Foraminiferal, nannoplankton, dinocyst, spore and pollen studies of the Tithonian-Berriasian deposits of the Tonas reiver basin have resulted in their biostratigraphic subdivision. The upper Tithonian foraminiferal Anchispirocyclina lusitanica - Melathrokerion spinalis Zone is characterized by correspondent foraminiferal assemblage. The lower Berriasian Protopeneroplis ultragranulatus -Siphoninella antique Zone is characterized by two associations. Two nannoplankton Zeugrhabdotus embergeri and Lithraphidites carniolensis Zones have been recognized in the upper Tithonian and lower Berriasian correspondingly. The late Tithonian and early Berriasian palynocomplexes have also been identified. The study of dinocysts has resulted in recog-nition of the upper Tithonian Gochteodinia villosa (Gvi) Zone and the lower Berriasian Pseudoceratium pelliferum (Pp) Zone.
