TORONTO (Reuters) - The Canadian oil sands, a vast expanse of tar and sand being mined for crude oil, yielded treasure of another kind this week when an oil company worker unearthed a 110-million-year-old dinosaur fossil that wasn't supposed to be there.

Fossils of a recently discovered dinosaur species in Argentina is a "missing link" in the evolution of the long-necked giants that roamed the earth millions of years ago, paleontologists said.

A new dinosaur named "Thunder Thighs" has been identified by British and US scientists who said its huge, muscular legs would have given it a fierce kick.

ANCHORAGE, Alaska (Reuters) - Fossilized tracks from two newly discovered prehistoric birds have been found in Alaska's Denali National Park, according to findings released by an expert in Arctic paleontology.

Palaeontologists fought back on Wednesday in a spirited debate over the Tyrannosaurus rex, saying revisionists who branded the great dinosaur a shameless scavenger have got it all wrong.

Researchers in China have unearthed a miniature single-clawed dinosaur that was likely an early relative of the ferocious T. Rex and is the only such creature known to have just one finger.

Her life came to a crashing end, but the fossil left by a flying reptile nicknamed Mrs T has shed light on what female pterosaurs looked like when they soared above Earth millions of years ago.

BUENOS AIRES (Reuters) - A small predator that hunted in South America 230 million years ago represents one of the earliest-known dinosaurs and foreshadowed later meat-eating beasts like Tyrannosaurus rex, according to scientists from Argentina and the United States.

The fossil of a never-before seen species of dinosaur that could have been among the first to roam the planet 230 million years ago has been unearthed in Argentina, a study said Thursday.

Bird-like dinosaurs long believed to be carnivorous predators were in fact plant lovers, with the notable exception of dedicated hunters such as T. rex, US paleontologists said Monday.

The fossil of a new type of small horned dinosaur has been discovered in South Korea, the first of its kind in an area where such finds are rare, scientists said on Tuesday.

Free from competition from massive reptiles, mammals ate a lot and used their new size to stay warm and fend off predators, according to a global study released Thursday on how mammals grew after the extinction of the dinosaurs.

Exhibit of dinosaur fossils from China makes world premiere at Ohio museum. A fossilized nest of eggs laid by an unknown species of dinosaur is part of an exhibit that makes its world premiere Friday at an Ohio museum.

Pterosaurs, the largest creatures ever to take to the skies, were adept fliers in a balmy breeze but would have crashed in stormy weather, according to a study published Wednesday.

Scientist: Full skeleton found in China of ancestor of sauropod dinosaurs. Scientists say they've found the first complete skeleton of a dinosaur that is an ancestor to the sauropod, the largest creature ever to walk the planet. The 30-foot-long skeleton, complete with skull, may help reveal the story of how the 120-foot-long, giant-necked sauropods evolved and became solely plant eaters.
