A prehistoric croc measuring more than five metres long – dubbed the ‘swamp king’ – ruled south eastern Queensland waterways only a few million years ago.

North America had Tyrannosaurus rex, South America had Giganotosaurus carolinii, and in Africa there was Spinosaurus aegyptiacus, but massively proportioned predatory dinosaurs have not featured in Australia’s prehistoric past. That is, until now.

An international research team has been stunned to discover that some crocodile-like reptiles walked on their hind legs like dinosaurs and measured over three metres in length.
