                               Zanclean ICS Stage
                         (Zanclian, Tabianian, Dacian)
 
                    From 5.332 +/- 0.005 To 3.6 +/- 0.005 Ma
 
  Start Defined By:  Top of magnetic polarity chronozone C3r, ~100 kyr before 
     Thvera normal-polarity subchronozone (C3n.4n).  Calcareous nannofossils -- 
     near extinction level of Triquetrorhabdulus rugosus (base Zone CN10b) and 
     the lowest occurrence of Ceratolithus acutus.
  End Defined By:  Base of magnetic polarity chronozone C2An (Gauss); 
     extinction levels of planktonic foraminifers Globorotalia margaritae and 
     Pulleniatina primalis.
