Proteins Found in Dino Bones

July 27, 2010
Ancient proteins have been found in the soft tissue recovered from the fossil bones of a 68 million-year-old Tyrannosaurus rex (T. rex) and a half-million-year-old mastodon.

These results may change the way people think about fossil preservation and present a new method for studying diseases in which identification of proteins is important, such as cancer.
