Argentinosaurus
From Tardis Wiki, the free Doctor Who reference
Argentinosaurus was believed to be the biggest of the Titanosaur family of Sauropods which thrived during the late Cretaceous. The Argentinosaurus was itself around 30 metres long and weighed more than 70 tons, although some fossils suggested the existence of even bigger creatures.
