The Ancient Paiwalla

Ancient sandstone cliffs, embedded with fossils, tower over the wetland.
​
Between ten and five million years ago sea-levels fell, revealing sandstone formations such as those in the Mannum Formation found at Paiwalla.

Subsequent erosion has created these cliff faces which contain large deposits of sea urchins (Lovenia forbesi) deposited on the sea-bed up to twenty-three million years ago and fossilised over time.
