During early and late Cretaceous wide range of large reptiles-carnivores of Reptilia class, Ichthyopterygia subclass and Ichthyosauria order inhabit basins and bays of warm-water shallow epiсontinental seas situated in the separated northern coast of Mezotethys. Among Ichthyosauria fossils found are some fragments of skeletons, separate findings of skull fragments preserved to various extent, vertebrae and teeth which findings are known in Greenland, southwest of Great Britain, Parisian basin, Northern Apennines (Italy), Annopole (Poland) and Volga region (Russia). The findings of ichthyosauria teeth and vertebrae (Kaniv, Malyn, Transnistria) make it possible to fill the gap (region) between Western Europe and eastern area of the East European platform. Fossils of the latest and youngest in age ichthyosaurus (Platypterygius sp. and Platypterygius? sp.) found in Ukraine are presented by phosphatized vertebrae and teeth preserved to different extent. Ichthyosauria fossils are sampled from glauconite quartz sands of Albian and Cenomanian (Kaniv, Middle Transnistria) and basal depositions of sedimentary cover (Malyn). Lithological and stratigraphic characteristics of ichthyosauria teeth locallities of Cretaceous depositions in Ukraine are discussed.
