Archaeonectrus Novozhilov, 1964
Genus proposed for 'Plesiosaurus' rostratus by Novozhilov (1964) classified as a pliosauroid, sometimes within the Rhomaleosauridae. By modern standards Owen's (1865) original description is rather inadequate. One notable character is the relatively small size of the limbs relative to the the body. Archaeonectrus rostratus is the type and only species of this genus.
