Contectopalatus was originally described as a species of Ichthyosaurus, the type genus of the Ichthyosauria that in the early days of palaeontology was treated as a catch all wastebasket taxon for any and all ichthyosaur fossils. Later study saw Ichthyosaurus atavus assigned to the Mixosaurus genus upon the grounds of overall similarity to the genus Mixosaurus. The fossils of Mixosaurus atavus however were of an ichthyosaur that was significantly larger than other Mixosaurus fossils, and a 1998 study by Maisch and Matzke saw these fossils established as a new ichthyosaur genus, Contectopalatus. Others have questioned this new genus since it was named, though at the time of writing Contectopalatus is still widely regarded as a distinct genus. The main reason for this is that the skull of Contectopalatus has a distinctly higher sagiital crest than Mixosaurus.
