Why Snakes Have no Legs (Random 3-d X-ray Imaging Science)

Check it out - the image above is of the leg bones of a snake!  Didn't know snakes had leg bones?  Me either!  I just saw this interesting press release on the the use of Synchotron-Radiation Computed Laminography to create high-tech 3-d images of fossils.  This isn't your ordinary every-day x-ray - the fossils are taken to a particle accelerator facility where intense x-ray beams are used to construct a three-dimensional reconstructed image.  This allows detailed measurements of the structure within ancient fossils.  Sounds like analysis of this particular fossil supports the idea that snakes evolved from burrowing lizards.
