Long ago in the age of dinosaurs, a volcano in eastern China erupted and buried a host of strange creatures in ash, creating exquisite fossils that preserved a big surprise – many dinosaurs were covered in feathers.
In The Four-Winged Dinosaur, we investigate the most bizarre of these feathered dinosaurs, which has rekindled a fierce, decades-long debate over the origin of bird flight.
