Inland sea

Did you know the largest and most fearsome creature in the Eromanga Sea was the Kronosaurus?

It had a powerful jaw full of sharp teeth and a body as long as a bus!

Gondwana and the Eromanga Sea

The Australian continent has not always been the same shape or even in the same place. It was once part of the much larger Pangaea landmass, then the great southern land of Gondwana. By the time of the dinosaurs, it was attached to Antarctica and home to the giant inland Eromanga Sea.

Dinosaurs are the best known reptiles from this era, though there were also flying reptiles called pterosaurs, and marine reptiles including plesiosaurs, none of which were actually dinosaurs.
