  Eozoic \E`o*zo"ic\, a. [See Eozo["o]n.] (Geol.)
     Of or pertaining to rocks or strata older than the Paleozoic,
     in many of which the eozo["o]n has been found.
     [1913 Webster]
  
     Note: This term has been proposed for the strata formerly
           called Azoic, and is preferred especially by those
           geologists who regard the eozo["o]n as of organic
           origin. See Arch[ae]an.
