Sinornithosaurus was the fifth and most bird- like feathered dinosaur species ever to be discovered. It lived about 125 million years ago and was a dromaeosaurid. Its discovery strongly suggests that other dromaeosaurids may have also had feathers. Some scientists believe that its discovery is proof that feathers first developed in quick-footed, ground-dwelling dinosaurs, instead of those that lived in trees
