Stichocorys peregrina, Didymocyrtis penultima and Didymocyrtis antepenultima Late Miocene radiolarian zones are encountered from mudstone strata of Sawai Bay Formation, Neill Island, Andamans. Percentage data of forty-five coarser taxonomic groups of radiolarians were subjected to Q-mode cluster analysis. Cluster A comprises Stichocorys, Phormospyris, Eucyrtidium, Lamprocyclas, Acrosphaera and Cycladophora groups. Cluster B was divided into subclusters at 0.83 level of clustering. Subcluster B… CONTINUE READING
