Agglutinated foraminifera from the Campanian-Maastrichtian Kiseiba Formation in the Kurkur area, Egypt

El-Sorogy, Mohamed Youssef & Abdelbaset . 2018

The upper Campanian to upperMaastrichtian sedimentary sequence of the Kiseiba Formation in southWestern Desert is sampled and described in two surface sections (Sinn El Kaddab and Wadi Abu Siyal). Forty-four agglutinated foraminiferal species are identified from 42 samples in the studied succession. The benthic foraminiferal assemblages are dominated by agglutinated foraminifera which comprise more than 90% of the assemblage. The agglutinated foraminifera are subdivided into five morphogroups (A, B, C, D, E) according to shell architecture, integrated with the supposed microhabitat and feeding strategy. The foraminiferal assemblage is assigned to mixohaline shallow water environments. These assemblages with Ammoastuta megacribrostomoides and Ammotium bartheli suggest lagoonal environments with considerably reduced salinity in warmclimates and high runoff for the late Campanian-Maastrichtian interval.
