Abstract: This study covers the systematic descriptions of two groups which have been found in the benthic foraminifera assemblage of the Paleocenel Eocene aged outcrops in the Western Pontids. The first group constitutes some stratigraphically significant species (Cuvillierina sireli İnan, Kathina selveri Smout, Alveolina (Glomalveolina) lepidula Schwager, Alveolina corbarica Hottinger, Alveolina minervensis Hottinger, Alveolina ilerdensis Hottinger, Assilina placentula (Deshayes), Nummulites burdigalensis de la Harpe, Assilina exponens (Sowerby), Discocyclina scalaris (Schlumberger) an the second group contains species (Alveolina cuspidata Drobne, Opertorbitolites transitorius Hottinger, Opertorbitolites latimarginalis Lehmann, Miscellanea minuta Rahaghi, Discocyclina fortisi fortisi (d` Archiac), Discocyclina archiaci (Schlumberger) bartholomei (Schlumberger), Orbitoclypeus ramaraoi (Samanta), Orbitoclypeus ramaraoi ramaraoi (Samanta), Orbitoclypeus ramaraoi (Samanta) crimensis Less, Nemkovella strophiolata strophiolata (Gümbel), Asterocyclina stella (Gümbel) taramellii (Munier & Chalmas) whose existence in Turkey has firstly been established.
