ScienceDaily (Apr. 22, 2009) — During the summers of 2006 and 2007, an international team of researchers from China and the United States excavated a treasure trove of dinosaur skeletons from Early Cretaceous rocks in the southern part of the Gobi Desert near the ancient Silk Road city of Jiayuguan, Gansu Province, China. Two of their discoveries represent new species of theropod dinosaurs. The new species are described in the Proceedings of the Royal Society B. The papers will appear in print later this year in a special volume entitled "Recent advances in Chinese palaeontology."

Protein analysis confirms modern birds descended from huge predatory dinosaur, study finds. In the first analysis of proteins extracted from dinosaur bones, scientists say they have established more firmly than ever that the closest living relatives of the mighty predator Tyrannosaurus rex are modern birds. The research, being published today in...

A new family tree based on protein sequences recovered from dinosaur fossils firms up the dinosaur's avian lineage. "Palaeontologists have known this overall connection. We have now confirmed it with molecular data," says John Asara, a biochemist at Beth Israel Deaconess Medical Center in Boston, who led the study....

WASHINGTON - One of the most complete dinosaur mummies ever found is revealing secrets locked away for millions of years, bringing researchers as close as they will ever get to touching a live dino. The fossilized duckbilled hadrosaur is so well preserved that scientists have been able to calculate its muscle mass and learn that it was more muscular than thought, probably giving it the ability to outrun predators such as T. rex. While they call it a mummy, the dinosaur is not really preserved like King Tut was. The dinosaur body has been fossilized into stone. Unlike the collections...

LONDON (AFP) - A Britain-based palaeontologist believes he has found the world's first known Tyrannosaurus rex footprint, he told a BBC television documentary Wednesday. Phil Manning said he has high hopes the one square metre (about 11 square feet) print, from the famed Hell Creek area of the northwest US state of Montana, is from the flesh-eating giant, although 100 percent certainty is impossible. "People have been trying to find T.rex tracks for a hundred years," Manning, who specialises in Jurassic and Cretaceous period dinosaur tracks, told the BBC. "Unless you come across an animal dead in its tracks you...

A paleo-bully of sorts, Tyrannosaurus rex could chomp down on prey with the force needed to lift a semitrailer, tearing apart a victim's bones. Now researchers have discovered the dino's secret weapon: It was hard-headed. "Fused, archlike nasal bones are a unique feature of tyrannosaurids," said lead scientist Eric Snively of the University of Alberta. "This adaptation, for instance, was keeping the T. rexes from breaking their own skull while breaking the bones of their prey."

WASHINGTON - Researchers have decoded proteins from a 68 million-year-old Tyrannosaurus rex, the oldest such material ever found. The unprecedented step, once thought impossible, adds new weight to the idea that today's birds are descendants of the mighty dinosaurs. "The door just opens up to a whole avenue of research that involves anything extinct," said Matthew T. Carrano, curator of dinosaurs at the Smithsonian's National Museum of Natural History. While dinosaur bones have long been studied, "it's always been assumed that preservation does not extend to the cellular or molecular level," said Mary Higby Schweitzer of North Carolina State University....

Leaping lizards! It took an act of God to render dinosaurs extinct, but real chutzpah to lay low a beloved orange landmark that has loomed over Route 1 for 47 years. “It’s Easter Sunday. Jesus Christ rose from the dead and so will that dinosaur,” vowed Diana Fay, owner of Route 1 Miniature Golf and Batting Cages in Saugus. Despite massive hind legs fortified with concrete and steel rods, the fiberglass Tyrannosaurus rex was viciously dinosaur-tipped sometime between late Thursday night and early Friday morning. Fay’s late uncle, Nicholas Melchionna, had the reptilian reproduction built in South Boston in 1960...

Youth was easy for big predatory dinosaurs – but adulthood and old age much harder to survive, a mass graveyard of tyrannosaur fossils suggests. This first study of dinosaur population distributions shows that most juvenile tyrannosaurs survived to reach sexual maturity, but then their death rate increased sharply in adulthood. This life-pattern is similar to those of long-lived birds and mammals. *SNIP Biologists study population distributions of modern animals by counting individuals and keeping track of deaths. This is not possible for extinct creatures, and fossilised remains are also scant for many dinosaurs. But Erickson turned to the tyrannosaur family...

In the 1993 movie Jurassic Park, one human character tells another that a Tyrannosaurus rex can't see them if they don't move, even though the beast is right in front of them. Now, a scientist reports that T. rex had some of the best vision in animal history. This sensory prowess strengthens arguments for T. rex's role as predator instead of scavenger. Scientists had some evidence from measurements of T. rex skulls that the animal could see well. Recently, Kent A. Stevens of the University of Oregon in Eugene went further. He used facial models of seven types of dinosaurs...

I am curious why none of the media covers the most important aspect of the Malvo shootings. If you look at Newspapers on the dates when the shootings are underway you discover something I find quite interesting. The shootings begin to dominate the news the day before the debate on the Iraq war starts and they catch them the day after the declaration of war??? If you ask most people "do you remember the debate about starting the second Iraq war", they will all answer "yes of course". But if you followup with the question "name one point in the...

I recently received a reply to a post that stated: "This should be beneath a "freeper". Sad." So I asked.. what is it that makes a FReeper? My reply (and I will admit was tasteless) was also questioning. It stirred controversy and was removed? Why Moderators? Can you not tell me? Did it not meet with your "FReeper" mentality? According to all posted guidelines it should be listed but no, you chose to delete it. Yes.. I'm the first one IBTZ, I'm sure you'll nick me for speaking up..

THE biggest, and possibly the baddest predatory dinosaur of them all was not the fabled Tyrannosaurus rex, or even its slightly larger rival Gigantosaurus, but a long-jawed, sail-backed creature called Spinosaurus. An examination of some newly obtained fossils shows that Spinosaurus stretched an impressive 17 metres from nose to tail, dwarfing its meat-eating relatives. As well as being longer than its rivals, Spinosaurus also had stronger arms with which to catch its prey, unlike the puny-armed T. rex and its ilk. Until 10 years ago, T. rex held the mantle of the biggest predatory dinosaur. Of the 30 specimens collected...

NEW YORK - Scientists say they've found the earliest known tyrannosaur, shedding light on the lineage that produced the fearsome Tyrannosaurus rex. The discovery comes with a puzzle: Why did this beast have a strange crest on its head? Digging in the badlands of northwestern China that appeared in the movie "Crouching Tiger, Hidden Dragon," researchers found two skeletons of a creature that lived some 160 million years ago. That's more than 90 million years before T. rex came along. A two-legged meat-eater, the beast was far smaller than T. rex, measuring about 10 feet from its snout to the...

COLUMBUS, Ga. - Paleontologists have identified a new dinosaur species, an early relative of Tyrannosaurus rex that probably roamed what is now the Southeastern United States about 77 million years ago. The scientists made the identification from hundreds of fossilized fragments collected mostly in Montgomery County, Ala., and southwestern Georgia. They named the new dinosaur Appalachiosaurus montgomeriensis, which means "the Appalachian lizard from Montgomery County." The 25-foot-long creature roamed the earth 10 million years before T. rex and was smaller and more primitive, with a narrower snout. David R. Schwimmer of Columbus State University; Thomas Carr of Carthage College of...

Many argue that communism will never be possible because of "human nature". The essence of this false argument is the belief that a communist society would consist of an all-powerful central government that would tell everybody what to do--and would therefore undermine the creative initiative of individuals and the search for happiness. • This argument is based on two false assumptions: (1) It assumes that a communist society will look like the former Soviet Union, or the current China, North Korea, etc (ie: corrupt police states with a feudal-style ruling class) (2) It assumes that people will only work in...

WASHINGTON — For more than a century, the study of dinosaurs has been limited to fossilized bones. Now, researchers have recovered 70-million-year-old soft tissue, including what may be blood vessels and cells, from a Tyrannosaurus rex. If scientists can isolate proteins from the material, they may be able to learn new details of how dinosaurs lived, said lead researcher Mary Higby Schweitzer of North Carolina State University. "We're doing a lot of stuff in the lab right now that looks promising,'' she said in a telephone interview. But, she said, she does not know yet if scientists will be able...

<p>"But now a 70-million-year-old Tyrannosaurus rex discovered in Montana has apparently yielded the improbable, scientists reported yesterday: soft tissues, including blood vessels and possibly cells lining them, that "retain some of their original flexibility, elasticity and resilience."</p> <p>Moreover, an examination with a scanning electron microscope showed the dinosaur's blood vessels to be "virtually indistinguishable" from those recovered from ostrich bones. The ostrich is today's largest bird, and many paleontologists think birds are living descendants of some dinosaurs."</p>
