Ancient Amphibian Fossil Discovered in Australia Inspires Paleontologist's Career

A 240-million-year-old fossil of a predatory amphibian was discovered in 1996 during landscaping work on the Central Coast of New South Wales. The specimen, found in sandstone from Kincumber Quarry, was identified as a temnospondyl—an extinct amphibian group resembling a crocodile-salamander hybrid. After being displayed in the Dinosaur World Tour exhibition in Sydney, the fossil was donated to the Australian Museum in 2000. Decades later, paleontologist Lachlan Hart, who first saw the fossil as a 12-year-old, formally described it as a new genus and species named Arenaerpeton supinatus. The well-preserved fossil, which includes soft tissue impressions, provides insights into vertebrate evolution and represents a significant part of Australia's fossil heritage.
