Today at 3 PM EDT, AAAS will be running a live chat on the color of prehistoric creatures.
Thanks to thousands of fossil discoveries, scientists know a great deal about the creatures that inhabited our world millions of years ago. But one thing still vexes them: Just what did these animals look like? Scientists may finally get a chance to color-in this ancient world, thanks to new techniques that are revealing pigments in fossilized feathers and other soft tissues.
This chat is part of a new venture, called ScienceLive, where it bring its readers in touch with prominent scientists on a weekly basis so they can ask questions on the hottest topics in science.
