Janenschia is the oldest of the giant titanosaurs, and it may have been the largest. Unfortunately, only part of one leg has ever been discovered. Based the bones that were found, however, scientists have estimated that it may have been more than 100 feet (30 m) long and it would have weighed more than 70 tons (63,000 kilos).

This dinosaur has gone through a number of name changes since its discovery in 1907. Originally called Gigantosaurus because of its size, it was later called Tornieria and finally named Janenschia in 1991. It raises questions about whether the titanosaurs came from Africa or South America.
