NOTE: Synonymy within this genus is mainly according to Galton (1984, 1985, 1998). Preliminary morphometric analysis by Weishampel & Chapman (1990) indicates that two or more species may be present. Further work is needed before they can be correctly named.

                                           neocomiensis "du Néocomien (Crétacé inférieur)"

 

NOTE: All species listed under Iguanodon atherfieldensis above have priority over that species and must be formally suppressed if the synonymy proposed by Norman (1990) is to be accepted.

 

Owen's species Cetiosaurus brachyurus (1842), Streptospondylus major (1842), Streptospondylus recentior (1851), and Streptospondylus meyeri (1854) were all based on Iguanodon material more or less indeterminate at the species level. (At the time, Streptospondylus itself was misidentified as a crocodilian; it is actually a theropod dinosaur.) France, too, entered the fray with remains unearthed by paleontologist Jacques Cornuel and described by him in 1850 as a new genus and species of dinosaur, Heterosaurus neocomiensis ("different lizard from the Neocomian": so called because its teeth differed from those of Iguanodon, Hylaeosaurus, and Megalosaurus and supposedly required a new genus. Mixed with plesiosaur teeth--the nondinosaurian "different" teeth--were the scattered bones of a medium-size Iguanodon skeleton, to date one of the best-preserved dinosaurs ever found from the Early Cretaceous of France. Briefly noted by G. Corroy in 1922, Heterosaurus neocomiensis remained largely forgotten as a doubtful taxon with a composite type specimen for more than a century, until 1968, when it was tersely redescribed by Albert F. de Lapparent and Vladimir Stchepinsky. Now stored at the Saint-Dizier Museum, Cornuel's material, as well as other French Iguanodon material, was thoroughly and completely redescribed in 1992 by Valérie Martin and Eric Buffetaut of the Université Paris. They concluded that Heterosaurus neocomiensis most closely resembles Iguanodon atherfieldensis among the currently valid species in that genus. Should this suggested synonymy be accepted, the trivial name atherfieldensis would have to be abandoned in favor of neocomiensis.

                 Régime : Herbivore

                 Epoque : Jurassique supérieur (Kimmeridgien : - 154,7 à 152,1 Ma)

                 Etymologie :    Neosodon "Nouveau type de dent"

                                           praecursor " "

 

NOTE: This genus, previously considered a synonym of Pelorosaurus, is probably a large camarasaurid, as indicated by newly discovered material from the Boulonnais in northern France (E. Buffetaut, in SVP Bulletin #158: 16; Buffetaut & Martin, 1992). Neosodon was initially described without a type species but with its own type specimen (a tooth). It seems to have been von Huene (1927) who synonymized the taxon with Iguanodon praecursor (based on a similar tooth), thereby giving this genus its type species secondarily.

 

Teeth "new kind of tooth" Named for a previously unknown, supposedly "omnivorous" type of dinosaur with teeth resembling those of both Megalosaurus and Iguanodon; actually a sauropod tooth

                                           sauvagei "de Sauvage"

 

Isolated distal caudal vertebrae of a theropod dinosaur. Named for the elongated appearance of a tail vertebra; for "Iguanodon" prestiwichi. The material was originally referred to as Iguanodon prestwichii by Sauvage (1897) but was subsequently renamed Teinurosaurus by Nopcsa (1928) and than renamed Caudocoelus sauvagei by Huene (1932) before finally being renamed Teinurosaurus sauvagei by Olshevsky (1978). The material is clearly theropod but must be regarded as a nomen dubium.
