Wonderchicken: Oldest fossil of modern bird identified

Paleontologists say the finding proves birds existed in the northern hemisphere alongside dinosaurs around 67 million years ago.

The fossil, which is almost 67 million years old, could explain why birds survived an asteroid impact that killed most life on Earth.
