Gilianelles (Microproblematics) from Late Cretaceous Deposits of Mount Polyus (Crimean Peninsula)

Gilianelles, calcareous microproblematics, representatives of the Late Campanian group of microfossils, were found for the first time in the Upper Cretaceous deposits of the interfluve of the Kacha and Belbek rivers in the Crimean Mountains. They come from deposits of the Polyus section, previously dated as Turonian–Santonian. It is proposed that the 50-m thick “calcisphere” limestones along the dirt road on the western slope of Mount Polyus to its summit (outcrop 3177) can be dated as Campanian.
