In 1996, a fossil unearthed in China became the first confirmed record of a dinosaur covered in feathers.

Before this discovery, some palaeontologists had suggested that dinosaurs might have developed feathers and eventually evolved into modern birds, but the idea remained controversial due to the lack of concrete evidence.

Canadian palaeontologist Philip Currie was among the first experts to examine the specimen and recognise it as a feathered dinosaur. He tells Stefania Gozzer about the scientific debate the fossil ignited, as well as the challenges of accessing the specimen at a time when it was still difficult for Western researchers to study fossils in China.
