Paraophthalmosaurus is an ophthalmosaurid ichthyosaur from the Late Jurassic of European Russia.[1]

Taxonomy

It was originally described in 1997 on the basis of remains from the Saratov region of European Russia. It was subsequently considered either valid or a synonym of Ophthalmosaurus.[2] However, recent cladistic analysis finds it to be a derived member of Ophthalmosaurinae.[3][4]
