Author: Tara Djokic, Scientific Officer, Palaeontology, Australian Museum; UNSW Sydney Hidden beneath farmland in the central tablelands of New South Wales lies one of Australia’s most extraordinary fossil sites – McGraths Flat. It dates back between 11 million and 16 million years into the Miocene epoch, a time when many of today’s familiar plants and […]

When did something like us first appear on the planet? It turns out there’s remarkably little agreement on this question. Fossils and DNA suggest people looking like us, anatomically modern Homo sapiens, evolved around 300,000 years ago. Surprisingly, archaeology – tools, artefacts, cave art – suggest that complex technology and cultures, “behavioural modernity”, evolved more […]

Our planet has experienced dramatic climate shifts throughout its history, oscillating between freezing “icehouse” periods and warm “greenhouse” states. Scientists have long linked these climate changes to fluctuations in atmospheric carbon dioxide. However, new research reveals the source of this carbon – and the driving forces behind it – are far more complex than previously […]

Some 445 million years ago, life on Earth was forever changed. During the geological blink of an eye, glaciers formed over the supercontinent Gondwana, drying out many of the vast, shallow seas like a sponge and giving an “icehouse climate” that, together with radically changed ocean chemistry, ultimately caused the extinction of about 85% of […]

In September 2023, NASA’s OSIRIS-REx spacecraft brought home a remarkable gift: the first pristine sample ever collected from a carbon-rich asteroid called Bennu. After two years of careful study in laboratories worldwide, scientists have confirmed that Bennu’s dust and pebbles contain many of the very same small molecules life on Earth relies on as its […]
