One hundred million years ago, during the Cretaceous period, much of northeastern Australia was underwater. The inland Eromanga Sea was home to a myriad of marine creatures, from turtles and dolphin-like ichthyosaurs to the bus-sized predator Kronosaurus queenslandicus and other plesiosaurs.
The forested outskirts of the sea were home to dinosaurs and the skies above were filled with birds. But all of them would have been shaded by the largest flying creatures of the age – the pterosaurs.
