An Argentinian team of palaeontologists has discovered huge fossilised bones in the Antarctic.
The discovery of a titanosaur, large, plant-eating dinosaurs that roamed the planet around 70 million years ago, indicates that this type of dinosaur, notable for walking on four legs and boasting long necks, had a far wider global distribution than previously thought.
A member of the sauropod family, titanosaurs were the biggest creatures to walk the earth, and include Argentinosaurus - a 100 tonne monster - among their ranks. They were alive during the Late Cretaceous period.
The find is made up of a series of fossilised remains, including vertebrae, some more than 20cm long. However, the exact species of titanosaur has yet to be discerned.
"Our finding indicates that advanced titanosaurs achieved a global distribution at least by the Late Cretaceous," said Dr Ignacio Alejandro Cerda, from the Conicet research institute in Argentina.
