Abstract

Phenacophragma oezeri n. sp. (phylum Foraminifera, family Mayncinidae) is described from the Albian shallow-marine limestones of the Geyik Daği area, Central Taurides, S Turkey. It is characterized by a lenticular, completely involute test with eight to nine wedge-shaped chambers in the last whorl rapidly increased in height and by an areal and small slit-like aperture. It occurs in benthic foraminiferal wackestone/packstone and grainstone microfacies with gastropods, rudists and dasycladalean algae, in association with mainly Protochrysalidina elongata, Pseudonummoloculina aurigerica, Pseudonummoloculina heimi, Mayncina bulgarica, Mesorbitolina gr. texana, Cuneolina sliteri, Cuneolina parva, Akcaya minuta, and Akcaya auruncensis. This new species differs from the type species Phenacophragma assurgens in having a completely involute and lenticular test with less numerous chambers in the last whorl. It can be distinguished from the accompanied Mayncina bulgarica by its more axially compressed lenticular shape and its wedge-shaped (rather than falciform) chambers.

土耳其南部Geyİk Daği地区Albian浅海碳酸盐中的一种底栖有孔虫

Phenacophragma oezeri n. sp.(有孔虫门，有孔虫科)来自土耳其南部中部Taurides的Geyik Daği地区的Albian浅海石灰岩。它的特点是透镜状的，完全渐开线试验，在最后一个螺旋上有8到9个楔形室，高度迅速增加，有一个面积小的狭缝状孔径。它发生在底栖有孔虫微相/包岩和颗粒岩微相中，与腹足类、粗生藻类和浅生藻类共生，主要与Protochrysalidina elongata、Pseudonummoloculina aurigerica、Pseudonummoloculina heimi、Mayncina bulgarica、Mesorbitolina gr. texana、Cuneolina sliteri、Cuneolina parva、Akcaya minuta和Akcaya auruncensis共生。这个新种与模式种的不同之处在于在最后一个轮上有一个完全渐开线和透镜状的试验，室数较少。它可以通过其轴向压缩的透镜状形状和楔形(而不是镰状)腔室与伴随的宝格丽斑区分开来。
