A few million years later, during the Callovian-Oxfordian, from China much larger species are known, with long, "graviportal" (adapted for moving only in a slow manner on land due to a high body weight) hindlimbs: "Chungkingosaurus", "Chialingosaurus", "Tuojiangosaurus" and "Gigantspinosaurus". Most of these are considered members of the derived Stegosauridae. "Lexovisaurus" and "Loricatosaurus", stegosaurid finds from England and France of approximately equivalent age to the Chinese specimens, are likely the same taxon. During the Late Jurassic, stegosaurids seem to have experienced their greatest radiation. In Europe, "Dacentrurus" and the closely related "Miragaia" were present. While older finds had been limited to the northern continents, in this phase Gondwana was colonised also as shown by "Kentrosaurus" living in Africa. No unequivocal stegosaurian fossils have been reported from South-America, India, Madagascar, Australia, or Antarctica, though. A Late Jurassic Chinese stegosaurian is "Jiangjunosaurus". The most derived Jurassic stegosaurians are known from North-America: "Stegosaurus" (perhaps several species thereof) and the somewhat older "Hesperosaurus". "Stegosaurus" was quite large (some specimens indicate a length of at least seven metres), had high plates, no shoulder spine, and a short, deep rump.
