A 2014 study in Science – provocatively titled “A Jurassic ornithischian dinosaur from Siberia with both feathers and scales” – might just change how we think about all dinosaurs. Based on the age and identity of the specimen that the paper describes, the authors say perhaps all dinosaurs, not just the ones closely related to modern birds, had feathers! How cool is that?
“Probably that means the common ancestor of all dinosaurs had feathers,” says study lead author Pascal Godefroit of the Royal Belgian Institute of Natural Science in Brussels. “Feathers are not a characteristic [just] of birds but of all dinosaurs.”
