Contectopalatus was a primitive ichthyosaur, an extinct fish-like marine reptile from the Middle Triassic of Germany. It was originally named Ichthyosaurus atavus (Quenstedt, 1851/52), and later Mixosaurus atavus (Quenstedt 1852). It was recognised as a valid genus by Maisch and Matzke in 1998, though other authorities argue that it is synonymous with Mixosaurus. It was 5 metres long.
