Algal-rich limestones have been identified during fieldwork at Zawali (Shameran) Mountain, Darbandikhan, Iraq. The algae
occur within an 8-m thick interval of fine-grained gray limestone in the lower part of the Khurmala Formation (Upper Paleocene-
Lower Eocene). In this area, the Khurmala Formation is 170 m thick and consists mostly of poorly fossiliferous dolomitic
lagoonal limestone. Thin intervals contain gastropods, pelecypods, foraminifers (e.g., miliolids, soritids, rotaliids, and rare
nummulitids), and calcareous green algae. One of these levels consists almost exclusively of fertile ampullae of a bornetellacean
dasycladalean alga. Here we define it a new organ-species: Frederica kurdistanensis nov. sp.
