Life restoration of the large, Middle Triassic Nevadan ichthyosaur Cymbopsondylus petrinus. This illustration is primarily based on specimen UCMP 9950, with much of the tail restored following UCMP 9947. The size of the eye was reconstructed based on UCMP 9954 and UCMP 9913. The unknown distal portions of the flippers, as well as some of the tail, was reconstructed after the related genus Xinminosaurus. References Merriam, J. C.
