Dinasours May Have Been Covered In Feathers

September 04, 2005 Dinosaurs may have been a fluffy lot Jonathan Leake, Science Editor THE popular image of Tyrannosaurus rex and other killer dinosaurs may have to be changed as a scientific consensus emerges that many were covered with feathers. Most predatory dinosaurs such as tyrannosaurs and velociraptors have usually been depicted in museums, films and books as covered in a thick hide of dull brown or green skin. The impression was of a killer stripped of adornment in the name of hunting efficiency. This week, however, a leading expert on dinosaur evolution will tell the British Association, the principal conference of British scientists, that this image is wrong. Gareth Dyke, a palaeontologist of University College Dublin, will tell the BA Festival of Science being held in the city that most such creatures were coated with delicate feathery plumage that could even have been multi-coloured. Fossil evidence that such dinosaurs were feathered is now “irrefutable”. “The way these creatures are depicted can no longer be considered scientifically accurate,” he said. “All the evidence is that they looked more like birds than reptiles. Tyrannosaurs might have resembled giant chicks.” The latest visualisation suggests that parts of Walking with Dinosaurs, the acclaimed BBC series, cannot be seen as scientifically valid. Similar criticisms might also be levelled at the Hollywood blockbuster Jurassic Park. The Natural History Museum in London, which has a popular exhibition of robot dinosaurs, conceded this weekend that some of its permanent displays may have to be adapted to reflect the new findings. The feather revelation follows a series of discoveries in fossil beds at Liaoning in northeast China where a volcanic eruption buried many dinosaurs alive. It also cut off the oxygen that would otherwise have rotted them away. Some theropod (“beast-footed”) dinosaurs were preserved complete with feathery plumage. Theropod is the name given to predatory creatures that walked upright on two legs, balanced by a long tail. The feathered finds include an early tyrannosaur, a likely ancestor of Tyrannosaurus rex, two small flying dinosaurs and five other predators. Feathers are thought to have evolved first to keep dinosaurs warm and only later as an aid to flight. Such finds are significant in linking dinosaurs to modern birds. Most palaeontologists accept that birds are descended from dinosaurs but there is fierce debate over how this happened. At the Dublin conference, Dyke will present new evidence suggesting that dinosaurs evolved the ability to fly and that some even developed all four limbs into wings.

Dinosaurs never existed.

None of the Dinosaurs I've seen had feathers.

Can't we just ask Bucc what they looked like?

Who covered them and where did they get the tar before dinosaurs became extinct?

This is a theory that has been gaining favor for a while now. Dinosaurs roamed the Earth for so long that it is likely they under went numerous evolutionary changes. It's entirely possible that both views of dinosaurs were correct; they they were mostly land-based animals without feathers and slowly developed feathers to help keep warm and eventually developed wings to aid in travelling to food and water. This would have happened over millions of years. Mother Nature's a mad scientist.

I always love lines like this people are aware that Jurassic Park was a movie, not a documentary, right? That the dinosaurs in the movie didn't have feathers is one of the least logic-defying aspects of the film. :)

They were shrunk down to bird size in the popular dinosaur movie.......Honey I Shrunk the TRex. Looked like a good idea, so it became the trendy thing to do. Everybody did it.

I suggest that we consult with Carl Everett before we take this discussion any further.

I thought Jurrasic Park 3 had added feathers of some sort to the Raptors because newer scientific evidence had suggested their avarian roots.

Very cool.

An interesting read

SI

Damn it! The Toronto Raptors will now have to change their logo that has alway been the epitomy of cool.
