Antarctosaurus
"Antarctosaurus" was a large quadrupedal herbivore with a long neck and tail. 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 18 meters long, and a second species may have been one of the largest land animals ever. "Antarctosaurus" may have been as tall as 4.5 meters at the shoulder. It's lower jaw was squared off at the tip suggesting a specialised feeding mechanism.
