ABSTRACT
An ichthyosaurian skeletal remains assigned to the genera Arthropterygius and Ophthalmosaurus are described from the Volgian deposits of the Komi Republic and Nenets Autonomous Region (Okrug) (Russia). These specimens along with findings from Svalbard provide an opportunity to draw some preliminary conclusions on the distribution of ichthyosaurs during the Late Jurassic and Early Cretaceous epoch.
Key words: Arthropterygius, ichthyosaurs, Ophthalmosaurus, Russia, Upper Jurassic
