Morinosaurus
''Morinosaurus'' (meaning "Morini lizard", for an ancient people of northern France) was a genus of sauropod dinosaur from an unnamed formation of Kimmeridgian-age Upper Jurassic rocks from Boulogne-sur-Mer, Départment du Pas-de-Calais, France. It is an obscure tooth genus sometimes referred to the Lower Cretaceous English wastebasket taxon ''Pelorosaurus''.
== History and taxonomy ==
The French paleontologist H. E. Sauvage based this genus on a single worn tooth, apparently now lost, which he compared to those of ''Hypselosaurus''.〔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. ()〕 Oddly, despite illustrations of the tooth, and the implications of comparing it to a titanosaur with narrow-crowned teeth, it was included as a synonym of ''Pelorosaurus'' in two major reviews.〔Romer, A.S. (1956). ''Osteology of the Reptiles''. University of Chicago Press:Chicago 1-772. ISBN 0-89464-985-X〕〔Steel, R. (1970). Part 14. Saurischia. ''Handbuch der Paläoherpetologie/Encyclopedia of Paleoherpetology''. Part 14. Gustav Fischer Verlag:Stuttgart p. 1-87.〕 ''Pelorosaurus'', being a putative brachiosaurid, is assumed to have had broad-crowned teeth.
Age, however, was not an issue, because it was referred to the possible ''Pelorosaurus'' species ''P. manseli'' (="Ischyrosaurus"), which was also from the Upper Jurassic (the question of whether "Ischyrosaurus" or any Jurassic species should be included in ''Pelorosaurus'' at all is another issue). The most recent review considers it to be a nomen dubium without further comment.〔Upchurch, P.M., Barrett, P.M., and Dodson, P. (2004). Sauropoda. In: Weishampel, D.B., Dodson, P., and Osmólska, H. (eds.). ''The Dinosauria'' (2nd edition). University of California Press:Berkeley 259-322. ISBN 0-520-24209-2〕
Sauvage also suggested that a partial right humerus belonged to the type individual.〔
