Today's Topic
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.
Join us on this page for a live chat at 3 p.m. EDT on Thursday, 7 July, to learn about the latest insights into what ancient birds, fish, and dinosaurs really looked like—and how their appearance may have affected their behavior and evolution. You can leave your questions in the comment box below before the chat starts.
