Archaeopteryx (photo)

Retinal neuroscientist and photographer Bryan Jones sends in this gorgeous shot of an archaeopteryx fossil displayed in the Museum für Naturkunde in Berlin, Germany.

"As a biologist, seeing this fossil represents something of a pilgrimage," says Bryan, "[Visiting this museum is] a journey that all biologists would benefit from making."

Snip from his blog post:

This particular sample was found in the Solnhofen limestone formation in Bavaria and is the basis for the link between the dinosaurs and the feathered birds. Archaeopteryx itself is a feathered theropod, but is though of as the oldest documented bird dating back approximately 150 million years ago.

The fossil was found in 1874 by Jakob Niemeyer who traded it to Johann Dorr for a cow. Johann then sold the fossil to Ernst Haberlein for 2,000 German Marks. This sale was then turned around to the founder of Siemens, Werner von Siemens for 20,000 German Marks for the University of Berlin which has provided this specimen to scientists around the world as the best preserved specimen found with elegant feathers and an exquisitely preserved skull.
