Antarctosaurus
''Antarctosaurus'' (; meaning "southern lizard") is a genus of titanosaurian sauropod dinosaur from the Late Cretaceous Period of what is now South America. The type species, ''A. wichmannianus'', was described by prolific German paleontologist Friedrich von Huene in 1929, who also described a second species in 1929. Three additional species of ''Antarctosaurus'' have been named since then. Later studies indicate that none of these pertain to ''Antarctosaurus''.
''Antarctosaurus'' was very large, even for a sauropod. Scientists still have much to learn about ''Antarctosaurus'', as a complete skeleton remains elusive.〔"Antarctosaurus."

==Description==
''Antarctosaurus'' was a huge quadrupedal herbivore with a long neck and tail. It was possibly armoured. As ''Antarctosaurus'' is not known from a complete skeleton〔 and tail lengths are highly variable among sauropods, the true size of these animals is hard to extrapolate. The type species may have been over 60 feet (18 meters) long, and a second species may have been one of the largest land animals ever. ''Antarctosaurus'' may have been as tall as 15 feet at the shoulder.〔
