Argentinosaurus must have been a truly enormous creature-among the most gigantic animals ever to walk on earth. Sadly, so far it is known only from a few leg bones, several of which are more than 1 m long.
Reconstructed models suggest that Argentinosaurus was a typical sauropod with a small head, a long neck and a long tail. Closely related dinosaurs feature a sloping head, peg-like teach and front limbs shorter than back ones. These creatures belong to a family of large sauropods from South America and possibly Africa. The forelimbs are longer than those of Diplodocus and the head is rather squarer in shape.
