Antarctosaurus

Antarctosaurus (/ænˌtɑːrktoʊˈsɔːrəs/; meaning "southern lizard") is a genus of titanosaurian sauropod dinosaur from the Late Cretaceous Period of what is now South America. The type species, Antarctosaurus 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 but later studies have indicated that none of these pertain to ''Antarctosaurus. Antarctosaurus giganteus,'' the second species, is also considered dubious but it's remains represent one of the largest dinosaurs known.

Scientists still have much to learn about Antarctosaurus, as a complete skeleton remains elusive.[1]
