                                   ABSTRACT

         A comparative study was done based on the coral genera of the  Amazon

         region in  an  attempt  to  correlate  them  with  components  of the

         Midcontinent  region during the Middle  Carboniferous.  Coral  genera

         used in  this  paper  are those of the Subclasses Rugosa and Tabulata

         from the Itaituba Formation (Morrowan), State of Para, Brazil.  Their

         distribution demonstrates  a  possible  sea  connection bordering the

         continental margins linking the Amazon and  the  Midcontinent  region

         during the  Middle Carboniferous. This hypothesis is confirmed by the

         distribution of contemporaneous brachiopods which inhabited the  same

         niche.
