ABSTRACT: Larger foraminifera are recognized from the middle Tertiary (Oligocene-Miocene) carbonate sediments, Bey Dalari Autochton, which is a segment of a Tethyan Platform. Eight diagnostic species and their local ranges are documented. These 8 species establish three biostratigraphically useful faunal assemblages which are assigned to Tertiary e4 (Chattian), Tertiary e5 lower (Aquitanian) and Tertiary e5 upper (Burdigalian) of the Far Eastern Letter Stages. Diagnostic miogypsinid foraminifera and one new genus, Spinosemiogypsina antalyaensis, n. gen., n. sp. are described.
