2 geologic subdivisions -- the Pleistocene and the Holocene Epochs.

In a recent revision of the international classification of geological time periods, the Quaternary was subsumed into the Neogene. The move has met with much resistance from geologists, also because the 'final' ratification by the International Geological Congress of the status of the Quaternary was scheduled in 2008. Because the discussions in the International Stratigraphical Commission have not been finalized, this hierarchical repositioning was rather premature. Until this ratification has been taken place, the Quaternary is not part of the Neogene.

This category contains events which happened in the Quaternary, a division of the geologic time scale. See geologic time scale for information about its divisions and how they relate to each other.
