Seven dino-era feathers found perfectly preserved in amber in western France highlight a crucial stage in feather evolution, scientists report.

The hundred-million-year-old plumage has features of both feather-like fibers found with some two-legged dinosaurs known as theropods and of modern bird feathers, the researchers said.

This means the fossils could fill a key gap in the puzzle of how dinosaurs gave rise to <A href="http://animals.nationalgeographic.com/animals/birds.html" linkindex="52">birds</A>, according to a team led by Vincent Perrichot of the Museum für Naturkunde-Berlin in Germany.

The find provides a clear example "of the passage between primitive filamentous down and a modern feather," said team member Didier Néraudeau of the University of Rennes in France.

The study team isn't sure yet whether the feathers belonged to a dino or a bird.

But fossil teeth from two dino families thought to have been feathered were excavated from rocks just above the layer that contained the amber, Perrichot said.
