Import of building stone to the northern Black Sea region in the Middle of the 1st mil. BC according to micropaleontological analysis

The paper presents the results of micropaleontological studies of a series of stones found during the study of the pier of the ancient Greek city of Phanagoria. The samples contain Upper Turonian–Coniacian, Campanian, and Maastrichtian foraminifers characteristic of the Central Tethys zones. This makes it possible to exclude the Crimea and the North Caucasus from the possible regions of origin of the samples. It has been established that Upper Cretaceous carbonate strata similar in genesis and chronology are located on the site of the southern coast of the Black Sea near the ancient cities of Heraclea and Sinop.
