Abstract The standard reconstruction of species of Orbitoides d’Orbigny into a single lineage during the late Santonian to the end of the Maastrichtian is based upon morphometric data from Western Europe. An irreversible increase in the size of the

Orthophragminids from the Bartonian Fulra Limestone in Kutch, India and the coeval units in Sulaiman Range in Pakistan suggest the establishment of a significant number of endemic species in the Indian subcontinent (Eastern Tethys). Among a total of

Bartonian orthophragminids with new endemic species from the Pirkoh and Drazinda formations in the Sulaiman Range, Indus Basin, Pakistan

Autor: Nowrad Ali, Ercan Özcan, Ali Osman Yücel, Muhammad Hanif, Syed Irfanullah Hashmi, Farhat Ullah, Muhammad Rizwan, Johannes Pignatti

Publikováno v: Geodinamica Acta, Vol 30, Iss 1, Pp 31-62 (2018)

The Pirkoh and Drazinda formations in the Sulaiman Range, central Pakistan, yielded assemblages of (early) Bartonian orthophragminids, characterized predominantly by discocyclinids with a significant number of species probably endemic to Indian Subco

Atlas of the Tethyan orthophragmines

Autor: Ercan Özcan, Ali Osman Yücel, Levent Sina Erkızan, Münire Nur Gültekin, Sibel Kayğılı, Sıla Yurtsever

Publikováno v: Mediterranean Geoscience Reviews. 4:3-213

Orthophragmines are a group of discoidal, lenticular or stellate ‘orbitoidal’ larger benthic foraminifera that thrived in shallow-marine environments in low-to-middle latitudes during the late Paleocene and Eocene. They consist of two phylogeneti

The first record of genus Linderina Schlumberger (foraminifera) from the Ypresian of Neo-Tethys: data from the Kozaklı Basin, Nevşehir, Central Turkey

Autor: Recep Özkan, Şükrü Acar, Ali Osman Yücel, Ercan Özcan, Ayhan Ercan, Mehmet Ali Gül

Publikováno v: Mediterranean Geoscience Reviews. 3:253-268

The phylogenetic history of the Eocene foraminiferal genus Linderina Schlumberger, with a widespread global distribution from the Central America region to SE Asia and Australia, is little known despite numerous but yet fragmentary and non-continuous

A new, complex hyaline larger benthic foraminifer, Bigaella orbitoidiformis n. gen. n. sp., from the upper Bartonian-Priabonian of NW Turkey

Autor: Ercan Özcan, Simon F. Mitchell, Johannes Pignatti, Michael D. Simmons, Ali Osman Yücel, Natalie Robinson

The upper Bartonian–Priabonian shallow-marine deposits in the Biga Peninsula (NW Turkey) contain some hyaline larger benthic foraminifers (LBF) with a test architecture similar to ‘orbitoidiform’ foraminifers, but displaying some distinctive an

Baculogypsina Sulaimanensis N. Sp. (calcarinidae) from the Priabonian of Sulaiman Range, Pakistan: a Possible Ancestor For the Recent Baculogypsina Sphaerulata

Autor: Sibel Kayğılı, Ali Osman Yücel, Johann Hohenegger, Ercan Özcan, Nowrad Ali, Muhammad Hanif

Publikováno v: Journal of Foraminiferal Research. 49:423-433

Priabonian ‘Pellatispira-beds’ of the Drazinda Formation in Sulaiman Range, Pakistan, contain rare calcarinids displaying similar morphological traits known from Pliocene–Recent Baculogypsina (Sacco, 1893). These specimens possess a biconvex-le

Primitive Helicorbitoides (Foraminifera) and associated larger benthic foraminifera from the Campanian Tonya Formation, Trabzon, eastern Pontides, NE Turkey

Autor: Aral I. Okay, Ali Osman Yücel, Bilal Sarı, Sadıkcan Erbay, J.T. van Gorsel, Ercan Özcan

Publikováno v: Cretaceous Research. 101:30-42

The genus Helicorbitoides MacGillavry represents an evolutionary stage in the transition of rotaloidean with primary spiral chambers to the forms displaying an orbitoidal-type growth pattern in the Campanian. Unlike the widespread distribution of its
