Seeley each gave them a separate species name: O. simus, O. woodwardi, O. oxyrhinus, O. carteri, O. platyrhinus, O. sedgwickii, O. crassidens, O. capito, O. eurygnathus, O. reedi, O. cuvieri, O. scaphorhynchus, O. brachyrhinus, O. colorhinus, O. dentatus, O. denticulatus, O. enchorhynchus, O. xyphorhynchus, O. fittoni, O. nasutus, O. polyodon, O. tenuirostris, O. machaerorhynchus, O. platystomus, O. microdon, O. oweni and O. huxleyi, thus 27 in total. As yet Seeley did not designate a type species. When Seeley published his conclusions in his 1870 book The Ornithosauria, this provoked a reaction by the leading British paleontologist of his day, Sir Richard Owen. Owen was not an evolutionist and he therefore considered the name Ornithocheirus to be inappropriate; he also thought it was possible to distinguish two main types within the material, based on differences in snout form and tooth position — the best fossils consisted of jaw fragments. In 1874, he created two new genera: Coloborhynchus and Criorhynchus. Coloborhynchus (meaning "maimed beak") which comprised a new type species called Coloborhynchus clavirostris, as well as two other species reassigned from Ornithocheirus: C. sedgwickii and C. cuvieri. Criorhynchus (meaning "ram beak") consisted entirely of former Ornithocheirus species: the type species, Criorhynchus simus, and furthermore such as C. eurygnathus, C. capito, C. platystomus, C. crassidens and C. reedi. Seeley did not accept Owen's position. In 1881 he designated O. simus the type species of Ornithocheirus and named a new separate species called O. bunzeli. In 1888, Edwin Tulley Newton reassigned several existing species names into Ornithocheirus, which created new combinations: O. clavirostris, O. daviesii, O. sagittirostris, O. validus, O. giganteus, O. clifti, O. diomedeus, O. nobilis, O. curtus, O. macrorhinus and O. hlavaci. He also reassigned the species O. umbrosus and O. harpyia into Ornithocheirus, which were formerly species given to the genus Pteranodon by Edward Drinker Cope back in 1872. In 1914 Reginald Walter Hooley made a new attempt to structure the large number of species. Hooley synonymized Owen's Criorhynchus to Ornithocheirus, in which he also sunk Coloborhynchus into that genus, meaning that the only generic name he kept was Ornithocheirus. To allow for a greater differentiation, Hooley created two new genera, again based on jaw form: Lonchodectes and Amblydectes. The genus Lonchodectes (meaning "lance biter") consisted of the former species Pterodactylus compressirostris, and Pterodactylus giganteus, which were reassigned as Lonchodectes compressirostris, the type species, and Lonchodectes giganteus, in addition, Hooley also
