                               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.
