    For the first time in three decades, paleontologists are about to revisit one of North America's most remarkable troves of ancient fossils: The bones of tens of thousands of animals piled at the bottom of a sinkhole-type cave. Natural Trap Cave in Wyoming is 85 feet (25 meters) deep and almost impossible to see until you're standing right next to it. Over tens of thousands of years, many, many animals—including now-extinct mammoths, short-faced bears, American lions and American cheetahs—shared the misfortune of not noticing the 15-foot-wide (4 meters) opening until they were plunging to their deaths. Now, the U.S. Bureau...

    The cave is cool and damp -- prefect for preserving prehistoric remains, Meachen says. "It's like a refrigerator in there, and probably has been for 20,000 years," she said. "Some of the bones we're finding there have collagen in them. That is where you could get the ancient DNA." The scientists saw bones falling out of a part of the cave, and decided to start digging there. "That was the fossil layer," she said. "There is so much to dig. We have two more years for funding that we can be out there, so we are going to try to...

    (Reuters) - Scientists excavating an ancient Wyoming sinkhole containing a rare trove of fossils of Ice Age mammals have unearthed hundreds of bones of such prehistoric animals as American cheetahs, a paleontologist said on Friday. The two-week dig by an international team of researchers led by Des Moines University paleontologist Julie Meachen marked the first exploration of Natural Trap Cave at the base of the Bighorn Mountains in north-central Wyoming since its initial discovery in the 1970s. Meachen said the extensive excavation that began late last month uncovered roughly 200 large bones of animals like horses that roamed North America...

    Guardian (UK) ^ | Wednesday 23 July 2014 | Ian Sample
    The collective noun is a terror of tyrannosaurs: a pack of the prehistoric predators, moving and hunting in numbers, for prey that faced the fight of its life. That tyrannosaurs might have hunted in groups has long been debated by dinosaur experts, but with so little to go on, the prospect has remained firmly in the realm of speculation. But researchers in Canada now claim to have the strongest evidence yet that the ancient beasts did move around in packs. At a remote site in north-east British Columbia - in the west of Canada - they uncovered the first known...

    The primitive folk assessed by many archaeologists as being the original native Americans – that is, the Clovis people – killed and ate the lovable prehistoric elephants that inhabited the continent alongside them, scientists say. The proto-dumbo species in question is known as the gomphothere. Until recently, it had been thought that gomphotheres had disappeared from North America well before human beings showed up, but new fossil evidence appears to show that at least one cuddly tusker was brutally killed by Clovis people around 13,400 years ago. The luckless pachyderm was then scoffed by its peckish assailants. "This is the...

    Want to find the nearest pterosaur? There's an app for that — or a database, at least. A newly developed website catalogs more than 1,300 specimens of extinct flying reptiles called pterosaurs, thus enabling users to map out the ancient creatures on Google Earth. The goal is to help researchers find trends in the evolution and diversity of these ancient winged reptiles. "Having a very specific database like this, which is just for looking at individual fossil specimens of pterosaurs, is very helpful, because you can ask questions that you couldn't have answered with bigger databases [of more animals]," said...

    Based on its huge thigh bones, it was 40m (130ft) long and 20m (65ft) tall. Weighing in at 77 tonnes, it was as heavy as 14 African elephants, and seven tonnes heavier than the previous record holder, Argentinosaurus. Scientists believe it is a new species of titanosaur - an enormous herbivore dating from the Late Cretaceous period. A local farm worker first stumbled on the remains in the desert near La Flecha, about 250km (135 miles) west of Trelew, Patagonia.

    It’s a disaster scenario that Hollywood has picked up on (think Deep Impact). An incoming object menaces the Earth. Scientists try to destroy it with nuclear weapons, but the horrified populace soon discovers that the blast has simply broken the object into pieces, each with the potential to wreak havoc planet-wide. Now we learn that an impact between two asteroids causing a similar crack-up may have resulted in the cataclysmic event some 65 million years ago that destroyed the dinosaurs. Researchers from Southwest Research Institute and Charles University (Prague) have been studying the asteroid (298) Baptistina, combining their observations with...

    Arlington, Va.—How land-living animals evolved from fish has long been a scientific puzzle. A key missing piece has been knowledge of how the fins of fish transformed into the arms and legs of our ancestors. In this week's issue of the journal Science, paleontologists Neil Shubin and Michael Coates from the University of Chicago and Ted Daeschler from the Academy of Natural Sciences in Philadelphia, describe a remarkable fossil that bridges the gap between fish and amphibian and provides a glimpse of the structure and function changes from fin to limb.

The yeast come from the surface of one of the oldest marine mammal fossils ever discovered in the western hemisphere. The idea for the beer came from Jason Osborne, who co-directs a nonprofit dedicated to advancing paleontology and geology. A paleo beer, Osborne thought, would be a great hook to interest non-scientists in fossils. I think many non-scientists are quite interested in fossils already, but I cannot argue against a paleo beer. Will whale-fossil beer really taste that different from other...

    Cat-sized reptiles once roamed what is now the icebox of Antarctica, snuggling up in burrows and peeping above ground to snag plant roots and insects. The evidence for this scenario comes from preserved burrow casts discovered in the Transantarctic Mountains, which extend 3,000 miles (4,800 km) across the polar continent and contain layers of rock dating back 400 million years. "We've got good evidence that these burrows were made by land-dwelling animals rather than crayfish," said lead researcher Christian Sidor, a vertebrate paleontologist at the University of Washington and curator at UW's Burke Museum of Natural History and Culture.

The extraordinary fossil bed contains the bones of pterosaurs - early mammals – including the first known swimming mammal with a beaver-like tail, the earliest gliding mammal and feathered dinosaurs. Their remarkably preserved remains were discovered in rocks beneath the Jehol Biota in north eastern China - a famous collection of 130 million-year-old fossils from the Cretaceous Period. The latest discovery sheds light on life in the Middle-Upper Jurassic 30million years earlier when birds are believed...

    A tiny 4.4-billion-year-old crystal has been confirmed as the oldest fragment of Earth's crust. The zircon was found in sandstone in the Jack Hills region of Western Australia. Scientists dated the crystal by studying its uranium and lead atoms. The former decays into the latter very slowly over time and can be used like a clock. The finding has been reported in the journal Nature Geoscience. Its implication is that Earth had formed a solid crust much sooner after its formation 4.6 billion years ago than was previously thought, and very quickly following the great collision with a Mars-sized body...

But the sequence also reveals that interbreeding occurred between Neanderthals and other hominin groups, including early modern humans. “Did humans evolve like a constantly branching tree?

China's famous feathered dinosaur fossils owe their exquisite preservation to volcanic eruptions between about 130 and 120 million years ago.

The Jehol deposits also preserved soft tissue from early mammals and flowering plants. Baoyu Jiang of Nanjing University, China, and his colleagues think they know why the remains are so...

    When a scientific principle is common knowledge even in grammar school, you know it has long since crossed the line from theory to established fact. That's the case with dinosaur extinction. Some 65 million years ago — as we've all come to know — an asteroid struck the earth, sending up a cloud that blocked the sun and cooled the planet. That, in turn, wiped out the dinosaurs and made way for the rise of mammals. The suddenness with which so many species vanished after that time always suggested a single cataclysmic event, and the 1978 discovery of a 112-mile,...

    The popular theory that dinosaurs were wiped out by an asteroid 65million years ago has been challenged. It was believed the Chicxulub crater in Mexico was the 'smoking gun' of the mass extinction event. Molten droplets from the ancient asteroid impact were found just below the Cretaceous-Tertiary boundary - a geological layer of sediment linked with the extinction. But soil samples from the 112-mile wide crater show the impact predates the disappearance of the dinosaurs by about 300,000 years. The latest research has been published in the Journal of the Geological Society. Study author Professor Gerta Keller from Princeton University...

    EGS-AGU-EUG Joint Assembly, Nice, April 2003 Mass-extinction controversy flares again Core from asteroid crater fuels debate on what wiped out the dinosaurs. 10 April 2003 REX DALTON [photo] The dinosaurs were wiped out 65 million years ago. © alamy.com A claim that the asteroid that struck Mexico 65 million years ago did not cause the mass extinction that wiped out dinosaurs triggered heated debate at a meeting this week. The announcement is based on preliminary analysis of the first core drilled into the 185-kilometre Chicxulub asteroid crater near the Yucatan Peninsula. Gerta Keller of Princeton University in New Jersey says...

    Just as scientists thought they had nailed down the answer, the debate has been reopened. A team of scientists claims the widely accepted theory that the extinction was triggered by a huge asteroid thumping into Mexico 65m years ago, cannot be true. Evidence that a giant asteroid impact was the cause of the dinosaurs' demise first emerged in the 1980s. Scientists analysing ancient soils in Italy found that layers of clay from the end of the Cretaceous period, the time the dinosaurs vanished, were unusually rich in a heavy metal called iridium. Later evidence of the layer was found in...

    September 15, 2003 Could an enormous volcanic eruption have killed the dinosaurs? Cardiff University -- The extinction of the dinosaurs -– thought to be caused by an asteroid impact some 65 million years ago –- was more likely to have been caused by a 'mantle plume' -– a huge volcanic eruption from deep within the earth's mantle, the region between the crust and the core of the earth. This theory, already supported by a significant body of geologists and palaeontologists, is strengthened by new evidence to be presented at an international conference at Cardiff University on 11-12 September. Research by...

    Volcanic Eruptions, Not Meteor, May Have Killed The DinosaursRajahmundry Quarry. Keller's crucial link between the eruption and the mass extinction comes in the form of microscopic marine fossils that are known to have evolved immediately after the mysterious mass extinction event. The same telltale fossilized planktonic foraminifera were found at Rajahmundry near the Bay of Bengal, about 1000 kilometers from the center of the Deccan Traps near Mumbai.

    A 65 million year old tsunami is still wreaking havoc in the scientific community, a New Mexico State University professor says. The 300-foot-tall tsunami - an aftereffect of the giant meteor impact that some scientists think killed off the dinosaurs - scrambled fossils and rock and has made the event very hard to date, said Timothy Lawton, head of NMSU's geology department.

    Scientists may have destroyed the well-established theory that a single, massive asteroid strike killed off the dinosaurs 65 million years ago. New data suggests the Chicxulub crater in Mexico, supposedly created by the collision, predates the extinction of the dinosaurs by about 300,000 years. The controversy over what killed the dinosaurs may run and run The authors say this impact did not wipe out the creatures, rather two or more collisions could have been responsible. The report is published in Proceedings of the National Academy of Sciences. An international group of scientists led by Professor Gerta Keller, of Princeton University,...
  • Asteroid Theory of Dinosaur Extinction Questioned

    Scientists probing a vast crater off Mexico's Yucatan peninsula questioned a popular theory about dinosaurs on Monday, saying the collision that formed the crater happened too far back in time to have caused their extinction by itself. Much evidence points to the idea that an asteroid or comet gouged the Earth around 65 million years ago, triggering volcanic and climate changes that eventually wiped out the dinosaurs. When the huge, mostly underwater crater was found off Yucatan, it seemed the perfect candidate. "Since the early 1990s the Chicxulub crater on Yucatan, Mexico, has been hailed as the smoking gun that...

    Dinosaur discoveries wow Boston Sensational fossil discoveries were unveiled on Monday, including the most primitive wishbone yet found in a dinosaur. Also presented was an exquisite skull from a tiny crocodile that could help provide vital new evidence on when the landmasses of Africa and South America split to take up their current positions on the planet's surface. The finds were described by Paul Sereno, one of the world's leading dino hunters, at the annual meeting of the American Association for the Advancement of Science in Boston. Dr Sereno, from the University of Chicago, told the meeting that science was ...

    Impact didn't lead to mass extinction 65 million years ago, geologists findThe enduringly popular theory that the Chicxulub crater holds the clue to the demise of the dinosaurs, along with some 65 percent of all species 65 million years ago, is challenged in a paper to be published in the Journal of the Geological Society on April 27, 2009. The crater, discovered in 1978 in northern Yucutan and measuring about 180 kilometers (112 miles) in diameter, records a massive extra-terrestrial impact. When spherules from the impact were found just below the Cretaceous-Tertiary (K-T) boundary, it was quickly identified as the...
  • Expert: Volcanoes in Today's India Wiped Out Dinos

    Volcanoes that erupted in India about 65 million years ago were instrumental in the extinction of dinosaurs, according to new research. For the last thirty years scientists have believed a giant meteorite that struck Mexico’s Yucatan Peninsula was responsible for the mass extinction of dinosaurs, the Daily Telegraph reported on Wednesday. But now Gerta Keller, a geologist at Princeton University, New Jersey, says fossilised traces of plants and animals dug out of low lying hills at El Penon in northeast Mexico show this event happened 300,000 years after the dinosaurs disappeared. Keller suggests that the massive volcanic eruptions at the...

    Scientists have discovered a macabre death scene that took place 67 million years ago. The setting was a nest, in which a baby dinosaur had just hatched from an egg, only to face an 11-foot-long snake waiting to devour it. The moment was frozen forever when, apparently, the nest was buried in a sudden avalanche of mud or sand and everything was fossilized.

    Dinosaur Shocker By Helen Fields Neatly dressed in blue Capri pants and a sleeveless top, long hair flowing over her bare shoulders, Mary Schweitzer sits at a microscope in a dim lab, her face lit only by a glowing computer screen showing a network of thin, branching vessels. That’s right, blood vessels. From a dinosaur. “Ho-ho-ho, I am excite-e-e-e-d,” she chuckles. “I am, like, really excited.” After 68 million years in the ground, a Tyrannosaurus rex found in Montana was dug up, its leg bone was broken in pieces, and fragments were dissolved in acid in Schweitzer’s laboratory at North...
