  • Researchers find first sign that tyrannosaurs hunted in packs

    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...

    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...

    Make no mistake, Fox News is still the ratings king. But the recent May numbers show that while all the cable channels had a decline in ratings (which is normal for May), Fox News was far from spared, with some of its lowest ratings in 12 years. While Fox dominates with the top 14 shows in overall viewers, the total day average for Fox News in the key advertising demographic of the 25- to 54-year-old category was 177,000 viewers, only the second time Fox has gone below a 200,000 average since 2001. Another key factor coming from May ratings is...

    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.

    A 'Jurassic Park' in China was once home to dinosaurs that lived among early mammals, amphibians and other strange creatures 160 million years ago. 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...

    Dark Days Doomed Dinosaurs, Say Purdue Scientists WEST LAFAYETTE, Ind. ? Though the catastrophe that destroyed the dinosaurs' world may have begun with blazing fire, it probably ended with icy darkness, according to a Purdue University research group. By analyzing fossil records, a team of scientists including Purdue's Matthew Huber has found evidence that the Earth underwent a sudden cooling 65 million years ago that may have taken millennia to abate completely. The fossil rock samples, taken from a well-known archaeological site in Tunisia, show that tiny, cold-loving ocean organisms called dinoflagellates and benthic formanifera appeared suddenly in an ancient...

    The dinosaurs were wiped out 65 million years ago by at least two meteorite impacts, rather than a single strike, a new study suggests.Previously, scientists had identified a huge impact crater in the Gulf of Mexico as the event that spelled doom for the dinosaurs. Now evidence for a second impact in the Ukraine has been uncovered. This raises the possibility that the Earth may have been bombarded by a whole shower of meteorites. The new findings are published in the journal Geology by a team lead by Professor David Jolley of Aberdeen University. When first proposed in 1980, the...

    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...

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...

The research, some of it dating to the 1990s, analyzed skeletons of different ages to estimate how quickly dinosaurs grew. For example, a 2001 paper, published in the journal Nature, estimates that the giant dinosaur Apatosaurus had a growth spurt of 12,000 pounds in a year. The papers, particularly a 2004 paper in Nature on the growth of Tyrannosaurus Rex, were influential in offering an explanation for why...

    The controversial discovery of 68 million-year-old soft tissue from the bones of a Tyrannosaurus rex finally has a physical explanation. According to newly published research, iron in the dinosaur's body preserved the tissue before it could decay. The research, headed by Mary Schweitzer, a molecular paleontologist at North Carolina State University, explains how proteins — and possibly even DNA — can survive for millennia. Schweitzer and her colleagues first raised this question in 2005, when they found the seemingly impossible: soft tissue preserved inside the leg of an adolescent T. rex unearthed in Montana.

    Giant reptiles that ruled dinosaur-era seas might have been warm-blooded, a new study says. Researchers found that ancient ocean predators possibly regulated their body temperatures, which allowed for aggressive hunting, deep diving, and fast swimming over long distances. (See "Giant 'Sea Monster' Fossil Discovered in Arctic.") "These marine reptiles were able to maintain a high body temperature independently of the water temperature where they lived, from tropical to cold-temperate oceanic domains," said study co-author Christophe Lécuyer, a paleontologist at Université Claude Bernand Lyon 1 in France. The prehistoric reptiles may have had body temperatures as high as 95 to 102...

    Caught in the act of evolution, the odd-looking, feathered dinosaur was becoming more vegetarian, moving away from its meat-eating ancestors. It had the built-for-speed legs of meat-eaters, but was developing the bigger belly of plant-eaters. It had already lost the serrated teeth needed for tearing flesh. Those were replaced with the smaller, duller vegetarian variety.

The largest footprint, measuring 28 inches across, was believed to have been left by a sauropod, a plant-eating dinosaur with a long neck and tail, small head and measuring as long as 66 feet. The other print likely was left by a smaller ankylosaur, a four-legged, thickly armored plant eater, the museum said. It was the first...

    New Haven, Conn.—It turns out that the undisputed king of the dinosaurs, Tyrannosaurus rex, didn't just eat other dinosaurs but also each other. Paleontologists from the United States and Canada have found bite marks on the giants' bones that were made by other T. rex, according to a new study published online Oct. 15 in the journal PLoS ONE. While searching through dinosaur fossil collections for another study on dinosaur bones with mammal tooth marks, Yale researcher Nick Longrich discovered a bone with especially large gouges in them. Given the age and location of the fossil, the marks had to...

    Pristine Skeletons Shed Light on Early Dinosaur Evolution A reconstruction of the newly discovered Triassic, carnivorous dinosaur, Tawa hallae. Courtesy of Jorge Gonzalez When Darwin's finches diverged from their common ancestor, the isolation of their island home allowed many species to arise from one. When their dinosaur ancestors emerged in the Triassic, the island home was the unified landmass Pangea, and the evolution was far more complicated. In the December 11, 2009, issue of Science, a team of paleontologists introduced the Triassic dinosaur Tawa hallae, an animal that may answer longstanding questions about the earliest years of dinosaur evolution. The...

    On Monday, March 21, 2011 the Royal Tyrrell Museum of Palaeontology in Drumheller, Alberta received word that the remains of either a plesiosaur or an ichthyosaur had been discovered in the Milllennium Mine operated by the petroleum company Suncor Inc. This mine is located about 30 km north of the town of Fort McMurray (population ~50,000) in northeastern Alberta (about 800km north of Drumheller), and is one of the places where bitumen rich sand is mined and refined into various petroleum products. On Wednesday, March 23, 2011 myself and technician Darren Tanke flew up to Fort McMurray expecting to see...

The carnivores that evolved alongside dinosaurs hunted with quick, opportunistic strikes... marine mega meat-eaters ripped into prey with massive, serrated teeth some 171 to 136 million years ago to satisfy a diet of at least 70 percent flesh. What's more, metriorhynchids, the extinct relatives of today's crocodiles, had a killing skill that T. Rex lacked: The death roll. The creatures would sink their teeth into prey and then spin their bodies in the water to tear out large chunks of...

    Tyrannosaurus rex was far from a plodding Cretaceous era scavenger whose long tail only served to counterbalance the up-front weight of its freakishly big headTyrannosaurus rex was far from a plodding Cretaceous era scavenger whose long tail only served to counterbalance the up-front weight of its freakishly big head. T. rex's athleticism (and its rear end) has been given a makeover by University of Alberta graduate student Scott Persons. His extensive research shows that powerful tail muscles made the giant carnivore one of the fastest moving hunters of its time. As Persons says, "contrary to earlier theories, T. rex had...
  • Pterosaur reptile used "pole vault" trick for take-off

    A new study claims that the ancient winged reptiles known as pterosaurs used a "pole-vaulting" action to take to the air.They say the creatures took off using all four of their limbs. The reptiles vaulted over their wings, pushing off first with their hind limbs and then thrusting themselves upwards with their powerful arm muscles - not dissimilar to some modern bats. The research is published in the open-access journal Plos One. Pterosaurs lived at the same time as the dinosaurs, but belonged to a different group of reptiles. They existed from the Triassic Period until the end of the...

    > The pterosaur's wingspan and size have spawned comparisons to dragons. But recently some scientists wondered whether the creature was too big to fly. A pair of papers recently asserted that the biggest pterosaurs may have been too heavy to get off the ground. That seemed implausible to Habib. After all, the biggest birds often have the longest flight range. And Quetzalcoatlus, with its 35-foot wingspan, certainly fits the bill for gigantic. So Habib teamed up with Mark Witton, a British paleontologist, to plug in factors like wingspan, weight and aerodynamics into a computer model. The results, which they presented...

    Crocodiles can no longer be referred to as "living fossils", according to scientists.Members of the crocodilian family have previously been thought to have changed little since prehistoric times. However, new fossil analyses suggests that modern crocodilians actually evolved from a very diverse group. Recently discovered ancient ancestors include small cat-like specimens, giant "supercrocs" and a pug-nosed vegetarian species. Body structureModern crocodilians are adapted to aquatic environments with long snouts, strong tails and powerful jaws. Yet contrary to popular belief, scientists now suggest that the basic body structure of crocodiles, alligators and ghariels evolved from a diverse group of prehistoric reptiles...

    By reconstructing the brains of extinct birds, researchers could shed light on when birds evolved into creatures of flight. Overwhelming evidence suggests birds evolved from dinosaurs some 150 million years ago, but one of the missing pieces to the evolutionary puzzle is how such birds took to the air. Scientists in Scotland are focusing on changes in the size of a part of the rear of the brain. This part of the cerebellum, known as the flocculus, is responsible for integrating visual and balance signals during flight, allowing birds to judge the position of other objects in midflight.

    Brontomerus mcintoshi is a newly discovered dinosaur from the Early Cretaceous of North America. The name Brontomerus means "Thunder thighs" -- a name chosen because the peculiar shape of the hip bone shows that it would have had enormously powerful thigh muscles in life. (PhysOrg.com) -- A new dinosaur named Brontomerus mcintoshi, or "thunder-thighs" after its enormously powerful thigh muscles, has been discovered in Utah, USA. The new species is described in a paper recently published in the journal Acta Palaeontologica Polonica by an international team of scientists from the U.K. and the U.S. A member of the long-necked sauropod...

    LONDON – A new dinosaur named Brontomerus mcintoshi, or "thunder-thighs" after its enormously powerful thigh muscles, has been discovered in Utah, USA. The new species is described in a paper recently published in the journal Acta Palaeontologica Polonica by an international team of scientists from the U.K. and the U.S. A member of the long-necked sauropod group of dinosaurs which includes Diplodocus and Brachiosaurus, Brontomerus may have used its powerful thighs as a weapon to kick predators, or to help travel over rough, hilly terrain. Brontomerus lived about 110 million years ago, during the Early Cretaceous Period, and probably had...
