Dinosaurs: Fuzzy origins for feathers
Lawrence M. Witmer1
Abstract
Cretaceous fossil deposits in China are famous for their feathered dinosaurs. But the surprising discovery of a herbivorous dinosaur with a filamentous coat raises fresh questions about the evolution of feathers.
Liaoning Province in northeastern China is renowned for the fossils that document, in often vivid detail, virtually the entire biota that lived over a period of several million years during the Early Cretaceous (about 125 million years ago)1. Although exquisite fossils of diverse vertebrates, invertebrates and plants have been recovered, it's the spectacular feathered dinosaurs that have received most attention2, 3, 4 and caused much controversy5, 6.
