tiny dinosaur may have dazzled mates with rainbow ruff and a bony crest




ancient dinosaurs were adorned in some amazing ways, from the horns of the triceratops to the plates and spikes of the stegosaurus. a newly discovered, bird-like dinosaur fossil from china contains evidence that could add a new accessory to the list: a shaggy ruff of rainbow feathers.



this new discovery could change the way we study dinosaurs




despite everything fossils can tell us about dinosaurs, a new study is changing some of the oldest research we have at our disposal. the study in question, published in the journal nature today, not only changes how some dinosaurs are classified, but also suggests traits of a common ancestor and sha...
