Paleontologist: Broken bones at Utah site show dinosaurs were trampled by own kind after death

October 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.

October 7th, 2009 Big dino prints found in Jurassic park in FrancePARIS — Now that's one big foot. Paleontologists in eastern France have reported the discovery of some of the largest dinosaur footprints ever documented, measuring about 1.4 meters to 1.5 meters (4.6 feet to 4.9 feet) in diameter.

October 7th, 2009 WASHINGTON - Trackway analysis by researchers at the University of Michigan, Argentina's Universidad de Buenos Aires, and the Iziko South African Museum in Cape Town, South Africa has shown how early dinosaurs made on-the-fly adjustments to their movements to cope with slippery and sloping terrain. ANN ARBOR, Mich.---A new investigation of a fossilized tracksite in southern Africa shows Differences in how early dinosaurs made these adjustments provide insight into the later evolution of the group.

August 21st, 2009 WASHINGTON - Paleontologists working in southern Utah, US, have unearthed a Dolichorhynchops plesiosaur-a gigantic Dinosaur Era marine reptile-with 289 stones in its gut. "At the moment, it seems as though the stones served some sort of digestive purpose, helping to grind up bits of shell or bony material within the gut," Rebecca Schmeisser, a University of Nebraska paleontologist, told Discovery News.

July 24th, 2009 Ancient mammal tracks found at national monumentSALT LAKE CITY — Hundreds of tiny footprints left by mammals some 190 million years ago have been found on a canyon wall in a remote part of Dinosaur National Monument, park officials said Thursday. The tracks are a rare find, mostly because they were left at a time when the area was a hostile, vast Sahara-like desert where towering sand dunes seldom preserved signs of animal life.

July 3rd, 2009 Australian dinosaur that lived 98M years ago foundCANBERRA, Australia — Scientists have confirmed for the first time that Australia was once home to a dinosaur that was big, fast and terrifying, and they've named it like something from an Arnold Schwarzenegger movie.

June 25th, 2009 Montana dino hunter gets probation in theft caseGREAT FALLS, Mont. — Renowned dinosaur hunter Nathan Murphy was sentenced Wednesday to four months in a halfway house and three years probation after pleading guilty to stealing fossils.

June 23rd, 2009 LONDON - Dinosaurs, the largest animals ever to have walked the face of the earth may not have been as big as previously thought, according to the latest research. Scientists have found that the original statistical model used to calculate dinosaur mass is flawed, which means that dinosaurs have been possibly oversized.

June 21st, 2009 LONDON - Tyrannosaurus rex, the best-known predatory species, may have been far more lithe than previously thought, researchers have discovered. In a new study, boffins have claimed that dinosaurs may have been much lighter and sleeker than earlier believed because of potential flaws in the equations used to calculate their weight, reports The Times.

June 18th, 2009 WASHINGTON - In a new study, scientists have found the fossilized hand of a long-necked, ostrich-like dinosaur in China, which may help solve the mystery of how bird wings evolved from dinosaur limbs. According to a report in National geographic News, the ancient digits belonged to a 159-million-year-old theropod dinosaur dubbed Limusaurus inextricabilis.

June 13th, 2009 WASHINGTON - A new study has suggested that humungous dinosaurs may have offset the consequences of being so large by quick healing of their bones. The study used high-resolution computed tomography (CT) imaging to guide sampling of bone lesions in the vertebrae of a hadrosaur ("duck-billed") dinosaur for histological and isotopic analysis.

June 5th, 2009 Scientists find more dinosaur bones at Utah quarrySALT LAKE CITY — Scientists at one of Utah's major new dinosaur quarries have found 60 to 70 new bones this spring, including what appears to be a 20-foot-long neck bone discovered this week. The latest finds are fresh evidence that the site near Hanksville could be a large and important source of bones in the coming years.

June 2nd, 2009 Montana man gets 60 days for dinosaur bones theftBILLINGS, Mont. — A commercial fossil hunter, whose discovery of the world's best-preserved dinosaur brought scientific acclaim, will serve 60 days in jail for stealing raptor bones from private land.

April 29th, 2009 Dino-mite: Utah quarry gets explosive treatmentSALT LAKE CITY — Sometimes the delicate tools of dinosaur diggers just don't cut it. Thwarted since 2007 by layers of rock-hard sandstone, researchers at one of Dinosaur National Monument's most important quarries turned to something more potent than brushes and hammers: explosives.
