Fossil remains for this Dinosaur
have been found in South America
Argyrosaurus might have been the biggest dinosaur ever, but not
enough fossil bone has yet been found to know for sure.
It was among the last of the giant titanosaurs, dying out in the
great extinction at the end of the Cretaceous. Argyrosaurus's upper
leg bone of was over 6 feet (2 m) long! Unfortunately, not much more
of this dinosaur has been found.
First described in 1893, Argyrosaurus was unquestionably a huge
titanosaur. Although other material has been found that may belong
to this genus, no definitive association has yet been made.
