Ninety-one percent of calcareous foraminiferal genera became extinct during the end-Permian mass extinction. The Early Triassic Epoch was a survival phase characterized by a short-lived proliferation of disaster forms and then I prolonged interval of low diversity. The orders Miliolida and Lagenida experienced limited taxonomic re-diversification in Early and Late Anisian time, respectively. All fusulinoidean fusulinides became extinct in Late Permian time, and only two non-fusulinoidean genera persisted into the Early Triassic. Triassic fusulinides diversified to just five genera before the order became entirely extinct in Late Triassic time. Involutinides originated in Olenekian time from an unknown ancestor. They did not significantly diversify until Late Triassic time.

Wall structures in selected Paleozoic lagenide foraminifera Groves, JR; Rettori, R; Altıner, Demir (Cambridge University Press (CUP), 2004-03-01) Paleozoic lagenide foraminifera are strikingly similar morphologically to Mesozoic and Cenozoic Lagenida, but because benthic foraminifers suffered a catastrophic reduction in diversity during the end-Permian mass extinction, it is unclear whether the similarities of Paleozoic lagenides and younger unquestioned Lagenida link them evolutionarily or are the product of convergence. Seven species representing five families of Paleozoic lagenide foraminifers were examined and found to possess mostly monolamellar...
Timing of depositional regime changes during the Late Cretaceous evolution of the Southern Pontides (Ankara, Central Anatolia, Turkey) Sariaslan, Nisan; Altıner, Sevinç; Altıner, Demir (Elsevier BV, 2020-08-01) During the Cretaceous, vast amounts of marine sediments were deposited along the south-facing active margin of the Eurasia. A stratigraphic section of 91 m was analyzed for planktonic foraminifera (75 samples), with the aim of establishing a refined biostratigraphy of Cenomanian-Campanian deposits in Central Anatolia. A biostratigraphic framework comprising nine biozones was established. In ascending order, the Rotalipora cushmani, Whiteinella archaeocretacea and Helvetoglobotruncana helvetica zones were de...
Sengoerina argandi, n. gen., n. sp., and its position in the evolution of Late Permian biseriamminid foraminifers Altıner, Demir (JSTOR, 1999-06-01) The name Sengoerina is proposed for a new biseriamminid genus characterized by a coiled stage of initially globular to progressively angular, biserial chambers followed by an uncoiled stage of angular, biserial chambers. Unlike Dagmarita, it has a distinct coiled stage and lacks spine-like projections at the outer margins of the chambers. Sengoerina constitutes the root stock of the angular-chambered, dagmaritin-type biseriamminids which evolved from the globivalvulines in the Late Permian.
MAGNETOSTRATIGRAPHY AND PALEOECOLOGY OF THE HOMINID-BEARING LOCALITY, CORAKYERLER, TUGLU FORMATION (CANKIRI BASIN, CENTRAL ANATOLIA) Kaya, Ferhat; Kaymakcı, Nuretdin; Bibi, Faysal; Eronen, Jussi; PEHLEVAN, CESUR; ERKMAN, AHMET CEM; Langereis, Cor G.; Fortelius, Mikael (Informa UK Limited, 2016-03-03) Ouranopithecus turkae, from the late Miocene of Corakyerler in Central Anatolia, is considered one of the last known occurrences of great ape in the eastern Mediterranean. The Corakyerler fauna has previously been correlated with MN 11 to early MN 12 on the basis of biochronology, and its faunal composition has been found to contrast with those from contemporaneous sites. In this paper, we present the magnetostratigraphy of the Corakyerler site and an expanded interpretation of its paleobiogeographical and ...
Reconstruction of a Late Jurassic-Early Cretaceous carbonate platform margin with composite biostratigraphy and microfacies analysis (western Sakarya Zone, Turkey): Paleogeographic and tectonic implications Atasoy, Serdar Görkem; Altıner, Demir (Elsevier BV, 2018-12-01) During Late Jurassic-Early Cretaceous the Pontides were the site of a wide carbonate platform facing the Tethys ocean in the south. In the western Pontides the Upper Jurassic-Lower Cretaceous shallow marine carbonates abut the Tethyan Izmir-Ankara suture with no evidence for platform margin deposits. The Sivrihisar klippe 50 km south of the Izmir-Ankara suture preserves a record of the missing platform margin. In the Upper Jurassic-Lower Cretaceous carbonates exposed in this Sivrihisar klippe, two coeval bu...
