Abstract The Maastrichtian carbonates of the Tarbur Formation from the Zagros zone (SW Iran) are very rich in larger Foraminifera. Additionally, smaller benthic Foraminifera occur as well, one of them presented here as Covidaria pinnata n. gen., n. sp. It occurs abundantly at the Mandegan section within two levels corresponding to the lower photic zone. Based on the existence of a central pile along with an umbilical plate, and the lacks of true interiomarginal apertures, likely represented by a perforate surface, the suprageneric placing of Covidaria n. gen. remains controversial. The ultimate aperture is represented by a central elongate double-bifid slot that arguably lies on a finely perforated and heavy feathered apertural face. Based on the reduced dimensions and lack of dimorphism the new taxon could be considered an epifaunal or shallow-infaunal r-strategist.

Tarbur组（伊朗，扎格罗斯地区）的一种神秘的马斯特里赫特小型底栖有孔虫

摘要 扎格罗斯地区（伊朗西南部）塔布尔组的马斯特里赫特碳酸盐岩富含较大的有孔虫。此外，也会出现较小的底栖有孔虫，其中一种在此处被称为 Covidaria pinnata n。gen., n. sp. 它大量出现在 Mandegan 部分，在对应于较低光区的两个级别内。基于中央桩和脐带板的存在，以及缺乏真正的边缘间孔（可能由穿孔表面表示），Covidaria n 的上位放置。将军 仍然存在争议。最终孔径由中央细长的双裂槽代表，可以说位于精细穿孔和厚羽毛的孔径面上。
