• 10 July 2026The 3.5-Billion-Year-Old Cones That Still Catch LightIn the Pilbara's Dresser Formation, 3.5-billion-year-old stromatolites preserve the oldest direct evidence of life on Earth—microbial mats that built layered domes in a volcanic caldera.
• 05 July 2026The 3.5-Billion-Year-Old Cones That Still Breathe in the SunHow 3.5-billion-year-old stromatolites at Shark Bay are not fossils but living structures—and what they reveal about the dawn of oxygen on Earth.
• 26 June 2026The 1.6-Billion-Year-Old Breath That Rusted a ContinentHow 1.6-billion-year-old stromatolites in the McArthur Basin released enough oxygen to turn Northern Territory sandstones into red beds—the first great rusting of the Australian interior.
• 26 June 2026The 1.7-Billion-Year-Old Microbe That Nearly Ate a ContinentHow 1.7-billion-year-old stromatolites in the Northern Territory's McArthur Basin created the world's oldest zinc-lead deposit—a metal reef built entirely by microbes.
• 20 June 2026The 3.5-Billion-Year-Old Sea That Never DriedHow the Pilbara's 3.5-billion-year-old Dresser Formation preserves Earth's earliest known hydrothermal vent system, where life may have first gained a foothold.
• 20 June 2026The Copper That Rained from a 1.6-Billion-Year-Old Sky: South Australia's Mount Gunson CopperHow 1.6-billion-year-old sediments in South Australia's Mount Gunson region trapped copper from hydrothermal fluids, creating a deposit where the metal is concentrated in ancient stromatolite reefs.

• 18 June 2026The Fault That Opened a 2.5-Billion-Year-Old Window: Western Australia's North Pole DomeHow 3.5-billion-year-old seafloor in Western Australia's Pilbara Craton preserves Earth's oldest known fossils, stromatolites built by microbes before the continents had stabilised.
• 21 May 2026The Sandstone That Preserved a Ghost Coast: Western Australia's Shark Bay StromatolitesHow living microbial mats in Shark Bay, Western Australia, build stromatolites that mirror Earth's oldest fossils—and how the bay's hypersaline waters preserve a 3.5-billion-year-old way of life.
• 20 May 2026The Ash That Recorded a Continent's Birth: Western Australia's Warrawoona ChertHow 3.5-billion-year-old chert beds in Western Australia's Pilbara region preserve Earth's oldest direct evidence of volcanic activity and microbial life, recording the planet's earliest habitable env
• 20 May 2026The Kimberley Lava That Froze a Reef in TimeHow a 1.8-billion-year-old flood basalt in Western Australia's Kimberley region entombed Earth's oldest known barrier reef, preserving stromatolite columns in volcanic rock.
• 19 May 2026The Ash That Gave Birth to Breath: Western Australia's 2.5-Billion-Year-Old Stromatolites of the Fortescue GroupHow 2.5-billion-year-old stromatolite reefs in Western Australia's Fortescue Group record Earth's earliest known large-scale oxygen production, built by microbial communities before the Great Oxidatio
• 18 May 2026The Lake That Breathed Iron: Western Australia's Hamersley Banded Iron FormationsHow 2.5-billion-year-old iron-rich layers in Western Australia's Hamersley Range record Earth's first great oxygenation event, laid down by ancient microbes in a sea without life.
• 17 May 2026The Kimberley's Living Crust: Australia's 1.8-Billion-Year-Old Microbe ColonyIn Western Australia's Kimberley region, the stunning rock art of the Napier Range is painted on fossilised microbial mats that once covered a 1.8-billion-year-old Proterozoic seafloor.
• 13 May 2026The Stromatolite City: Shark Bay's Living ReefsIn Western Australia's Shark Bay, living stromatolite mounds built by microbes grow today much as they did 3.5 billion years ago, offering a rare window into Earth's earliest life.
