A New Species of Angariid Gastropod from the Early Thanetian of the Haymana-Polatlı Basin, Turkey

Abstract

A new trochoidean species, Angaria calvii n. sp., from the early Thanetian of the Ki{dotless}rkkavak Formation (Haymana-Polatli{dotless} Basin, Palaeocene) in central Anatolia, is described and placed in the family Turbinidae. Previously, the oldest Cenozoic Angaria was recorded from the Early Palaeocene (Danian) in France (Paris Basin). In this paper, we report the second discovery of the oldest angariid specimens from the Thanetian sediments of the Tethys realm, a stratigraphic position which is supported by the foraminiferal-red alga assemblages at this locality. © TÜBITAK.
