| Summary: | The genus Cyrtodaria belongs to the family Hiatellidae of the des-modont pelecypods. It comprises only two living species; C. siliqua (Spengler, 1793) and C. kurriana Dunker, 1862, but several extinct species have been described. The recent species are discussed and their recent distribution, ecology, and fossil occurrences are dealt with. The fossil occurrences in Greenland are thoroughly discussed, and it is maintained that in Greenland C. siliqua has been met with only in interglacial deposits. It is concluded that C. siliqua did not spread northwards to West Greenland during the Holocene climatic optimum, as stated by some authors. The species was driven south-wards to the Newfoundland- Nova Scotia- Cape Cod area due to |
