Palynological investigation of the sediment cores from the Arabian Sea 2: Dinoflagellate cysts and acritarchs
Abstract
The present paper incorporates the study of dinoflagellate cysts and acritarchs recovered from five sediment cores from the Arabian Sea This assemblage is represented by 15 genera and 22 species Of these, 14 species belonging to 11 genera are of dinoflagellate cysts and 8 species belonging to 4 genera are of acritarchs, besides two types which could not be referred to any taxa One acritarch genus, viz., @iOrnatasphaera@@ and 3 species are new Among dinoflagellate cysts, @iHystrichosphaeridium@@ (3 spp.), @iSurculosphaeridium@@ (2 spp.), Tuberculodinium@@ (1 sp.) and @iLingulodinium@@ (1 sp.) and among acritarchs @iBaltisphaeridium@@ and @iOrnatasphaera@@ are the major elements The distribution of the various species in different cores has been discussed The assemblage has been compared with some other known quaternary assemblages A possible brackish water environment has been suggested
