The name Paynita is proposed for a new dagmaritin genus from the upper Changhsingian (Permian) carbonates of the Southern Biofacies Belt in Turkey. Paynita permotaurica differs from its ancestor Paradagmarita monodi by a hook-shaped fold in the apertural flap terminating systematically against the inner surface of the septal wall to protect the opening from one chamber to the other. It is associated with several species of dagmaritins, belonging to Paradagmarita, Paradagmacrusta, Louisettita, Dagmarita, Danielita, and Bidagmarita. The overall analysis of dagmaritins reveals that the stratigraphic range of the group is from Wordian to Changhsingian. The revised chronostratigraphy in the type area of the genus Sengoerina indicates that this oldest dagmaritin was derived from Globivalvulina cyprica in the Wordian. The first occurrences of genera Dagmarita and Danielita postdate the first occurrence of Sengoerina in the Wordian. Paynita is the last evolutionary step of the Sengoerina-Dagmarita-Crescentia-Paradagmarita lineage characterized by a planar apertural flap whose structure practically remained unchanged during the process of evolution. Paynita is the first genus in this lineage displaying fold in the apertural flap similar to the evolution of Louisettita from Dagmarita.

Sengoerina argandi, n. gen., n. sp., and its position in the evolution of Late Permian biseriamminid foraminifers Altıner, Demir (JSTOR, 1999-06-01) The name Sengoerina is proposed for a new biseriamminid genus characterized by a coiled stage of initially globular to progressively angular, biserial chambers followed by an uncoiled stage of angular, biserial chambers. Unlike Dagmarita, it has a distinct coiled stage and lacks spine-like projections at the outer margins of the chambers. Sengoerina constitutes the root stock of the angular-chambered, dagmaritin-type biseriamminids which evolved from the globivalvulines in the Late Permian.
Silurian Graptolite, Conodont and Cryptospore Biostratigraphy of the Guluc Section in Eregli, Zonguldak Terrane, NW Anatolia, Turkey Sachanski, Valeri; Göncüoğlu, Mehmet Cemal; Lakova, Iskra; Boncheva, Iliana; Demiray, Gulnur Saydam (2012-01-01) The studied Guluc section of the Silurian Findikli Formation is situated on the western bank of Guluc Creek in Eregli, NW Anatolia, Turkey, in the eastern part of the Zonguldak Terrane. The Guluc section consists of 3 sedimentary packages: greenish grey limy siltstones, 5-7 m thick (1), overlain by an irregular alternation of black shales and clayey limestones, about 15 m thick (2), and a 6-7 m thick succession of mainly siltstones and sandy limestones (3). A combined biostratigraphy based upon graptolites,...
Metamorphism in the Palaeozoic schists of the Southern Menderes Massif field petrographic textural and fabric data from Selimiye Milas Muğla area Bozkurt, Erdin (1996-01-01) Abstract: The Menderes Massif is a large-scale metamophic core-complex in western Anatolia and forms the western of two large metamorphic culminations in the Turkish Alpide orogen. Within the Southern Menderes Massif on the southern side of the Beßparmak Mountain north of Selimiye (Milas-MuÛla), two distinct lithologic groups are recognized on the basis of their lithology and structural position: the late Oligocene granitoid rocks now in the form of mylonitic augen gneiss and the structurally overlying sequ...
Pseudophleum anatolicum, a New Endemic Species of Pseudophleum (Poaceae) from East Anatolia, Turkey Doğan, Musa; Sinan, Ali (2015-07-01) Pseudophleum anatolicum (Poaceae: Poeae), a new species collected from Bingol Province in East Anatolia, Turkey, is described and illustrated as the second species of the genus ever discovered. The new species is distinguished from Pseudophleum gibbum by its larger spikelets and floral parts, rather longer acuminate ligules and anthers, as well as its phytogeography.
Middle-Late Triassic radiolarian cherts from the Arkotdag m lange in northern Turkey: implications for the life span of the northern Neotethyan branch TEKİN, UĞUR KAĞAN; Göncüoğlu, Mehmet Cemal; Pandolfi, Luca; Marroni, Michele (2012-09-01) Moderately to well-preserved, relatively diverse Middle and Late Triassic radiolarian assemblages have been obtained from the chert slide-blocks within the Late Cretaceous melange of the IntraPontide Suture Zone at the Pelitoren village to the NE of Kastamonu-Arac in northern Central Anatolia. In this locality, chert slide-blocks are tectonically overlain by metamorphic sole of the serpentinized peridotites belonging to the IntraPontide ophiolites. The oldest radiolarian assemblages, with the middle Late An...
