Of all the reptiles alive today, crocodiles and alligators may be the least changed from their prehistoric ancestors of the late Cretaceous period, over 65 million years ago

Between 100 million and 97 million years ago, a vast sea that covered 60 per cent of Australia – from Coober Pedy in South Australia to the Gulf of Carpentaria in northern Australia – began retreating.

This drying out of Australia’s centre increased the acidity levels at shallow depth, releasing silica through the weathering of sandtone. Further weathering then lowered the acidity to a level at which precious opal can form in the silica-rich gel.
