From: Multiple Orbitoides d’Orbigny lineages in the Maastrichtian? Data from the Central Sakarya Basin (Turkey) and Arabian Platform successions (Southeastern Turkey and Oman)

Fig. 23

Panel showing the tentative relations of Orbitoides species from the late Campanian to late Maastrichtian along the Arabian Plate margin, Turkey and Western Europe. Arrows show possible offshoots from the main Orbitoides lineage in the Maastrichtian, represented by O. ‘medius’ and O. pamiri. Orbitoides gensacicus from Gensac is not into scale. Data from Campanian and Maastrichtian type sections and from Gensac (SW France) are from van Hinte (1966b) and Eggink and Baumfalk (1983). The O. gruenbachensis population from Maurens, Spain is from Caus et al. (1996). The prefix ‘GÖ’ is for Orbitoides medius populations from the upper Campanian of the Central Sakarya Basin (unpublished data of EÖ and AOY). Details of samples HAY.W.82, 95, 115, 116 from the Haymana Basin are given in Özcan and Özkan-Altıner (1997)
