Dinosaur coloration has always been a source of wild speculation. Artistic renders have ranged from the conservative (battleship grey, lizard green) to the flamboyant
, but all guesses appeared equally valid
. While there are some wonderfully preserved examples of dinosaur skin
texture, fossils have remained stubbornly monochromatic… until now. [more inside]

First Birds with teeth in 70 million years
. Vicious toothed, flying microraptors once darkened the Jurassic skies. Now, scientists
have learned to activate the dormant, vestigal avian "tooth gene" and so coaxed chicken embryos into growing teeth. From the grave, Alfred Hitchcock enviously quips - "a messy thing indeed when toothed birds kill a man". Meanwhile the French are appalled: “quand les poules auront des dents”, which translates to “when hens have teeth”, is analogous to the English “pigs might fly”. Coming soon: flying pigs.
But there might be a baldness cure in this new research. I'll remember that as the flocks of mutant raptor-fowl move in for the kill.

Birds are not descended from Dinosaurs.
The latest in the ongoing debate about the origin of birds and whether they evolved from dinosaurs or from a earlier common ancestor. Chinese scientists report the discovery of a 120 million year old bird fossil that had feathers and could clearly fly.
