Using robotic and animal models, researchers have shown that some dinosaurs were already flapping their rudimentary wings as a side effect of running, prior to evolving the ability to fly. The finding ...

RALEIGH, N.C. — A rethink of four-winged dinosaurs suggests that the much-debated hind wings stayed tucked under the body until deployed in the air for tight turns to dodge branches or chase prey.

An early winged dinosaur couldn’t fly, but it could run. Now, with assists from a robotic dino and young ostriches wearing artificial wings, a study suggests that the dinosaur’s running gait caused ...

A new raptorial dinosaur fossil with exceptionally long feathers has provided exciting insights into dinosaur flight. A new article asserts that the fossil has a long feathered tail that scientists ...

Archaeopteryx had a wing that was different from that of modern birds, and, as seen here, might have been a glider more than a powered flyer. Art by Carl Buell, courtesy of Nicholas Longrich How did ...

A non-avian dinosaur with exceptionally long feathers has been discovered in China. Called Changyuraptor yangi, the 125 million-year-old flying raptor measured nearly four feet long, making it the ...

A bird that lived 147 million years ago had a brain similar to a modern eagle or parrot and all the equipment for flight, scientists said Wednesday. Archaeopteryx is the most ancient bird known. It ...

A study finally gives the late-Jurassic dinosaur Archaeopteryx its wings, determining the beast was capable of powered flight. For decades, paleontologists debated whether Archaeopteryx used its wings ...

A small, feathered dinosaur that probably sported bat-like wing membranes might have been able to glide or fly short distances. The fossilized remains of the creature, unearthed in eastern China and ...

WASHINGTON, May 8 (Reuters) - A fossil unearthed in northeastern China of a feathered dinosaur a bit bigger than a blue jay that possessed bat-like wings represents a remarkable but short-lived detour ...
