                             Serravallian ICS Stage
 
                   From 13.65 +/- 0.05 To 11.608 +/- 0.005 Ma
 
  Start Defined By:  Near lowest occurrence of nannofossil Sphenolithus 
     heteromorphus, and within magnetic polarity chronozone C5ABr.
  End Defined By:  Last common occurrences of the calcareous nannofossil 
     Discoaster kugleri and the planktonic foraminifer Globigerinoides 
     subquadratus.  Associated with the short normal-polarity subchron C5r.2n.
