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 dinosaur 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."

      As noted, the correct statement is that DNA (of all known organisms) directly encodes exactly 20 different amino acids. There can be a few more, but they are not directly encoded, but added/modified later.

      nope, same 20 amino acids now as then, they were just able to identify a sequence that was 149 amino acids long. however, you bring up a good point. I wonder if their experiment was designed to detect amino acids that no longer exist in modern animals. However, the fact that the same amino acids are shared across all living organisms known today (which diverged billions of years ago) makes it unlikely that there were different amino acids in animals 65 million years ago.

    Yeah, this is why there's so little known of the actual tissues of critters that old. But it's really an example of the "long tail" statistical phenomenon. Proteins, DNA, etc usually disappear pretty quickly, but there's no sharp cutoff age at which all samples instantly disintegrate into their constituent atoms. The decay is an exponential process, and no matter what age you pick, there's a small nonzero probability that there are fossils that old, until you get back to an age when there were no "tissues" on Earth. A very few fossils have been found that contain proteins that date to tens of millions of years. The story a couple of years ago about such a T. Rex fossil was an example that got lots of attention, mostly because it's such a popular dinosaur. But there aren't many people studying such fossils, because we haven't found very many of them.

    The T. Rex tissues survived because they were inside intact bones buried in a place that has been dry for some 70 million years. The overlying material was never heavy enough to crack the bones, and the internal humidity never got high enough for any embedded bacterial spores to come to life. This is highly unlikely, but in a few places it has happened. Nobody knows whether we'll find more, though. It's possible that we've found the only such fossils that exist on the planet. Or there may be more buried in Montana, where both of these fossils were found. That area has been dry for a rather long time.

    People are also considering the possibility of finding some very old frozen fossils under the Antarctic ice. But if they exist, they're in places that are sorta hard to get at. And the researchers want to be extra careful, because they expect that there will also be living spores (and maybe seeds) there, too. They don't want anyone doing the digging until they can be certain that the samples won't be contaminated by surface bacteria. But the digging (or more likely drilling) will probably be tried within the next decade or two.
