BBC News - Who, What, Why: What is the method for reconstructing Richard III's face? Feb 06, 2013

 "Bones found in a Leicester car park have been confirmed by DNA testing as those of Richard III. But what was the technique scientists used to reconstruct his face?
The only thing scientists had to go on was a skull. No portraits of the king done during his reign survive.
And yet scientists have built a model of Richard III's face. How?
Richard died in 1485 but his bones are well preserved. This doesn't surprise anthropologists as in the right conditions - soil with low acidity and few bugs - bones remain pristine for thousands of years.
The team of scientists at Dundee University doing the facial reconstruction never got near the bones. They were sent CT scans and photographs of the skull, which they ran through a computer programme.
At this point no-one knew if it was Richard III or not, says Caroline Wilkinson, Dundee University's professor of craniofacial identification. It was crucial to ignore any existing preconceptions about what Richard looked like. The shape of the face had to be based entirely on the scans."
