UV light and CT scans helped scientists unlock hidden details in a beautifully-preserved fossil Archaeopteryx

Archaeopteryx is the fossil that clearly demonstrated Darwin's views. It's the oldest known fossil bird, and it helps show that all birds -- including the ones alive today -- emerged from dinosaurs. And while the first Archaeopteryx fossil was found more than 160 years ago, scientists are continuing to learn new things about this ancient animal. A set of feathers never before seen in this species help explain why it could fly when many of its non-bird dinosaur cousins could not.
