About Antarctosaurus:

The "type fossil" of the titanosaur Antarctosaurus was discovered on the southernmost tip of South America; despite its name, it's unclear if this dinosaur actually lived in nearby Antarctica (which, during the Cretaceous period, had a much warmer climate). It's also unclear if the handful of species discovered so far belong to this genus: one specimen of Antarctosaurus measures about 60 feet from head to tail, but the other, at over 100 feet, rivals Argentinosaurus in size. In fact, Antarctosaurus is such a jigsaw puzzle that scattered remains found in India and Africa may (or may not) wind up being assigned to this genus!
