Sauropod
By the Upper Cretaceous, the diplodocids and brachiosaurs been replaced by the titanosaurs, which had a near-global distribution. They were larger relatives of the brachiosaurs. As with all other non-avian dinosaurs, the titanosaurs died out in the Cretaceous–Paleogene extinction event. Fossilised remains of sauropods have been found on every continent, including Antarctica.
