X-RAY VISION UNLOCKS ANCIENT MYSTERIES OF FLYING REPTILES
from The San Francisco Chronicle

In the age of the dinosaurs, some of the most skilled hunters were sharp-
eyed flying reptiles that used their specialized brains, elaborate guidance
systems and some fearsome weaponry to snatch their prey while diving in
high-speed flight.

Now, researchers studying the fossilized skulls of those long-gone
creatures are reporting fresh insights into just how they evolved to do it.

Fossil experts have long been frustrated by the fact that only the bones of
ancient animals survive in fossil form, while their crucial soft tissues,
like muscles, nerves and brains, simply rot away after death and never
fossilize.

That limitation is ending now, thanks to advanced X-ray imaging technology -
- much the same as the CT-scans doctors use to picture the inner organs of
human patients.
