In this proposal the Cenozoic is subdivided into the Paleogene, the Neogene, and the Quaternary (that is in accordance with common use in many countries).doi:10.1130/GSAT01802A.1 This article states that Paul Crutzen, a Nobel Prize–winning chemist, proposed, because of the global environmental effects of increased human population and economic development, proposed that we had left the Holocene and had entered a new Epoch, which he called the Anthropocene.So, the Quaternary is a unit that is not outdated at all, on the contrary.The older a sample is, the less (the period of time after which half of a given sample will have decayed) is about 5,730 years, the oldest dates that can be reliably measured by this process date to around 50,000 years ago, although special preparation methods occasionally permit accurate analysis of older samples.Biostratigraphy does not directly provide an absolute age determination of a rock, but merely places it within an interval of time at which that fossil assemblage is known to have coexisted.Both disciplines work together hand in hand, however, to the point where they share the same system of naming rock layers and the time spans utilized to classify layers within a stratum.

The base of the Quaternary should be the base of the Gelasian, that is assigned at its GSSP.
