Two New Species of Genus Acanthocythereis Howe of Ostracoda from Akashat Formation (Early-Late Paleocene) of Western Iraq.


Two new Trachyleberid Ostracoda species of genus Acanthocythereis Howe, 1963 from Akashat Formation (Early-Late Paleocene) of western Iraq. Acanthocythereis (Canthylocyereis) akashatensis sp. nov., and Acanthocythereis (Canthylocyereis) anahensis sp. nov. Species of this genus are short ranging, relatively abundant and very useful stratigraphically in W. Iraq and good markers of the top of the Paleocene, because their last occurrences are at the extreme top of it.
