Abstract: | Three paleosol profiles (FPS-profiles) are described from the Djadokhta Formation (Upper Cretaceous, Campanian), outcropping in the Bain-Dzak section (southern Gobi aimag, Mongolia). The new data allow the climate at the time of the formation of the Late Cretaceous FPS-profiles to be interpreted as semiarid with seasonal precipitation. The isolated fossil roots of higher plants preserved in situ in the FPS-1 profile of the Bain-Dzak section are described as a new species, Radicites gobiensis Naugolnykh, sp. nov. |
