In breakthrough, scientists identify dinosaur proteins - International Herald Tribune: "In a retrieval once thought unattainable, scientists have recovered and identified proteins in a bone of a well-preserved Tyrannosaurus rex that lived, died and was fossilized 68 million years ago.
The scientists say the success, attained with advanced research techniques, opens the door for the first time to exploration of the molecular-level relationships of ancient, extinct animals, instead of just relying on their skeletal remains."
