Summary: | The Ilerdian–Middle Cuisian sedimentary succession of the Seyitgazi region, southern Eskişehir (Central Anatolia, Turkey) is composed of claystones, limestones and clayey limestones. It contains abundant benthic foraminifera, particularly species of
Alveolina. From this succession, 28 species of
Alveolina d’Orbigny are described and their comparative stratigraphic distribution with the
Alveolina species in the Tethyan Eocene is documented. Generally, Ilerdian–Cuisian
Alveolina assemblages of the Seyitgazi region have close affinities with coeval
Alveolina assemblages described in different studies from the Tethyan Province. The Ilerdian unit of the study area is characterized by
Alveolina species such as
Glomalveolina lepidula,
Glomalveolina minutula,
G. karsica,
Alveolina vredenburgi,
A. ellipsoidalis,
A. avellana,
A. aff. minervensis,
A. dedolia,
A. moussoulensis,
A. subpyrenaica,
A. laxa,
A. aragonensis,
A. varians,
A. ilerdensis,
A. trempina,
A. citrea,
A. pisella and
A. decipiens. Likewise, the Early Middle Cuisian unit is represented by
G. minutula,
A. oblonga,
A. schwageri,
A. haymanensis,
A. canavarii,
A. aff. coudurensis,
A. ruetimeyeri,
A. muscatensis,
A. cremae,
A. bayburtensis and
A. lehneri. |
