Data from the Adilcevaz Formation show a strong similarity to occurrences from Southeast Asia in that they include Cycloclypeus, Eulepidina, and "ribbed" Nephrolepidina, an assemblage not previously recorded from age-equivalent deposits in the circum-Mediterranean region. The association and the occurrences of these taxa in Lower Miocene deposits from the Indo-West Pacific areas have been widely reported. The species designation of Nephrolepidina and Eulepidina, in the absence of well-demonstrated comparable biometric and conflicting stratigraphic data from the Indo-West Pacific areas, is usually problematic. The Turkish taxa bear a close resemblance to N. sumatrensis and E. formosa, whilst Cyclocypeus is represented by C. eidae, which is widespread in the Indo-Pacific Early Miocene. These taxa are accompanied by Miolepidocyclina burdigalensis, a well-documented side branch of the main Miogypsina lineage in the circum-Mediterranean region; Miogypsina globulina, a worldwide tropical species common to both provinces; and Operculina complanata. Our data provide the first foraminiferal evidence from Turkey suggesting a main westward migration of several important groups from Southeast Asia to the eastern Mediterranean during the (early) Burdigalian. This faunal incursion is the most significant compared to other Late Oligocene-Early Miocene foraminiferal events in Turkey.</dc:description> <dc:identifier>https://aperta.ulakbim.gov.trrecord/39373</dc:identifier> <dc:identifier>oai:zenodo.org:39373</dc:identifier> <dc:rights>info:eu-repo/semantics/openAccess</dc:rights> <dc:rights>http://www.opendefinition.org/licenses/cc-by</dc:rights> <dc:source>JOURNAL OF FORAMINIFERAL RESEARCH 39(1) 23-39</dc:source> <dc:title>FIRST RECORD OF THE CO-OCCURRENCE OF WESTERN TETHYAN AND INDO-PACIFIC LARGER FORAMINIFERA IN THE BURDIGALIAN OF THE MEDITERRANEAN PROVINCE</dc:title> <dc:type>info:eu-repo/semantics/article</dc:type> <dc:type>publication-article</dc:type> </oai_dc:dc>
