Paleontologists put a Brazilian trackway beside one from Cameroon 3,700 miles away, and the dinosaur footprints lined up so exactly that both sets had been pressed into a riverbank that lies under the Atlantic today
7+ hour, 32+ min ago (758+ words) The rock shelf in northeast Brazil looks like nothing much. Three toes, pressed into mud that has since turned to stone, and not one print but a walking line of them across a flat slab. The awkward part is that…...
Water from 43 sites in eastern Tennessee went through a test rebuilt from museum specimens after a failed freezer erased the last usable tissue, and 3 of those samples carried slender chub DNA
2+ week, 4+ day ago (755+ words) Pull a bottle of water out of the Clinch River in eastern Tennessee and it looks like nothing at all. What is actually in it is shed skin cells, mucus and waste from everything living upstream of the bottle. A…...
They cracked open a cave sealed for a million years and found a flightless parrot, a ghostly rail, and birds that New Zealand had quietly erased from its skies long before humans arrived
1+ mon, 1+ week ago (510+ words) A cave on New Zealand’s North Island sat undisturbed for over a million years, its floor sealed between two layers of volcanic ash. When paleontologist Trevor Worthy’s team began sieving the sediment, they pulled out 21 bone fragments representing 12 bird species…...
Scientists cracked open 160-million-year-old rocks from a French riverbed and found a creature that looks almost exactly like something alive in the ocean today, and the discovery is forcing a rethink of how bodies evolve
1+ mon, 3+ week ago (791+ words) Picture the bottom of a warm Jurassic sea, roughly where southern France sits today, 160 million years before anyone built a road or planted a vineyard. Something impossibly spindly picks its way across the mud on legs so long they barely…...
Deep in the Sahara desert, a "hell heron" dinosaur crowned with a blazing scimitar crest is rewriting what we knew about spinosaurs
2+ mon, 6+ day ago (596+ words) The story of the hell heron fossil in the Sahara Desert begins like something almost mythical. The discovery of a huge fish-eating dinosaur in a place of today’s extreme heat and desolation may seem unusual at first. Yet in the…...
Human eyes evolved from a single-eyed worm that crawled the seafloor 600 million years ago, scientists now confirm
2+ mon, 1+ week ago (529+ words) Credits: Bruno Frías Morales / Wikimedia Commons Human eye evolution is hidden in something familiar—those pretty familiar-looking eyes staring right back at you when you look in the mirror. But where do they come from? They developed from a worm…...
Scientists found a hamster-sized survivor that somehow made it through the apocalypse that wiped out the dinosaurs
2+ mon, 1+ week ago (569+ words) About 66 million years ago, Earth changed suddenly when an asteroid collided with the planet. Fires burned out of control. Darkness covered everything. One by one, the world’s ecosystems began to collapse. When this massive event took place, almost three-fourths of…...
Scientists thought they knew everything strange about the platypus, until they switched on an ultraviolet light and watched it do something no one saw coming
2+ mon, 1+ week ago (730+ words) Some animals are a little strange. The platypus is in a league entirely of its own. It is a mammal that lays eggs. It has a bill like a duck, a tail like a beaver, webbed feet, and, in the…...
A 550-million-year-old fossil found along the Yangtze River may explain why Earth's earliest animals left almost no trace
2+ mon, 1+ week ago (634+ words) If Earth’s history is an epic book, we have to get by without the first few chapters. The very beginning of life as we know it is a mystery. We know that ancient organisms were evolving. And we even have…...
Scientists cracked open 300,000 ancient stones from Illinois and found three lost worlds hiding inside
2+ mon, 2+ week ago (523+ words) Locked inside hundreds of thousands of iron-carbonate nodules pulled from the Illinois soil are creatures that lived more than 300 million years ago — animals from tropical swamps, river deltas, and shallow inland seas, all frozen in stone during the Carboniferous Period....
