Over the last two decades, thousands of fossils unearthed in China’s Liaoning Province have confirmed what paleontologists long suspected: Dinosaurs rocked feathers long before birds took to the sky. The findings debunk the theory that feathers evolved specifically for flight, and opens a Pandora’s box to the other purposes they may have served.

What type of protein is in a bird’s beak?

Birds’ beaks have an outer shell of hard keratin which consists almost entirely of proteins which are very rich in glycine [about 30 residues per 100 residues (residues %)], contain moderate levels of tyrosine and serine (each about 8 residues %), and which have relatively low contents of cystine (a …

What is keratin made of?

Keratin (/ˈkɛrətɪn/) is one of a family of fibrous structural proteins. It is the key structural material making up hair, nails, feathers, horns, claws, hooves, and the outer layer of skin. Keratin is also the protein that protects epithelial cells from damage or stress. Keratin is extremely insoluble in water and organic solvents.

Some birds use feathers for a variety of odd purposes that are certainly possible and plausible that these were used this way in some dinosaurs.

Why did dinosaurs fly so well?

“They had the body and biology perfectly suited for flight — they were small, they had wings, they could grow fairly fast and probably had a high metabolism, and those were the right cocktail of ingredients to begin playing around in the air,” Brusatte says.

Sinosauropteryx. Described in 1996, it was the first dinosaur taxon outside of Avialae (birds and their immediate relatives) to be found with evidence of feathers. It was covered with a coat of very simple filament -like feathers. Structures that indicate colouration have also been preserved in some of its feathers,…

What was the purpose of dinosaur feathers in amber?

The amber contained dinosaur (and bird) feathers from the Cretaceous Era some 75 or 80 million years ago. Also, fossil impressions of dinosaur skin contained quill-like protofeathers. The purpose of dinosaur feathers was mostly for insulation.

Why did some dinosaurs fly?

There are two main theories. It could be that these dinosaurs’ feathers provided an extra bit of lift when they were chasing prey or running away from larger predators; natural selection favored increasing amounts of lift, and finally one lucky dinosaur achieved takeoff. In contrast to this “ground-up” theory,…

What is an example of a feathered dinosaur?

Archaeopteryx, one of the first feathered dinosaurs, is an example of a transitional fossil, or one with features suggesting an intermediate stage between theropod dinosaurs and modern birds. Another feathered dinosaur, Deinonychus, used large claws to catch its prey, much like modern raptors.
