The Order Lagenida is a monophyletic group of calcareous foraminifers that originated in Middle Pennsylvanian time via acquisition of hyaline-radial wall structure and loss of microgranular wall structure, the latter being characteristic of the close sister group and likely ancestor, the Fusulinida. Early lagenides are delineated into subgroups on the basis of presence or absence of partitioning within their tests. and among partitioned forms, on continuous versus discontinuous growth styles. Partitioned, discontinuously growing forms may be further delineated on the basis of test symmetry and on modifications to chamber shape and apertural complexity. Early lagenides underwent rapid taxonomic differentiation during late Moscovian and early Kasimovian time. Taxonomic differentiation was accompanied by rapid dispersal from the presumed center of origin in the midcontinent-Andean area to tropical and subtropical shelves worldwide. By Early Permian time certain lagenides were adapted to cool water paleoenvironments, as evidenced by their occurrences in high paleoatitudes and even in glaciomarine basins. Early Permian lagenides do not exhibit marked provincialism, but there is evidence for paleolatitudinal control on assemblages. The midcontinent-Andean and present Arctic areas contain similar, diverse faunas from low- to mid paleolatitudes along the western margin of Pangaea. These faunas share many elements in common with faunas from the tropical and subtropical eastern margin of Pangaea (Paleotethys). In contrast, the Europe-Urals, Siberian and Australian areas are characterized by a slightly different faunal association from mid- to high paleolatitudes in both hemispheres. Panthalssan fatmas are less well known, but seemingly contain only cosmopolitan taxa.

The Cretaceous Mardin Group carbonates in southeast Turkey: Lithostratigraphy, foraminiferal biostratigraphy, microfacies and sequence stratigraphic evolution Ozkan, Recep; Altıner, Demir (Elsevier BV, 2019-06-01) The Mardin Group strata, as a product of the Cretaceous carbonate platform developed in the northern margin of the Arabian Platform, consists of a thick sedimentary sequence composed mostly of carbonates with subordinate clastic sediments. In this study, three stratigraphic sections Turkoglu, Derik and Inisdere addressing this sequence have been investigated in terms of lithostratigraphy and biostratigraphy combined with microfacies analysis and sequence stratigraphic interpretation. A comprehensive examina...
End-Permian mass extinction of lagenide foraminifers in the Southern Alps (Northern Italy) Groves, John R.; Rettori, Roberto; Payne, Jonathan L.; Boyce, Matthew D.; Altıner, Demir (Cambridge University Press (CUP), 2007-05-01) The Permian-Triassic boundary, examined at two sections in the Southern Alps, occurs similar to 1.0 to 1.5 m above the base of the Tesero Oolite Member of the Werfen Formation in a depositionally continuous sequence of inner neritic carbonates. Lagenide foraminifers from the boundary interval comprise 27 species in 15 genera plus additional unidentified taxa, most of which became extinct during the end-Permian crisis. The only survivors were "Nodosaria" elabugae and unidentified species in Geillitzina and N...
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...
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 ...
Late Paleocene Orthophragminae (foraminfera) from the Haymana-Polatli Basin, central Turkey) and description of a new taxon, Orbitoclypeus haymanaensis Özcan, Ercan; Sirel, Ercüment; Altıner, Sevinç; Çolakoğlu, Sinan (GeoScienceWorld, 2001-12-01) A transgressive shallow-marine succession suggested as a reference-section for early Thanetian by the 'Early Paleogene working group' (IGCP 286) was studied for its orthophragminid foraminifera from Haymana-Polath Basin in central Anatolia. Orthophragminae, closely associated with Assilina yvettae and Operculina heberti, have been identified in a friable clastic-carbonate sequence which contains Glomalveolina in its different horizons. Basinal sediments with planktonic taxa overlie the shallow-water deposit...
