Two New Species of The Foraminiferal Genus Lockhartia From Turkey
Öz
During the course of a monographical study of the Cretaceous-Paleocene Germav-Formation in SE Turkey numerous speciemens of two new species of the Forminiferal genus Lockhartia were encountered, both of them characteristic index-fossils for a special horizon. The first species: Lockhartia daviesi ten Dam n, sp. is the typical Lockhartia in the main Lockhartiahorizon 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 Orbitoidal Limestone.
To facilitate future work in the genus Lockhartia, complete synonymy and data on occurence, as well as a series of characteristic axial sections are given in this paper.
