We think that feathers evolved. We have several fossils that support this theory. But our fossil asks some questions

In other words, they don't know anything.

Feathers may have evolved early but then were replaced by scales in some creatures because they were not needed.

Humans may evolve organs that allow us to breathe liquid gold. But these organs may eventually disappear from the human race, because they are not needed.

Is that how evolution works?

"Scientists had thought that all representatives of the group coelurosaurs should have feathers," Gohlich told Reuters.

Maybe he was a 'plucker'.

Not found in China? If unique to Europe this might explain some folk tales.

Yup. Wonderful thing, science. It incorporates new evidence, rather than just closing its eyes, sticking its fingers in its ears and humming real loud.

I thought feathers evolved to satisfy a costume need in burlesque theater.

Yet.

Fossil find prompts rethink on dinosaur feathers
Yahoo (Reuters) ^ | 3/15/2006 | Patricia Reaney

LONDON (Reuters) - A newly discovered, perfectly preserved fossil of a 150 million-year-old dinosaur found in southern Germany may force scientists to rethink how and when feathers evolved.

The nearly complete remains of the chicken-size dinosaur named Juravenator, which is described in the journal Nature on Wednesday, were preserved in limestone. But unlike other members of the group of two-legged meat-eating predators known as coelurosaurs, it had no feathers.

"It is an absolutely new dinosaur that was not known before," said Ursula Gohlich, a palaeontologist at the University of Munich in Germany.

Remains of small dinosaurs from the Late Jurassic period are rare finds. The new fossil is nearly complete, apart from a missing part of its long tail, and shows soft tissue and an imprint of the skin but no feathers.

"Scientists had thought that all representatives of the group coelurosaurs should have feathers," Gohlich told Reuters.

"Now we have a little dinosaur that belongs to coelurosaurs that does not show feathers. This is a problem."

COMPLEX EVOLUTION

Feathers were thought to have evolved very early within coelurosaurs. All members of the group were thought to be feathered.

But Gohlich and Luis Chiappe, of the Natural History Museum of Los Angeles County in California, believe the evolution of feathers may be more complex than previously thought.

Feathers may have evolved early but then were replaced by scales in some creatures because they were not needed.

"Another possibility perhaps is that some representatives of coelurosaurs were not entirely covered with feathers, only certain areas," said Gohlich.

The newly discovered Juravenator was very young so may not have lived long enough to develop feathers. But Gohlich said that despite its age, she would have expected it to have had feathers.

"We think that feathers evolved. We have several fossils that support this theory. But our fossil asks some questions," she added.

The oldest known bird, Archaeopteryx, was also found in southern Germany. It too lived about 150 million years ago and had feathers but it is uncertain whether they were used to fly or to keep warm.

Xing Xu, of the Chinese Academy of Sciences in Beijing, said whatever the explanation, the discovery of Juravenator has enriched knowledge of early feather evolution. It could also indicate where future research could be concentrated.

"Juravenator may complicate the picture, but it makes it more complete and realistic," he said in a commentary in the journal.

The "feathers" look like a form of mold that grows on dead bodies even to this day.

Exactly. Thanks to this fossil find, we now have another piece of evidence that can be used to more exactly discern the evolutionary link between birds and their reptilian ancestors. Great article!

Another possibility is that the feathers may have been removed before the corpse was fossilized. My folks have chickens on their farm and some of them are plucked half bald by other chickens. I've also seen a few chickens after the coyotes have ripped them up and there is a nice skeleton left over with most of the meat, skin and feathers gone.

Good article... of course there are going to be people who think, "Ah Ha! Evolution is wrong!". They are of course grasping at straws.

The answer is simple - it got plucked before it died. Maybe Space Aliens, maybe Noah was hungry. The possibilities are endless.
