Hadrosaur Proteins Sequenced

jd writes "In a follow-up study to the one on proteins found in a T. Rex bone, the team responsible for the T. Rex study sequenced proteins found in an 80-million year old Hadrosaur fossil. According to the article, the proteins found confirm the results of the T. Rex study, proving that what was found in T. Rex was not a result of modern contamination as had been claimed by skeptics, but was indeed the genuine thing, real dino protein. Furthermore, despite the new fossil being 12 million years older, they claim they got more out — eight collagen peptides and 149 amino acids from four different samples. This, they say, places the Hadrosaur in the same family as T. Rex and Ostriches, but that not enough was recovered to say just how close or distant the relationship was."
