Haematosaurus is an extinct genus of teleosaurid thalattosuchian. Fossils have been found from Boulogne-sur-Mer in northern France of Jurassic age.Sauvage, H. E. (1880). Synopsis des poissons et des reptiles des terrains jurassiques de Boulogne-sur-mer. Bulletin de la Société Géologique de France 13:524-547. It was originally thought to be a plesiosaur, and the type species was initially assigned to the genus Plesiosaurus in 1874, although it was later reassigned to the new genus in 1934.Sauvage, H. E. (1874). Memoire sur les dinosauriens et les crocodiliens des terrains jurassiques de Boulogne-sur-Mer. Mémoires de la Société Géologique de France, second series 10:1-58.Kuhn, O. (1934) Sauropterygia: Fossilia Catalogous 69:1-127. It is now known to have been a marine crocodylomorph.Sepkoski, J. J. (2002). A compendium of fossil marine animal genera. Bulletins of American Paleontology 363:1-560 Due to the fragmentary nature of the material associated with the genus, it is currently regarded as a nomen dubium.
