Cyclostomatous Bryozoa from the Paleocene and Maestrichtian of Majunga Basin,Madagascar

Fourteen cyclostomatous Bryozoa from theMajunga Basin, Madagascar, are described. Seven of these (Diastopora madagascarensis, Pustulopora bonamaryi, Filisparsa majungensis, Canalipora cylindrica, Idmidronea bombetokensis, Pseudotervia delicatula, Lichenopora betsibokensis) are new. One new genus, Serpentipora, is described.Eleven cyclostomatous species are found in the Maestrichtian. Four of these occur also in Europe. Eight species are found in the Paleocene. Two of these occur also in Europe. The bryozoan fauna is composed of thin, delicate, erectly growing species, which suggests that the Bryozoa have probably lived in a moderately deep water, approximately 100–200 m deep.
