Originally described as a species of Ophthalmosaurus (O. chrisorum) a 2010 study saw the specimens elevated to the level of a distinct genus of ichthyosaur. Arthropterygius was also considered to be similar to Caypullisaurus, but not all researchers have followed this and instead treat Arthropterygius as a basal (primitive) member of the Ophthalmosauridae.
