Palaeontology: Scales, feathers and dinosaurs
Xing Xu1
Abstract
A fossil dinosaur that 'nests' with feathered relations in the dinosaur phylogenetic tree did not, it seems, have feathers. The discovery will encourage a re-evaluation of feather evolution.
Only birds have feathers — or so we thought until the discovery of fossils of feathered dinosaurs in China and elsewhere1. Since then, palaeontologists and biologists have together been painting a simple picture of feather evolution based on evidence from fossils and from developmental biology.
