Gusicella SCHLAGINTWEIT & RASHIDI, 2021 (type species Dictyoconella minima HENSON, 1948), Upper Cretaceous Larger Benthic Foraminifer and its species

Abstract

Based on new material from the middle to upper Cenomanian Natih Formation (members A and B) from Oman, the little-known species Gusicella minima (Henson), originally described from the Mish­rif Formation of Qatar (Dukhan wells) is redescribed. Late Maastrichtian specimens from the Tar­bur Formation of SW Iran previously assigned to the Cenomanian species display a more complex mar­gin­al zone and are therefore introduced as Gusicella complexa Schlagintweit & Rashidi sp. nov. Rep­re­sent­atives of Gusicella have so far only been reported from the Arabian Plate, showing its endemic char­acter. There is no record of the genus so far from the Turonian to early Maastrichtian interval.
