Paleontologists doubt 'dinosaur dance floor'
A group of paleontologists visited the northern Arizona wilderness site nicknamed a "dinosaur dance floor" and concluded there were no dinosaur tracks there, only a dense collection of unusual potholes eroded in the sandstone.   view more (2008-11-10)

Study of polar dinosaur migration questions whether dinosaurs were truly the first great migrators
Contrary to popular belief, polar dinosaurs may not have traveled nearly as far as originally thought when making their bi-annual migration.   view more (2008-10-22)

Brain structure provides key to unraveling function of bizarre dinosaur crests
Paleontologists have long debated the function of the strange, bony crests on the heads of the duck-billed dinosaurs known as lambeosaurs. The structures contain incredibly long, convoluted nasal passages that loop up over the tops of their skulls.   view more (2008-10-16)

Gene expression in alligators suggests birds have 'thumbs'
The latest breakthrough in a 120 year-old debate on the evolution of the bird wing was published in the open-access journal PLoS ONE.   view more (2008-10-06)

Canada's shores saved animals from devastating climate change
The shorelines of ancient Alberta, British Columbia and the Canadian Arctic were an important refuge for some of the world's earliest animals, most of which were wiped out by a mysterious global extinction event some 252 million years ago.   view more (2008-10-01)

Meat-eating dinosaur from Argentina had bird-like breathing system
The remains of a 30-foot-long predatory dinosaur discovered along the banks of Argentina's Rio Colorado is helping to unravel how birds evolved their unusual breathing system.   view more (2008-09-30)

America's smallest dinosaur uncovered
An unusual breed of dinosaur that was the size of a chicken, ran on two legs and scoured the ancient forest floor for termites is the smallest dinosaur species found in North America, according to a University of Calgary researcher who analyzed bones found during the excavation of an ancient bone... view more (2008-09-24)

My, what big teeth you had! Extinct species had large teeth on roof of mouth
When the world's land was congealed in one supercontinent 240 million years ago, Antarctica wasn't the forbiddingly icy place it is now. But paleontologists have found a previously unknown amphibious predator species that probably still made it less than hospitable.   view more (2008-09-12)

Ancient mother spawns new insight on reptile reproduction
A 75-million-year-old fossil of a pregnant turtle and a nest of fossilized eggs that were discovered in the badlands of southeastern Alberta by scientists and staff from the University of Calgary and the Royal Tyrrell Museum of Palaeontology are yielding new ideas on the evolution of egg-laying and... view more (2008-08-28)

Duck-billed dinosaurs outgrew predators to survive
With long limbs and a soft body, the duck-billed hadrosaur had few defenses against predators such as tyrannosaurs. But new research on the bones of this plant-eating dinosaur suggests that it had at least one advantage: It grew to adulthood much faster than its predators, giving it superiority in... view more (2008-08-06)

Mysterious mountain dino may be a new species
A partial dinosaur skeleton unearthed in 1971 from a remote British Columbia site is the first ever found in Canadian mountains and may represent a new species, according to a recent examination by a University of Alberta researcher.   view more (2008-06-13)

For the paper trail of life on Mars or other planets, find cellulose
Looking for evidence of life on Mars or other planets? Finding cellulose microfibers would be the next best thing to a close encounter, according to new research from the University of North Carolina at Chapel Hill.   view more (2008-03-31)

Tuatara, the fastest evolving animal
In a study of New Zealand's "living dinosaur" the tuatara, evolutionary biologist, and ancient DNA expert, Professor David Lambert and his team from the Allan Wilson Centre for Molecular Ecology and Evolution recovered DNA sequences from the bones of ancient tuatara, which are up to 8000... view more (2008-03-24)

New dinosaur from Mexico offers insights into ancient life on West America
A new species of dinosaur unearthed in Mexico is giving scientists fresh insights into the ancient history of western North America, according to an international research team led by scientists from the Utah Museum of Natural History at the University of Utah.   view more (2008-02-13)

Mongolian paleontologists with a dream come to MSU
Jack Horner has flown to Mongolia the past three summers to search for dinosaur bones. Now three members of his field crew have joined him at Montana State University to start developing a new generation of Mongolian paleontologists.   view more (2008-01-16)

Unusual fish-eating dinosaur had crocodile-like skull
An unusual dinosaur has been shown to have a skull that functioned like a fish-eating crocodile, despite looking like a dinosaur. It also possessed two huge hand claws, perhaps used as grappling hooks to lift fish from the water.   view more (2008-01-14)

Insect attack may have finished off dinosaurs
Asteroid impacts or massive volcanic flows might have occurred around the time dinosaurs became extinct, but a new book argues that the mightiest creatures the world has ever known may have been brought down by a tiny, much less dramatic force - biting, disease-carrying insects.   view more (2008-01-03)

Student identifies enormous new dinosaur
The remains of one of the largest meat-eating dinosaurs ever found have recently been recognized as representing a new species by a student working at the University of Bristol.   view more (2007-12-12)

Massive dinosaur discovered in Antarctica sheds light on life, distribution of sauropodomorphs
A new genus and species of dinosaur from the Early Jurassic has been discovered in Antarctica. The massive plant-eating primitive sauropodomorph is called Glacialisaurus hammeri and lived about 190 million years ago.   view more (2007-12-11)

Dinosaur from Sahara ate like a 'mesozoic cow'
A 110 million-year-old dinosaur that had a mouth that worked like a vacuum cleaner, hundreds of tiny teeth and nearly translucent skull bones will be unveiled Thursday, Nov. 15, at the National Geographic Society.   view more (2007-11-16)

Why dinosaurs had fowl breath
Scientists have discovered how dinosaurs used to breathe in what provides clues to how they evolved and how they might have lived.   view more (2007-11-07)

Emory paleontologist reports discovery of carnivorous dinosaur tracks in Australia
The first fossil tracks belonging to large, carnivorous dinosaurs have been discovered in Victoria, Australia, by paleontologists from Emory University, Monash University and the Museum of Victoria (both in Melbourne).   view more (2007-10-22)

Toothy dinosaur newest to come out of southern Utah
The newest dinosaur species to emerge from Grand Staircase-Escalante National Monument had some serious bite, according to researchers from the Utah Museum of Natural History at the University of Utah.   view more (2007-10-04)

Velociraptor had feathers
A new look at some old bones have shown that velociraptor, the dinosaur made famous in the movie Jurassic Park, had feathers. A paper describing the discovery, made by paleontologists at the American Museum of Natural History and the Field Museum of Natural History, appears in the Sept. 21 issue of... view more (2007-09-21)

Height or flight?
Paleontologists have long theorized that miniaturization was one of the last stages in the long series of changes required in order for dinosaurs to make the evolutionary "leap" to take flight and so become what we call birds.   view more (2007-09-07)
