The Giant Sauropod was an enormous dinosaur that lived on the floodplains, searching out plants to eat. Cycads and ferns were probably included in its vegetarian diet. It lived 95 million years ago, early Cretaceous.

The Giant Sauropod left footprints that are up to 1.5m wide, and scientists have estimated it was more than 45m long - perhaps bigger than any other dinosaur on Earth.

Identification

So far, we only know the Giant Sauropod by the footprints it left behind - no bones have been found. The shape of the footprints tells us that a sauropod dinosaur made them, and their size tells us how big the dinosaur was, but without actual bones to study we don't know exactly what kind of sauropod it was.

Fossils

There are fossilised footprints of the Giant Sauropod at Broome in Western Australia.
