Palaeoecological analysis of Berriasian ostracods of the central Crimea

Julia N. SAVELIEVA

Abstract


The author has completed a palaeoecological analysis of assemblages of ostracods, collected from the sections of the Berriasian deposits of central Crimea. The strata belonging to this stage are divided into four formations, and these into stratigraphic subdivisions of member rank, numbered 1–29. The members accumulated in deeper and shallower environments in a shallow marine basin, and are distinguished on the basis of the characteristic features of the composition of the ostracod complexes. Changes of temperature conditions and water mobility were identified.
