On Paleogeographical Distribution and Morphological Features of the Orhitoides gruenhachensis Papp in the Tethyan Ocean of Maastrichtian (Late Cretaceous)

Abstract: In this study, paleo geographical distribution and morphological features of Orbitoides gruenbachensis Papp in TethyanOcean is presented. The indicated species was found first time in Austria. The occurrence of Orbitoides gruenbachensis Pappin the Middle and Western parts of the Pontids and the northern part of the Helenid-Torid platforms indicates that thementioned species lived in a restricted area and preferred a shallow paleoenvironment having low salinity and temperature.Besides, its appearance in the Maastrichtian deposits both A ustria and Turkey also shows that its range has a resticted time.
