Marine Palynomorphs Found in Holocene Sediments off the Coast of Northwestern Kyushu, Japan

Dinoflagellate cyst assemblages from a core collected offshore of Tsukinokawa Harbour in Matsu'ura City, northwestern Kyushu are described and compared to other assemblages from around Kyushu Island. Along with the cysts, many microforaminiferal linings were found and are here discussed using an informal classification system originally developed for fossil linings. The assemblages contain a new microforaminiferal lining morphotype: Trochospiral type III which is described and illustrated. The diversity of the lining assemblages generally match those of the dinoflagellate cysts, with a higher diversity in the younger samples. The Gonyaulacoid and Tuberculodinioid dinoflagellate cysts were found to fluoresce well under ultra violet light illumination but the linings either poorly fluoresced a faint blue-grey colour or not at all
