A new species of tyrannosaur — the oldest ever found in Canada — has been discovered in Alberta. Thanatotheristes degrootorum was as long as two cars lined up bumper to bumper and would have towered over an adult human. It stood about 2.4 metres tall at the hips, said Jared Voris, a University of Calgary PhD candidate who led the research identifying it as a new species.

Samples caught in Burmese amber provide clues to the evolution of the parasites and their hosts

A young paleontologist may have discovered a record of the most significant event in the history of life on Earth.

100-million-year-old insects that fed on feathers are the oldest licelike fossils known

The fossils of a previously unknown titanosaur have been found in Ecuador. The medium to small-sized dinosaur lived 85 million years ago, during the Upper Cretaceous period. Its remains were discovered in the southern end of the country in the Loja province. It is the first time dinosaur fossils have been identified in Ecuador and the northernmost example of its sauropod subfamily found to date.

The pterosaur fossil is most closely associated with species from the other side of the world, suggesting these creatures could circumnavigate the globe.

Australian researchers have found a new species of pterosaur in outback Queensland.

Geology is a big science. The Earth is a large enough place today, but when you stretch the fourth dimension back across many millions of years, the largeness can get out of hand. Because we lose a lot of detail to the ravages of time, it's very difficult for geology to get small again—to tell us about what happened in individual locations or over short periods of time.

Tyrannosaurus rex, one of the largest meat-eating dinosaurs on the planet, had an air conditioner in its head, suggest scientists who are challenging over a century of previous beliefs.

A new species of dinosaur has been discovered, after being misidentified and kept in a museum collection for several decades.

A Triceratops fossil was uncovered by a UC Merced student and an experienced excavator in the Badlands of North Dakota.

A college student made the discovery of a lifetime on a recent paleontology dig when he unearthed a partial Triceratops skull.

Share A team of Argentine paleontologists unearthed a giant reptile in Antarctica. Looking like the famous Loch Ness monster, this huge Elasmosaurid found in Antarctica is the largest one of its species ever found so far. The Argentine Antarctic Institute conducted the research, and the paleontologist José O’Gorman of the Museum of La Plata...

A number of tiny, bat-winged dinosaurs flew the Jurassic skies, according to the strongest evidence yet for such creatures—a well-preserved fossil of a starling-size fluffball that may have looked a little like a flying squirrel. The find, recovered near a farming village in northeastern China, suggests dinosaurs were experimenting with several methods of flight during this period, but many were an evolutionary dead end.

An asteroid slammed down and did away with all the dinosaurs, paving the way for such developments as the human race, capitalism, and posting on the internet: it’s the story we all know and love. Yet if things had shaken out differently—if the asteroid had stayed in its place, and the dinosaurs allowed to proceed with their business—what would things have looked like?

Sixty-five million years ago, an asteroid is believed to have crashed into Earth. The impact wiped out huge numbers of species, including almost all of the dinosaurs. One group of dinosaurs managed to survive the disaster. Today, we know them as birds.

Sixty-six million years ago, a giant meteor slammed into Earth off the coast of modern-day Mexico. Firestorms incinerated the landscape for miles around. Even creatures thousands of miles away were doomed on that fateful day, if not by fire and brimstone, then by mega-earthquakes and waves of unimaginable size.

Scientists in the US say they have discovered the fossilized remains of a mass of creatures that died minutes after a huge asteroid slammed into the Earth 66 million years ago, sealing the fate of the dinosaurs. In a paper to be published Monday, a team of paleontologists headquartered at the University of Kansas say they found a "mother lode of exquisitely preserved animal and fish fossils" in what is now North Dakota.

If, on a certain evening about sixty-­six million years ago, you had stood somewhere in North America and looked up at the sky, you would have soon made out what appeared to be a star. If you watched for an hour or two, the star would have seemed to grow in brightness, although it barely moved. That’s because it was not a star but an asteroid, and it was headed directly for Earth at about forty-five thousand miles an hour.

New research captures a fossilized snapshot of the day nearly 66 million years ago when an asteroid smacked Earth and nearly all life on Earth went extinct, including the dinosaurs.
