Abstract

Paleogene genus Orbitolites (family Soritidae) was found in Armenia as well as in former USSR firstly. The largest species O. cotentinensis Lehmann prevails in population of this genus in Rind section of Southern Armenia. The systematic description of three species of discovered Orbitolites is given. The aсcompanying assemblage of larger benthic foraminifera allowed to define the stratigraphic position of layers with Orbitolites in lower Priabonian, SB18C subzone. Distribution of Orbitolites and miliolids show on back-reef lagoon paleoenvironment, unusual for Priabonian of Southern Armenia.
