Intermediate Fossil Feathers Found

Bookmark and Share

A piece of amber formed of tree sap from 100 million years ago has preserved crucial evidence of feather evolution.

Evolution has long predicted the evolution of birds from reptiles, and recent discoveries of feathered dinosaurs has proved that model correct. However, the dinosaurs feathers found to date have been primitive in form, while bird fossils exhibit complex, barbed feathers required for flight.

This new fossil feathers, discovered in France, are intermediate in form between the simple downy feathers of early avian dinosaurs and the complex flight feathers of birds.
