土耳其陶里德斯中部哈迪姆地区晚石炭世和早二叠世的fusulinoideans共鉴定出61种，隶属于31属。它们在生物地层学上被划分为十一个带，从上到下依次是：在Kasimovian的Protriticites variabilis，Montiparus umbonoplicatus和Schwageriniformis Schwageriniformis带;在Jigulites aff. Gzhelian期的Paraschwagerina sp.和Dutkevalina complexata带; Sakmarian期的Paraschwagerina pseudomira和Robustoschwagerina nucleo lata带; Dunbarula？sp.可能为Artinskian时代。根据对这些fusulinoideans的动物群分析，由于侵蚀和/或非沉积作用，缺失了Basal Kasimovian地层、Kasimovian-Gzhelian边界地层和下Asselian地层。在所描述的物种中，本文新提出的是Eoparafusulina brevis，Robustoschwagerina hadimensis，Pseudoschwagerina globosa和Pseudoschwagerina ozguli。E. brevis被认为与Monodiexodina谱系沿着E. ferganica。R. hadimensis代表了该属的一种小型形式。球形拟球孢菌具有独特的小黑麦型幼生体，其外观类似Sphaeroschwagerina，表明它是来自Asselian Pseudoschwagerina的特化后代. P. ozguli与大多数已知的Pseudoschwagerina种的区别在于其较小的测试和它的出现来自Sakmarian。
Sixty-one species assignable to 31 genera of Late Carboniferous and Early Permian fusulinoideans were distinguished from the Hadim area, central Taurides, Turkey. They are biostratigraphically divided into eleven zones in ascending order: Protriticites variabilis , Montiparus umbonoplicatus and Schwageriniformis schwageriniformis zones in the Kasimovian; the Jigulites aff. formosus , Daixina asiatica and Rugosofusulina sp. A zones in the Gzhelian; Paraschwagerina sp. and Dutkevichia complicata zones in the Asselian; Paraschwagerina pseudomira and Robustoschwagerina nucleo lata zones in the Sakmarian; and the Dunbarula ? sp. zone of possible Artinskian age. Basal Kasimovian strata, Kasimovian-Gzhelian boundary strata and lower Asselian strata are missing due to erosion and/or non-deposition on the basis of faunal analysis of these fusulinoideans. Among the described species, newly proposed herein are Eoparafusulina brevis , Robustoschwagerina hadimensis , Pseudoschwagerina globosa , and Pseudoschwagerina ozguli . E. brevis is thought to be phylogenetically related to the Monodiexodina lineage along with E. ferganica . R. hadimensis represents a small form of the genus. P. globosa showing Sphaeroschwagerina -like appearance has a distinct Triticites -type juvenarium suggesting a specialized descendant derived from an Asselian Pseudoschwagerina . P. ozguli is distinguished from most of known species of Pseudoschwagerina by its smaller test and its occurrence from the Sakmarian.
