Pleistocene Epoch
From 1.806 +/- 0.005 To 0.01143 +/- 0.00013 Ma
Start Defined By: Just above top of magnetic polarity chronozone C2n
(Olduvai) and the extinction level of calcareous nannofossil Discoaster
brouweri (base Zone CN13). Above are lowest occurrence of calcareous
nannofossil medium Gephyrocapsa spp. and extinction level of planktonic
foraminifer Globigerinoides extremus.
End Defined By: Excatly 10,000 Carbon-14 years BP. Near the end of the
Younger Dryas cold spell.
Start Based On: Gradstein, Ogg, Smith, _A Geologic Time Scale 2004_
End Based On: CALIB Radiocarbon Calculator version 4.4 using INTCAL98
calibration curve.
