When the ancient reptile touched down, its feet pressed into soft mud leaving behind prints that fossilized and have now been identified.  After examining the preserved footprints, scientists determined that the pterosaur stalled in the air shortly before touching down, a technique also used by many modern birds. Scratch marks left...

A classic example of the posture, which has puzzled paleontologists for ages, is the 150 million-year-old Archaeopteryx, the first-known example of a feathered dinosaur and the proposed link between dinosaurs and present-day birds. "Virtually all...
