Archaeopteryx: X-rays shine new light on mystery 'bird'

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.

"Was he a little dinosaur running, climbing trees - or was he flying?

He probably could glide in any event.

a synchrotron... If you stood in front of it you would be killed

Synchrotron on kill.

Taller than a man, this chicken from hell could roller skate, sing the alphabet, and generally annoy the other dinosaurs. He was absolutely clueless of how to survive the asteroid impact, however.

Alhazen beat Leonardo to the optics involved a few hundred years earlier.

I wonder if the x-ray machine could be made into a weapon?

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?
