Duck-billed dinosaur crests not linked to sense of smell
After decades of debate, a U of T researcher has finally determined that duck-billed dinosaurs' massive but hollow crests had nothing to do with what many scientists suspected - the sense of smell. view more (2006-01-25)

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 years old. view more (2008-03-24)
Smallest Triceratops skull described
With its big, hockey puck-sized eyes, shortened face and nubby horns, it was probably as cute as a button-at least to its mother, a three-horned dinosaur called Triceratops that could weigh as much as 10 tons and had one of the largest skulls of any land animal on the planet. view more (2006-03-07)
The world's deepest dinosaur finding-2256 metres below the seabed
The somewhat rough uncovering of Norway's first dinosaur happened in the North Sea, at an entire 2256 metres below the seabed. It had been there for nearly 200 million years, ever since the time the North Sea wasn't a sea at all, but an enormous alluvial plane. view more (2006-04-25)
Ancient birds flew on all-fours

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 bed near Red Deer, Alberta. view more (2008-09-24)
Revueltosaurus skeleton unearthed at Petrified Forest upsets dinosaur tale
The fossilized skeleton of a small crocodile relative excavated last year at Petrified Forest National Park in Arizona throws a wrench into theories of how and where the dinosaurs arose more than 210 million years ago at the end of the Triassic Period. view more (2005-06-24)
Earliest embryos ever discovered provide clues to dinosaur evolution, parenting
The embryos of a long-necked, herbivorous dinosaur are the earliest ever recorded for any terrestrial vertebrate and point to how primitive dinosaurs evolved into the largest animals ever to walk on earth. view more (2005-07-29)
Dinosaur Fossil Bone Leads to Gender, Age Determinations
Paleontologists at North Carolina State University have determined that a 68 million year-old Tyrannosaurus Rex fossil from Montana is that of a young female, and that she was producing eggs when she died. view more (2005-06-02)
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)
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 the journal Science. view more (2007-09-21)
Skull study sheds light on dinosaur diversity
With their long necks and tails, sauropod dinosaurs-famous as the Sinclair gasoline logo and Fred Flintstone's gravel pit tractor-are easy to recognize, in part because they all seem to look alike. view more (2005-09-16)
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)
MSU, Mongolian paleontologists find 67 dinosaurs in one week
One recent week in the Gobi Desert produced 67 dinosaur skeletons for a team of paleontologists from Montana and Mongolia who want to flesh out the developmental biology of dinosaurs. view more (2006-09-15)

Amateur Finds Prehistoric Lizard
When amateur fossil finder Van Turner discovered a small vertebra at a construction site near Dallas 16 years ago, he knew the creature was unlike anything in the fossil record. view more (2005-11-17)
Math and fossils resolve a debate on dinosaur metabolism
Of the many mysteries surrounding the life history of dinosaurs, one of the more enduring is how such gigantic organisms—some reaching 42 feet tall and weighing 90 tons—regulated their body temperature. view more (2006-07-11)
Soft tissue taken from Tyrannosaurus rex fossil yields original protein
What happens when a 68 million-year-old Tyrannosaurus Rex meets 21st century medical science? A North Carolina State University researcher and her colleagues at Harvard Medical School and Beth Israel Deaconess Medical Center found out when they confirmed the existence of protein in soft tissue recovered from the bone of a 68 million-year-old T.... view more...
