Abstract: A new genus Anatoliacodium (Halimedaceae, Green algae) is described from the Ilerdian-Cuisian shallow-water sediments of Eskisehir region, central-western Turkey. These sequences consist of limestones, clayey limestones, sandy limestones and claystones. Anatoliacodium gen. nov. is characterized by erected calcareous segments with well differentiated inner structure: prevailing with large medulla of more or less densely set parallel filaments and cortical zone of prevailing horizontal to subhorizontal cortical filaments, once branching and without constriction. It is supposed that poorly and rarely preserved noncalcareous structures on the skeleton surface could be reproductive structures. The type species of the new genus is Anatoliacodium xinanmui gen. nov. sp. nov. A further new species is also described: Anatoliacodium merici gen. nov. sp. nov. Finally Gymnocodium nummuliticum Pfender, 1966 is emended and transferred to the genus Anatoliacodium.
