Sixty six million years ago, a massive asteroid impact wiped out about three quarters of all life on Earth, including every ...

German scientists found evidence that the space rock came from the outer limits of our solar system, well beyond Jupiter, during its early development.

However, the fossil really stands out because, in a rare stroke of luck for paleontologists, its bony vocal organs were ...

Scientists in China report the discovery of a new dinosaur species that might have sounded like a bird. Researchers ...

Despite what the movies tell us, dinosaurs probably didn't roar at their prey. It's more likely that they chirped like birds, ...

The fossil skeleton of a newly discovered dinosaur species was found in a pose suggesting it slept like modern birds. This sleeping behavior may have been more common than expected among non-avian ...

If you could travel back in time to the Cretaceous period, between 145 million and 66 million years ago, you would have ...

“We hold those two facts in our heads, both that the non-avian dinosaurs went extinct and that we have birds today. And that there’s this divide between non-avian dinosaurs and birds.

Roughly 75% of all species vanished, including every non-avian dinosaur. It was caused by a giant asteroid, possibly 9 to 14.5 kilometers wide, that slammed into what is now the Yucatán Peninsula ...

Considering the neuroanatomical similarities between these birds and their non-avian forebearers, it is plausible that the skill originated even earlier in the dinosaur lineage.

This contrasts starkly with the evolutionary tree of dinosaurs. “Non-avian dinosaurs lost so many species, they lost entire lineages, which we don’t see in angiosperms,” Dr. Thompson said.

This “drastic miniaturization” may have led the non-avian dinosaurs to adopt the same thermoregulatory strategy used by their avian cousins, Kobu said.
