Abstract

A new species of ichthyosaur genus Undorosaurus from the Volgian stage of Moscow is described based on an incomplete forelimb. It differs from congeners basically in the form and position of pisiforme. With the application of cladistic method the phylogenetic position of two genera Undorosaurus and Paraophthalmosaurus in the system of Ichthyosauridae is defined. Both taxa are referred to the clade Ophthalmosaurinae.

Key words
