Antarctosaurus by Moondawg

Antarctosaurus (pronounced as ; meaning "southern lizard") is a genus of titanosaurian sauropod dinosaur from the Late Cretaceous Period of what is now South America.

Antarctosaurus was very large, even for a dinosaur. Scientists still have much to learn about Antarctosaurus, as a complete skeleton remains elusiveAntarctosaurus was a huge quadrupedal herbivore with a long neck and tail. It was possibly armored. As Antarctosaurus is not known from a complete skeleton[1] 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.

Remains of this dinosaur were first mentioned in print in 1916, although they were not fully described and named until a 1929 manuscript written by paleontologist Friedrich von Huene. Antarctosaurus does not refer to the continent of Antarctica, since it was first found in Argentina, although it does have the same derivation, from the Greek words anti- meaning 'opposite of', arktos meaning 'north' and sauros meaning 'lizard'. The generic name refers to the animal's reptilian nature and its geographical location on a southern continent.r
