Dinosaurs

I'm not talking about Fortran, I'm talking about the actual reptiles here. Or protobirds. For as long as I can remember I believed that fossilized bones are just a poor substitute for real genetic information and people use it only because dinosaurs happened to die out without living too many descendant lines. But having seen this BBC documentary I was shocked how much behavioral information they could get from just a bunch of bones plus some experimentation. In addition to scientific value it's simply awesome. Links: part 1, part 2.
