Scientists find evidence for an ancient supercontinent that covered 80 percent of Earth's surface
7+ hour ago (1128+ words) Ancient crust buried beneath modern mountains suggests Gondwana once contained about 80% of Earth’s continental landmass. (CREDIT: Wikimedia / CC BY-SA 4.0) Hundreds of millions of years after Gondwana broke apart, enormous pieces of the ancient landmass may still be hiding beneath some…...
Thawing Permafrost Is Releasing Carbon, but Something Unexpected Happens
7+ hour, 48+ min ago (797+ words) Much of the ancient carbon released from thawing Arctic permafrost appears to end up trapped in seabed sediments rather than quickly returning to the atmosphere. The Arctic’s frozen ground holds an enormous reservoir of organic carbon. As permafrost thaws and…...
Florida dumped half a million oyster shells into the Gulf of Mexico. No one expected the results to be this good.
14+ hour, 56+ min ago (336+ words) Dumping trash into the ocean seems like a bad idea, right? Wrong. Between 2007 and 2024, Florida attempted to rebuild the Gulf of Mexico’s ecosystem in an unusual way: dumping over 500,000 tons of recycled oyster and clam shells straight back into the…...
Melting Arctic glaciers creating climate 'doom loop' by releasing ancient methane
2+ day, 13+ hour ago (885+ words) (Gabrielle Kleber / SWNS) Melting Arctic glaciers are creating a climate “doom loop” by flushing out ancient methane from rocks beneath the ice, reveals new research. The more glaciers melt, the more of the greenhouse gas they are likely to release…...
Why is this 560-million-year-old fossil so rare?
4+ day, 19+ hour ago (648+ words) One of the oldest known 3D animal fossils dating back 560 million years has been found in a sheep field. The astonishing discovery of the creature that looked like a "goo-filled bag" when it was alive was made in northern Norway. Scientists…...

Scientists have discovered one of the oldest known three-dimensionally preserved fossils in…...
Gondwana Was Earth's Largest Supercontinent, and It Sparked the Cambrian Explosion
3+ day, 12+ hour ago (228+ words) The 75% threshold itself, meanwhile, was always somewhat arbitrary. Joseph Meert, a paleogeographer at the University of Florida who established that threshold in 2012, has acknowledged as much. "A lot of people have taken it to be a significant exact number, and…...
800 million years old - Scientists discover 'fingerprints' of supercontinent Gondwana in ancient rocks
3+ day, 17+ hour ago (286+ words) Gondwana is an ancient continent which scientists have now confirmed was a supercontinent that spread over 80 per cent of the landmass on Earth. They found 25,000 ancient rocks, and AI helped them determine that they belonged to Gondwana 500 million years ago....
