Feb 19th, 2026 - One fossil's teeth are forcing scientists to rethink where dinosaurs began. A small fossil jaw rests in Argentina's national natural science museum in Buenos Aires. The fossil, only six inches long, carries backward-curving teeth shaped for gripping prey. Paleontologist Martín Ezcurra says the teeth resemble "those of the fearsome Komodo dragon." The bone belonged to Lewisuchus admixtus , a reptile that lived 236 million years ago, during the Triassic . Roughly 1.5 meters long, it likely ... [Read More]

Feb 19th, 2026 - For the first time in 80 years, a rare and endangered marsupial has been rediscovered in Australia's Piccaninny Plains Wildlife Sanctuary at Cape York. The rare marsupial in question is the northern quoll, which has been listed as endangered by IUCN . Due to a long absence, experts assumed it had vanished from the area. However, it shocked everyone when it was detected on a motion-sensor camera at the facility. The news was made public by the establishment on January 5 through an Instagram post ... [Read More]

Feb 19th, 2026 - Symbiotic bacteria living inside insect cells have lost much of their DNA over hundreds of millions of years, much like the ancient microbes that evolved into mitochondria Symbiotic bacteria living inside insect cells have the smallest genomes known for any organism. The findings further muddy the distinction between cellular organelles like mitochondria and the most barebones microbes in nature. "Exactly where this highly integrated symbiont ends and an organelle starts, I think it's very ... [Read More]

Feb 19th, 2026 - A fast-moving ancient crocodile ancestor gets a name honoring the physics teacher who inspired its discoverer. In the Late Triassic, some 215 million years ago, the region we now know as the southwestern United Kingdom looked nothing like the rolling green hills of today. It was a rugged, arid archipelago of limestone islands, baking under a hot sun and surrounded by subtropical seas. If you were standing on one of those ancient uplands, you might have seen a creature that defied modern ... [Read More]

Feb 18th, 2026 - Follow Earth on Google Scientists report the discovery of a giant sauropod dinosaur, Tongnanlong zhimingi – Late Jurassic giant from southwestern China estimated at up to 92-feet-long. The fossil was found in Chongqing's Tongnan District, part of the Sichuan Basin, and comes from rocks laid down about 147 million years ago. Tongnanlong zhimingi is known from a holotype (the single name bearing reference specimen) with three back vertebrae, six tail vertebrae, a shoulder girdle, and ... [Read More]

Feb 18th, 2026 - Lovingly nicknamed "sea gooseberry," it glides through waters like a squishy crystal or a blimpy iridescent water balloon. It has been observed in deep ocean trenches and coastal waters across the world and has also been spotted in the Black, North, and Baltic Seas. The moment this gelatinous creature is removed from the water, it collapses almost instantly, disappearing like it never existed. For years, this made things difficult for the scientists who keenly desired to witness this creature ... [Read More]

Feb 18th, 2026 - Follow Earth on Google When fungi spread through a fallen log, they leave behind a web of tiny threads that quietly break down wood and recycle nutrients. For a long time, scientists assumed most of that network simply stayed behind as the fungus moved on. But new research shows that some forest fungi don't just grow forward – they tear down and reuse large parts of their own threadlike networks as they expand. Instead of abandoning old growth, they pull nutrients back in and redeploy ... [Read More]

Feb 18th, 2026 - Follow Earth on Google A lizard with a protruding nose has been found again in Peru after vanishing from science for 150 years. Its return forces quick decisions about protecting the last forest pockets where it still survives, before logging, farming, and road building shrink those pockets beyond recovery. Confirming the lost species Field teams found the lizard in a humid mountain forest in Peru's San Martin region, on a steep trail. Biologist Fernando Ayala-Varela at Ecuador's National ...

Feb 18th, 2026 - Report records 65 unprovoked attacks – but annual drowning deaths in US alone exceed 4,000 The number of people killed or bitten by sharks in unprovoked attacks globally increased significantly in 2025, a report published on Wednesday has found, while a single Florida county maintained its crown as the so-called shark bite capital of the world. The International Shark Attack File , compiled by the Florida Program for Shark Research at the University of Florida, recorded 65 unprovoked ... [Read More]

Feb 18th, 2026 - Follow Earth on Google Life in the trees shaped the bodies of early primates in powerful ways. A new study shows that climbing down trees, not just climbing up, played an important role in the evolution of upright postures. By studying how modern tree-dwelling mammals move on vertical supports, researchers uncovered clues about how early primates developed their unique body structure. Tree life shaped early primates Forests contain trunks, branches, and lianas that differ in size, angle, and ... [Read More]

Feb 17th, 2026 - Deep inside a jungle in South Sulawesi, Indonesia, someone recently got her name added to the Guinness World Records (GWR) . Officials tried to hand her the certificate, but it was a struggle. It was Diaz Nugraha, wildlife guide and snake handler, who had first spotted her in December 2025. Excited to share his discovery, he reached out to his photographer friend, Radu Frentiu. Together, they travelled to the jungle to see her up close. Unrolling rolls of surveyor tape, they documented her ... [Read More]

Feb 17th, 2026 - New research reveals the hidden cooling system inside the horned dinosaur's massive skull. To build an absolute unit like Triceratops , nature had to get creative with the plumbing. While the dinosaur is famous for its three-horned combat stance, the internal anatomy of its skull has long remained a black box. To paleontologists, the sheer size of its head presented a massive thermal engineering problem. How do you keep a brain cool inside a giant, bony helmet? According to new research from ...

Feb 17th, 2026 - ANGWIN, Calif. (AP) — Jessica Allen crunched through fallen leaves among Manzanita trees hunting for something few have spotted before: the Manzanita butter clump — a rare and little-known yellow mushroom found, so far, only along North America's Western coastlines. It was last seen here in California's Napa County two years ago, and Allen, a fungi scientist, was keen to find it. But within minutes, something caught her attention. She knelt, pulled a hand lens to her eye, and peered ... [Read More]

Feb 17th, 2026 - Genetics reveal how a tiny herd thrived against the odds. In 1871, a farmer stepped off a volcanic rock in the southern Indian Ocean. For seven months, he had tried to grow crops and cows and didn't succeed. He left five or six cattle behind, not wanting to bother with them as the settlement had failed. The cows, however, had other plans. Amsterdam Island is a speck of French territory stranded between Madagascar and Antarctica. It is wind-swept, soaked in rain, and utterly ... [Read More]

Feb 17th, 2026 - Sometimes, new data raises more questions than it answers. In a recent study, University of Alaska Fairbanks paleontologist Matthew Wooller and his colleagues radiocarbon-dated what they thought were pieces of two mammoth vertebrae, only to get a whale of a surprise and a whole new mystery. At first glance, it looked like Wooller and his colleagues might have found evidence that mammoths lived in central Alaska just 2,000 years ago. But ancient DNA revealed that two "mammoth" bones actually ... [Read More]

Feb 16th, 2026 - Nautilus Members enjoy an ad-free experience. . H ave you ever wondered how an elephant can pick up something as delicate as a peanut with its massive, thick-skinned trunk? It seems a bit like trying to scoop up a single pebble with a snow shovel. Yet, elephants manage to "go from lugging logs to delicately grasping a tortilla chip" with their trunks. For proof, check out these videos from a 2017 Science study that characterized the grip forces of elephant trunk tips.   Nautilus Members ... [Read More]
