Ampelosaurus is now the best known sauropod from Europe. Others include Magyarosaurus from Hungary and an unnamed species from Catalonia, Spain. Numerous other fragments and isolated bones may or may not belong to any of these forms (Le Loeuff, 1995). While most Titanosaurs are found in the southern continents of Gondwanda, several derived species are known from Maastrichtian sediments in the Northern Hemisphere, including Alamosaurus in North America and Opisthocoelicaudia in Asia, indicating that there must have been at least intermittent connections between the northern and southern continents. This seems to be corroborated by the European find of Tarascosaurus, a Late Cretaceous theropod dinosaur similar to the Abelisaurids, otherwise known only from the southern continents (Le Loeuff & Buffetaut, 1991).
