The new gonyaulacoid dinoflagellate Pentadinium galileoi Sancay et al., sp. nov. from the Oligocene-Lower Miocene sediments of Eastern Anatolia has been identified. It is spherical, chordate with prominant discoidal cingulum and distally furcate apical, sulcal, and antapical processes. It has a type P (3") archeopyle, and periarcheopyle is larger than endoarcheopyle. Tabulation is distinct and it has a formula of 1 pr, 3-4', 6",6c, 6'", 1p, 1"". Wall structure is granular in intraplate areas, and it has gonal spines at apex, posterior intercalary, and antapex. Processes at gonal positions may be on a variably developed antapical 'skirt' formed by extended septa (2-3 µm), minute bifurcate spines intergonally and along cingulum at plate intersections. Periphragm and endophragm appressed except at cingular area and at septa. The size of the cysts ranges between 73-89µm with an avarage of 84µm. [ABSTRACT FROM AUTHOR] |
