  • Systematic revision and phylogenetic assessment of the family Neodiscidae (Foraminifera) and new Capitanian foraminiferal genera from the Ankara region, central Türkiye
    Cengi̇z Okuyucu, Meli̇kan Akbaş
    European Journal of Taxonomy, 2026
    Among Paleozoic foraminifers, miliolids represent one of the most diverse groups, which reached their highest diversity during the Middle to Late Permian. Notably, many taxa within the family Neodiscidae emerged during the Guadalupian epoch. In this study, two fossiliferous Middle Permian blocks were studied for their foraminiferal assemblages around Kutludüğün Yayla (east of Ankara, Türkiye) from the Elmadağ Olistostrome. We present a systematic and phylogenetic revision of the subfamilies Neodiscinae and Agathammininae, and propose the erection of Globidiscinae subfam. nov. included within the family Neodiscidae. The foraminiferal genera Kamurana, Globidiscus, and Agathammina are taxonomically re-evaluated and emended based on newly described miliolid taxa, in conjunction with a reassessment of previously published data. The composition and taxonomic status of the subfamily Neodiscinae is revised. The subfamily Agathammininae and family Neodiscidae are emended. The genus Neodiscus derives from Praeneodiscus in the Capitanian, and Kamurana, Globidiscus, Rectogordiopsis gen. nov., Davanela gen. nov. and Kaganella gen. nov. derived probably from Neodiscus in the late Capitanian. The new taxa are Globiscinae subfam. nov.; Rectogordiopsis gen. nov.; Davanella gen. nov. and Kaganella gen. nov., Rectogordiopsis kamuranaeformis gen. et sp. nov., Rectogordiopsis ovaliformis gen. et sp. nov., Davanella ankaraensis gen. et sp. nov., Davanella acuminata gen. et sp. nov., Kaganella tekini gen. et sp. nov.
  • Upper Cretaceous foreland flysch deposits from the Neotethyan Intra-Pontide Ocean: geological and palaeontological evidence from the Elmadağ Olistostrome of Ankara, central Türkiye
    U. Kağan Tekin, Cengiz Okuyucu, Alaettin Tuncer, Melikan Akbaş, Kaan Sayit
    Lethaia, 2025
    The Ankara region of Türkiye is located on the Sakarya Continent, bounded by two Neo-Tethyan oceans (Intra-Pontide to the north and Izmir-Ankara-Erzincan to the south). In this region, the oldest lithologies of the Sakarya Continent are the Middle Triassic Dikmen Greywacke. The lower part of the Dikmen Greywacke comprises low-grade metamorphics, while its upper part is primarily represented by non-metamorphic greywacke with rare carbonates/chert interlayers and a basic volcanic breccia at the top. The Dikmen Greywacke is overlain unconformably by the Coniacian Elmadağ Olistostrome, composed of blocks of varying sizes (pebble to mega-block of 2-3km width) within a calcareous clastic to clayey carbonate matrix. Based on the benthonic Foraminifera assemblages, while detrital limestone provides a Kungurian to Changhsingian (late Early to latest Permian) age, platform carbonates yield latest Capitanian-late Changhsingian (latest Middle to latest Permian) ages. Radiolarian assemblages reveal a Changhsingian (latest Permian) age from a radiolarian chert, middle Late Ladinian (Middle Triassic) from a spiculite/radiolarian chert, latest Bajocian-early Bathonian (Middle Jurassic) from a radiolarian chert, early Hauterivian (Early Cretaceous) from a pelagic limestone, and late Hauterivian (Early Cretaceous) from a radiolarian chert. Combined geological and palaeontological evidence suggest that the Elmadağ Olistostrome has been formed in a foreland basin in front of the southwardly advancing nappes originating from the Intra-Pontide domain. The determined ages imply that the Intra-Pontide basin was rifted after the Artinskian (Early Permian), possibly during late Early Permian to latest Permian. With the gradual deepening of this basin, the first pelagic rock unit occurred in late Changhsingian (latest Permian), where platform carbonates were also present at the rim of the basin in this time interval. Due to the continuous deepening in the basin, pelagic rock units were deposited from middle Late Ladinian (Middle Triassic) to late Hauterivian (Early Cretaceous). By correlation to the other olistostrome occurrence to the south of the Ankara region, it can be suggested that the Elmadağ Olistostrome formed in the Ankara region during Coniacian (Late Cretaceous) owing to the closure of the Intra-Pontide Ocean.
  • Oncoidal Facies Across the Carboniferous-Permian Transition (Hadim Nappe, Southern Türkiye): Paleoenvironmental Implications and Correlations
    Melikan Akbaş
    Geological Journal, 2025
    The cortoid and/or oncoid‐bearing carbonates of the Girvanella Limestone Facies of the Hadim Nappe that were deposited during the early–middle Gzhelian–middle Asselian time interval are represented by a succession that laterally extends over dozens of kilometres and is up to 60 m thick. This facies is easily distinguishable from the facies above and below and is considered a significant sedimentological marker unit by its lithological properties (e.g., brownish‐red colour and large oncoids). Eight microfacies types are recognised from the Girvanella Limestone Facies: cortoid grainstone/floatstone, cortoid‐bioclastic grainstone/rudstone, cortoid‐aggregate grainstone, bioclastic grainstone to packstone, oncolite packstone/rudstone, oncoid grainstone/floatstone, mudstone/wackestone, and algal fenestral bindstone that are indicative of moderate to high‐energy shallow marine carbonate platform settings (e.g., sand shoals and bank zone and lagoon–peritidal zone). Oncoid‐bearing facies across the Carboniferous–Permian transition in the Hadim Nappe show a well correlation with similar deposits from South China, Iran, Mexico, Carnic Alps (Austria), and Japan. This widespread and synchronised deposition of the oncoid‐bearing facies corresponds to the major phase (Glacial period III) of the Late Palaeozoic Gondwana glaciation and global sea‐level drop associated with this glaciation.
  • New data on the Early-Middle Viséan (MFZ10-MFZ13) foraminifers from the Hadim Nappe, southern Turkey: Biostratigraphic implications

    Micropaleontology, 2024
    The Hadim Nappe has a relatively complete succession from the Middle(?)–Upper Devonian to Upper Cretaceous in the Taurides. The Bademli section is one of the well exposed sections of theHadim Nappe that is selected for detailed biostratigraphic investigations. It includes a continuous Viséan stratigraphic succession. In the Bademli section, rich and diverse Early-Middle Viesean foraminiferal assemblages were recovered, most of which were reported for the first time in Turkey. Four first occurrence biozones, which approximately correspond to the Zones MFZ10 to MFZ13 of the Belgium stratotype section, are identified based on the foraminiferal analysis of the Lower-Middle Viséan strata of the Bademli section that are Ammarchaediscus-Glomodiscus first occurrencezone, Uralodiscus rotundus first occurrence zone, Pojarkovella first occurrence zone and Endothyranopsis (Reitlingeropsis) intermedia - Endothyranopsis mosquensis first occurrence zone.

  • Fusulinid Biostratigraphy of the Moscovian-Lower Kasimovian of Hadim Nappe, Central Taurides, southern Turkey
    Melikan Akbaş, Cengiz Okuyucu
    Geodiversitas, 2022
    The Hadim Nappe which is one of the allochthonous tectonic units in the Tauride Belt includes continuous stratigraphic successions from Middle(?)-Late Devonian to Late Cretaceous. The well exposed successions of the Moscovian to lower Kasimovian are selected for fusulinid biostratigraphy along three sections (Yassıpınar, Gölbelen and Bademli) in the Central Taurides. The Lower-Middle Pennsylvanian boundary was determined by the first appearance datum of the Aljutovella aljutovica (Rauzer-Chernousova, 1938) and Solovievaia ovata ovata (Rauzer-Chernousova, 1938). In this study, the Vereian, Kashirian, Podolskian and Myachkovian regional substages of the Moscovian stage were determined by Aljutovella aljutovica-Solovievaia ovata ovata, Aljutovella priscoidea (Rauzer-Chernousova, 1938), Eofusulina triangula (Rauzer-Chernousova & Belyaev in Rauzer-Chernousova, Belyaev & Reitlinger, 1936), Fusulinella vozhgalensis devexa Rauzer-Chernousova in Rauzer-Chernousova, Gryzlova, Kireeva, Leontovich, Safonova & Chernova, 1951, Beedeina schellwieni (Staff in Schellwien & Staff, 1912) and Fusulinella bocki bocki Möller, 1878 in ascending order. The base of the lower Kasimovian is represented by the occurrence of Quasifusulinoides Rauzer-Chernousova & Rozovskaya in Rauzer-Chernousova & Fursenko, 1959, Protriticites Putrya, 1948 and Montiparus Rozovskaya, 1948 taxa. A total of 106 fusulinid species belonging to 19 genera were determined. One genus and ten species are new: Aljutovella typica Akbaş, n. sp., Beedeina minuta Akbaş, n. sp., Beedeina tauridiana Akbaş, n. sp., Praefusulinella guvenci Akbaş, n. gen., n. sp., Praefusulinella okuyucui Akbaş, n. gen., n. sp., Praefusulinella rhombiforma Akbaş, n. gen., n. sp., Praefusulinella tekini Akbaş, n. gen., n. sp., Fusulinella absoluta Akbaş, n. sp., Fusulinella obtusa minuta Akbaş, n. subsp. and Fusulinella propriaforma Akbaş, n. sp. The taxonomic positions of some fusulinids species (e.g., Neostaffella larionovae polasnensis (Rauzer-Chernousova & Safonova in Rauzer-Chernousova, Gryzlova, Kireeva, Leontovich, Safonova & Chernova, 1951), Depratina chernovi (Rauzer-Chernousova, Gryzlova, Kireeva, Leontovich, Safonova & Chernova, 1951), Solovievaia arta (Leontovich in Rauzer-Chernousova, Gryzlova, Kireeva, Leontovich, Safonova & Chernova, 1951) and Beedeina paradistenta (Safonova in Rauzer-Chernousova, Gryzlova, Kireeva, Leontovich, Safonova & Chernova, 1951) were revised. The fusulinid assemblages recovered in this study correlate well with the Russian Platform, Cantabrian Mountains, Central Iran, southern Urals, Donets Basin, and some other regions of the Tethyan Realm.

  • Biostratigraphy and taxonomy of fusulinid foraminifera across the Upper Mississippian (upper Serpukhovian)-Lower Pennsylvanian (Bashkirian) successions from the Hadim Nappe, Central Taurides, southern Turkey
    Melikan Akbaş, Cengiz Okuyucu
    Journal of Paleontology, 2021
    The Hadim Nappe, which is one of the allochthonous tectonic units in the Tauride Belt, in southern Turkey, includes a continuous stratigraphic succession from the Middle(?)–Late Devonian to Late Cretaceous. A relatively complete succession of the upper Serpukhovian to Bashkirian is exposed in the Central Taurides, where two sections (Yassıpınar and Gölbelen) have been selected for detailed biostratigraphic investigations. The Mississippian-Pennsylvanian boundary in these sections was determined by the first appearance datum of thePlectostaffella jakhensisand located in the oolitic limestone facies indicating a shallow-water depositional environment. The uppermost Serpukhovian and regional Bashkirian substages (Syuranian, Akavasian, Askynbashian, and Arkhangelskian) were determined by index taxa, namelyPlectostaffella jakhensis,P.bogdanovkensis,P.varvariensis,Pseudostaffella antiqua,Staffellaeformes staffellaeformis,Tikhonovichiella tikhonovichi, andVerella spicata. Fifty fusulinid species belonging to fourteen genera were determined in two sections, in which two species are new:Depratina turaniAkbaş new species andTikhonovichiella praetikhonovichiAkbaş new species. The taxonomic positions of two fusulinid species (Depratina convolutan. comb. andStaffellaeformes parva robustan. comb.) are revised. The studied fusulinid assemblages correlate with fusulinid assemblages from the southern Urals, Russian Platform, Donetz Basin, Darvaz, Spain, central Iran, and some other regions of the Tethyan Realm.UUID:http://zoobank.org/bcbb6c72-f6f9-4e77-9cf9-3572bd731ff3
