Coiling initially glomospiral and finally planispiral. Spherical proloculus, 0.087 –0.100 mm in diameter, followed by second chamber slowly enlarging in height through whorls. Initial part consists of at least 15–17 whorls, thin-walled and tightly coiled. In the terminal part (5–8 whorls) the height of the chamber increases gradually. Adult specimens measure: D = 2.08–3.25, w = 1.88–3.00 mm, the ratio w/D = 0.74–1.04, n.w. = 20–25. Wall calcareous, porcelaneous with perforations (comb teeth-shaped). The lumen of the tube is relatively high with frequent flosculinisation in adult stage. Aperture simple, terminal.ForaminifersSampleIllustrationsKDY –1KDY–2–1KDY–2Neoschwagerina craticulifera• Fig. 4A–BNeoschwagerina pinguis• Fig. 4CNeoschwagerinasp. • Fig. 4DYabeinasp. • Fig. 4EChusenella tieni• Fig. 4FPostkwantoella goekcehueyuekensis• Fig. 4GLeella armenica• Fig. 4H–ICodonofusiellasp. • Fig. 4JKahlerinasp. • Fig. 4KNankinella orientalis• • Fig. 4L–MNankinella acuta• • Fig. 4N–ONankinellaaff.chongyangensis• Fig. 4PNankinellasp. • Fig. 4QReichelinasp. • Fig. 4R–SGlobivalvulina vonderschmitti• Fig. 5AGlobivalvulina cyprica• Fig. 5B–CCharliella rossae• • Fig. 5D–ESengoerina argandi• Fig. 5FParaglobivalvulina mira• Fig. 5G–HRetroseptellina decrouezae• Fig. 5IDagmarita chanakchiensis• Fig. 5J–LHemigordius schlumbergeri• Fig. 5MCornuspira kinkelini• Fig. 5NCornuspirasp. • Fig. 5OCalcivertellasp. • Fig. 5PGeinitzinasp. • Fig. 5QNodosinelloides camerata• Fig. 5RPachyphloiasp. • Fig. 5SLangellasp. • Fig. 5TRobuloides lens• Fig. 5URectostipulina quadrata• Fig. 5V–WRectostipulina hexamerata• Fig. 5XKamurana bronnimanni• Fig. 6A–BGlobidiscus flexus• Fig. 6C–DGlobidiscus fragilis• Fig. 6E–GBaisalina akasakensis• • Fig. 6H–LBaisalinasp. • Fig. 6MComparisonRectogordiopsis kamuranaeformis gen. et sp. nov. differs from K a murana bronnimanni by the planispiral involute coiling without any oscillation.Microfossil associationThe associated foraminiferal fauna is listed in Table 1 and illustrated in Figs 4–6.Range and distributionMiddle Permian (late Capitanian) of the Elmada&gbreve; Olistostrome, Ankara City, Central Türkiye.
