FORAMINIFERAL DESCRIPTION OF THE MIOCENE SHALLOW-WATER LIMESTONE FROM THE DIYARBAKIR AND SIIRT AREAS OF SOUTHEAST TURKEY

This study presents the descriptive palaeontology of two very shallow-water Miocene successions with benthic foraminifera located in the DiyarbakirSiirt region of southeastern Turkey. Two rows of apertural foramina and alternating Y-shaped septula with supplementary chamberlets were identified. As a result, Borelis curdica (Reichel) was transferred to Praebullalveolina Sirel and Acar as Praebullalveolina curdica (Reichel). Furthermore, two Holocene archaiasinid genera, Androsina Levy and Cyclorbiculina Silvestri, of the new species were described and figured as Cyclorbiculina minima n. sp. and Androsina diyarbakirensis n. sp. from the very shallow-water Miocene limestone of the Derge section. The Oligocene hauerinid species Sivasina egribucakenssis Sirel and Ozgen-Erdem and Sivasina batmanensis n. sp. were also defined from the shallow-water Miocene limestone of the Derge and Baysu sections.
