Sea levels were around 150m higher than today but also Australia sat in Gondwanaland lower on the crustal formation forming the inland sea.
100 million years ago, the red heart of Australia didn't exist.
Where you see desert today — the cracked earth, the endless red dust, the silence — there was an ocean. A cold, shallow, murky sea that split the continent in two and stretched across one-third of Australia.
It was called the Eromanga Sea.
Massive marine reptiles hunted beneath its surface. Plesiosaurs glided through freezing waters. Kronosaurus — a predator the size of a bus — ruled these depths. And all of this was happening right over what is now the dead center of the outback.
The sea vanished around 95 million years ago. It left behind opals, fossils, and the Great Artesian Basin — the underground water system that still feeds the Australian interior today.
The desert you see now? It's just the floor of a forgotten ocean.
