Abstract: During the course of a monographical study of the Cretaceous-Paleocene Germav-Formation in SE Turkey numerous speciemens of two newspecies of the Forminiferal genus Lockhartia were encountered, both ofthem characteristic index-fossils for a special horizon. The first species:Lockhartia daviesi ten Dam n, sp. is the typical Lockhartia in the mainLockhartiahorizon in the upper part of the Paleocene portion of the Germav Formation. The second species: Lockhartia ramanae ten Dam n. sp.is a typical form in the basal part of the Maestrichtian portion of the Germav Formation and in shaly intercalations in the Maestrichtian OrbitoidalLimestone.To facilitate future work in the genus Lockhartia, complete synonymyand data on occurence, as well as a series of characteristic axial sections aregiven in this paper.
