Abstract

The Karakaya Complex in northern Turkey is classically subdivided into two units (Upper and Lower Karakaya Complex) and located in the Sakarya Composite Terrane. The Upper Karakaya Complex includes different blocks and tectonic slices within a Triassic matrix. A new genus of miliolid foraminifera (Cornuspiroidea, Neodiscidae) is established from the late Capitanian (latest Guadalupian) neritic limestone block from the Upper Karakaya Complex. The new genus Globidiscus is characterized by a large, inflated lenticular in the axial and subglobular in transverse section and involute test with well-developed flosculinisation and a porcelaneous wall with buttresses. It was probably derived from the Praeneodiscus-Neodiscus lineage in late Capitanian (Guadalupian).

Globidiscus n. gen.(有孔虫目，新蠓科):土耳其西北部卡拉卡亚杂群瓜达卢普晚期一新属

土耳其北部的卡拉卡亚杂岩通常被划分为两个单元(上卡拉卡亚杂岩和下卡拉卡亚杂岩)，位于萨卡里亚复合地层中。上卡拉卡亚杂岩包括三叠纪基底内的不同块体和构造片。从上卡拉卡亚杂岩的卡皮塔尼亚晚期(最新瓜达卢普期)浅海石灰岩块中建立了一个新属(角虫总科，新蠓科)。新属球状花的特征是轴向呈大的膨大透镜状，横切面呈近球状，渐开线试验具有发育良好的花形和带扶壁的瓷质壁。它可能来源于晚期凯比塔尼亚(瓜达卢普尼亚)的praeneodius - neodiscus谱系。

期刊介绍： The Journal of Micropalaeontology (JM) is an established international journal covering all aspects of microfossils and their application to both applied studies and basic research. In particular we welcome submissions relating to microfossils and their application to palaeoceanography, palaeoclimatology, palaeobiology, evolution, taxonomy, environmental change and molecular phylogeny. Owned by The Micropalaeontological Society, the scope of the journal is broad, demonstrating the application of microfossils to solving broad geoscience issues.
