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.

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 ...

The invention of the biplane marked the beginning of manned flight, and now some researchers believe that the wing-on-top-of-wing design was present in an early flying animal as well. A new ...

Birds can fly—at least, most of them can. Flightless birds like penguins and ostriches have evolved lifestyles that don't require flight. However, there's a lot that scientists don't know about how ...

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 ...

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 ...

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 ...

Flashy feathers get all the attention in the evolution of dinosaur flight, but a more complex internal adaptation provided the aerodynamics necessary for lizards to go airborne. Fossil analysis ...

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 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 ...
