Paleontologist: Broken bones at Utah site show dinosaurs were trampled by own kind after deathOctober 13th, 2009 Scientist: Dinos trampled after death by own kindSALT LAKE CITY — Paleontologists say analysis of a vast collection of broken dinosaur bones unearthed in southeast Utah indicates they were trampled by other dinosaurs shortly after they died. Brigham Young University scientists have spent years analyzing more than 4,000 bones from a quarry just west of Arches National Park.
Archaeopteryx was less bird like, more like dinosOctober 9th, 2009 WASHINGTON - A new research has shown that the Archaeopteryx, which has long been considered the iconic first bird, was less bird like, and more like dinosaurs. The research, by Gregory Erickson of the Department of Biological Science at Florida State University, involved microscopic imaging of bone structure, which showed that the famously feathered fossil of the archaeopteryx grew much slower than living birds and more like non-avian dinosaurs.
Artificial bone made of wood may allow broken human bones to heal fasterAugust 17th, 2009 WASHINGTON - Italian scientists have developed a new procedure to turn blocks of wood into artificial bones, which may be implanted into large animals and eventually humans, allowing live bones to heal faster and more securely after a break than currently available metal and ceramic implants. According to a report in Discovery News, the researchers chose wood because it closely resembles the physical structure of natural bone, "which is impossible to reproduce with conventional processing technology."
"Our purpose is to convert native wood structures into bioactive, inorganic compounds destined to substitute portions of bone," said Anna Tampieri, a scientist at the Instituto Di Scienza E Techologia Dei Materiali Ceramici in Italy.
The "hobbit" evolved separate to humansJuly 31st, 2009 SYDNEY - A new research by Australian scientists has said that the bones of the "hobbit", found in Indonesia, suggest that the species is not related to homo sapiens, and evolved separate to humans. Discovered on the Indonesian island of Flores in 2003 and dubbed 'the Hobbit', the species triggered a worldwide debate about its origins.
Eating more and using less energy made dinos giganticJuly 9th, 2009 SYDNEY - A US scientist has said that some dinosaurs grew larger than today's elephants because they ate more and used less energy. According to a report in ABC Science, the study suggests two factors, energy expenditure and food intake, influence the size of animals.
Gargantuan dinos the 'couch potatoes' of prehistoric worldJuly 7th, 2009 LONDON - A new research has determined that due to their huge sizes, dinosaurs were the 'couch potatoes' of the prehistoric world. According to a report in the Telegraph, the research was done by Dr McNab from the University of Florida.
Earliest land vertebrates were more diverse than earlier believedJuly 7th, 2009 WASHINGTON - A new study of ancient fossils has determined that the earliest land vertebrates, also known as tetrapods, were more diverse than we could possibly imagine. The study was done by Jennifer Clack, a paleontologist at the University of Cambridge, who has studied the fossils of these extinct creatures for more than two decades.
High CO2 levels lead to abnormally large fish ear bonesJune 26th, 2009 WASHINGTON - Rising carbon dioxide (CO2) levels in the ocean can cause abnormally large growth in the otoliths, or ear bones, of fish, say researchers at Scripps Institution of Oceanography at UC San Diego. Considered a fundamental bodily structure in fish, otoliths serve a vital function in fish by helping them sense orientation and acceleration.
Adding carbon dioxide to oceans causes fish ear bones to grow larger, scientists findJune 25th, 2009 Surprise: Fish in acidic waters grow bigger earsWASHINGTON — Listen up! Carbon dioxide being absorbed by the oceans is having a puzzling effect on fish — their ears get bigger. Now, that doesn't mean you're going to reel in the Mr.
6,000-year-old ancient tombs discovered in BritainJune 9th, 2009 LONDON - A prehistoric complex including two 6,000-year-old tombs representing some of the earliest monuments built in Britain has been discovered by a team led by a Kingston University archaeologist. According to a report in Alpha Galileo, Dr Helen Wickstead and her colleagues were stunned and delighted to find the previously undiscovered Neolithic tombs, also known as long barrows at a site at Damerham, Hampshire.
Giant dinos may have held their head higher for much of the timeMay 27th, 2009 LONDON - New findings have suggested that 150 million years ago, giant dinosaurs known as Sauropods, may have held its head higher for much of the time. According to a report by BBC News, by studying the skeletons of living vertebrates, Mike Taylor, from the University of Portsmouth, and his team, reshaped the dinosaur's resting pose.
Dinos may have survived extinction for half a mln yrs in 'lost world' in AmericaApril 28th, 2009 WASHINGTON - New scientific evidence suggests that dinosaur bones from the Ojo Alamo Sandstone in the San Juan Basin, USA, date from after the mass extinction event, and that dinos may have survived in a remote area of what is now New Mexico and Colorado for up to half a million years, in a scenario resembling that of the fictional 'Lost World'. This controversial new research, is based on detailed chemical investigations of the dinosaur bones, and evidence for the age of the rocks in which they are found.
Tooth evidence shows dinos once lived in the ArcticApril 27th, 2009 WASHINGTON - Scientists have discovered a dinosaur tooth along what's now the Kakanaut River of northeastern Russia, a find that shows dinos once lived above the Arctic Circle. Scientists say the dinosaurs became extinct 65 million years ago when a big meteor crash set off volcanoes galore, with dust and smoke filling up the air.
Rare snapshot of young dinos who roamed and died together 90 mln yrs agoMarch 17th, 2009 WASHINGTON - A team of Chinese and American paleontologists has analyzed the skeletons of a herd of young birdlike dinosaurs that were found in a mud trap in the Gobi Desert in western Inner Mongolia, thus providing a rare snapshot of the social behavior of these dinos who roamed and died together 90 million years ago. Paul Sereno, professor at the University of Chicago, Tan Lin, from the Department of Land and Resources of Inner Mongolia, and Zhao Xijin, professor in the Chinese Academy of Sciences, led the expedition that found the fossils in 2001.
Young dinos lived and died togetherMarch 16th, 2009 WASHINGTON - A herd of young birdlike dinosaurs met their death on the muddy margins of a lake some 90 million years ago, according to a team of Chinese and American palaeontologists. Composed entirely of juveniles of a single species of ornithomimid dinosaur (Sinornithomimus dongi), the herd suggests that immature individuals were left to fend for themselves when adults were preoccupied with nesting or brooding.
