(Table 1) Abundance of Pleistocene dinoflagellate cysts in ODP Site 133-820

Compared with other Australian marine Quaternary locations, Site 820's dinoflagellate cyst assemblages are low in both abundance and diversity. Abundances are between < 1 and 14 cysts/cm3 , and the number of species is between 7 and 14 per sample. The dominant species are Operculodinium israelianum, Spiniferites bulloideus, Spiniferites hyperacanthus and Tuberculodinium vancampoae, which together usually make up more than 75% of the assemblage.
