In 1842 Richard Owen pointed out that von Meyer had been incorrect in changing the original specific name and created the correct combination "Streptospondylus rostromajor" for "Streptospondylus altdorfensis". At the same time he created a second species: "Streptospondylus cuvieri" based on a single damaged vertebra from the Bajocian, found near Chipping Norton. In 1861, Owen would refer the entire Cuvier material to "S. cuvieri", despite the fact that if it were cospecific the name "S. rostromajor" would have priority. From that time "S. cuvieri" was generally accepted in the literature as the valid name, though some workers split off the theropod remains from the crocodilian bones, Edward Drinker Cope in 1867 naming a "Laelaps gallicus" and Friedrich von Huene in 1909 a "Megalosaurus cuvieri".
