Abstract

A dorsal vertebra of an ichthyosaur is described from the fluvial deposits of the Kama River (Votkinsk District, Udmurt Republic, Russia). This vertebra belonged to a fairly large ichthyosaur about 5–6 m long, apparently one of the largest ichthyosaurs known from European Russia. The find is redeposited, and it is problematic to establish its exact age: most likely, the vertebra was brought by the Kama River from Jurassic–Cretaceous outcrops located upstream.
