Plutoniosaurus is an extinct genus of ophthalmosaurid ichthyosaur from the Early Cretaceous (late Hauterivian) of the vicinity of Ulyanovsk, European Russia.

Taxonomy[]

The holotype is UPM 2/740, a partial skeleton.^[1]

Plutoniosaurus is possibly the same species as the nearly coeval Simbirskiasaurus.^[2] Zverkov and Efimov (2019) recover Plutoniosaurus in the polytomy with the Platypterygius type species and Leninia.^[3]
