Abstract
Three new species of Saracenaria from the Lower Cretaceous of the Ust’-Yenisei District are described. S. gerkei sp. nov. is recorded in the Valanginella tatarica, Recurvoides obskiensis Foraminiferal Zone (KF2, upper boreal Berriasian–Valanginian). S. vologochanensis sp. nov. and S. pjasinensis sp. nov. are characteristic of assemblages of the beds with Cribrostomoides infracretaceous, Cribrostomoides sinuosus (KF4, terminal Lower Valanginian–basal Hauterivian). Detailed comparisons of new species with other most closely similar morphotypes are provided.
