Scientists uncover flight clues in Archaeopteryx fossil, bridging reptile and bird evolution.

Scientists have uncovered new details about Archaeopteryx, an ancient bird, through a highly preserved fossil at the Field Museum in Chicago. Using CT scans and UV light, they discovered specialized feathers called tertials, which suggest the creature had flight capabilities. The fossil, dating back 150 million years, also shows reptilian traits like teeth and claws, alongside bird-like features. These findings, published in Nature, offer fresh insights into the evolution of flight.
