Paleontologists have unveiled Auroradromeus polyfeather, a new genus of herbivorous dinosaur that shows evidence of complex feather structures across its back and tail. Found in the Jehol Biota of Inner Mongolia, this discovery challenges the long-held notion that feathers were primarily restricted to theropods, suggesting that primitive plumage was far more widespread across different dinosaur lineages than previously understood.
The specimen is remarkably preserved, showing filamentous integument and soft tissue impressions around the hip and tail. Researchers believe these feathers served a thermal regulation purpose, allowing the dinosaur to survive in the fluctuating temperatures of the Early Cretaceous forests. The discovery marks the first definitive evidence of feathers in this specific branch of the ornithischian family tree.
