 On land, various archosaurian reptiles remained dominant.The Jurassic was a golden age for the large herbivorous dinosaurs known as the sauropods—"Camarasaurus", "Apatosaurus", "Diplodocus", "Brachiosaurus", and many others—that roamed the land late in the period; their foraging grounds were either the prairies of ferns, palm-like cycads and bennettitales, or the higher coniferous growth, according to their adaptations.The smaller Ornithischian herbivore dinosaurs, like stegosaurs and small ornithopods were less predominant, but played important roles.
