Posted on 05/22/2014 2:17:38 PM PDT by BenLurkin
Using a new "camera obscura" technique - inspired by Leonardo da Vinci - scientists have captured some of the clearest ever images of Archaeopteryx.
For the first time, they can see the complete skeleton in 3D. Not just the surface outlines, but all the hidden bones and feathers too.
They hope to discover how "the first true birds" evolved from feathered dinosaurs and took flight.
And what's more, to answer a riddle that has puzzled palaeontologists for 150 years. Could Archaeopteryx fly, or not?
In the past, large fossil slabs were too bulky to be scanned in a synchrotron light source - a type of particle accelerator which generates high-energy X-rays.
But now scientists here are experimenting with a clever new trick, inspired by a very ancient and simple idea - the pinhole camera
... In a synchrotron, the pinhole system allows large fossils - too bulky to be rotated and scanned via conventional techniques (such as tomography) - to be captured in full by an extremely narrow X-ray beam.
"It's a beam that's only the thickness of a human hair. But extremely powerful. If you stood in front of it you would be killed," says Dr Paul Tafforeau, a palaeontologist at ESRF.

Undoubtedly, that could fly! But only if you fermented up a batch of wild berries and distilled them sufficiently before happy hour!
Looks like a turkey with mange.
He probably could glide in any event.
a synchrotron... If you stood in front of it you would be killed
Synchrotron on kill.
Prehistoric yard bird.
Alhazen beat Leonardo to the optics involved a few hundred years earlier.
Some days the chicken eats you!
We’d need one of the FRenginners to weigh in on it.
The answer may be that range could be increased by putting more feeding it the ray.
But, would it kill quickly enough to be useful?
turkey-lurkey was right, the sky did fall, who knew,

many many more, its a hoax.

I need this fore the neighborhood teenagers!
You must be joking.
Most likely a runner rather than a flyer.....
