About Argentinosaurus:
As you may have guessed from its name, the remains of Argentinosaurus were dug up in present-day Argentina, in South America. To date, researchers haven't found an entire skeleton, but what they have found--four-foot long vertebrae and five-foot-long tibiae--indicate that Argentinosaurus was a truly titanic sauropod (hence its classification in some circles as a titanosaur).
Interestingly, the remains of Argentinosaurus were dug up near the fossils of another huge dinosaur--the carnivorous theropod Giganotosaurus. This has led paleontologists (and TV producers) to speculate that packs of Giganotosaurus may have hunted down full-grown Argentinosaurus adults--a chase that would have been deadly for any smaller creatures that happened to get in the way! (By the way, paleontologists in India have uncovered the remains of a possible titanosaur, Bruhathkayosaurus, that may have been even bigger than Argentinosaurus; the trouble is, no one is exactly sure what type of dinosaur this was!)
