Dinosaur Fossil Found With Preserved Soft Tissue

damn_registrars writes "A fossilized hadrosaur has been uncovered in South Dakota that has preserved soft tissue. This is described as a "mummified" dinosaur, and allows for a look at the skin and musculature of some parts of this animal. The find was reported by a 24 year old Yale graduate student of paleontology."

jd writes "Fossilized skin from a dinosaur in China is allowing paleontologists a better understanding of what dinosaur skin was like. A tear, caused by a predator, shows that below the scales of the Psittacosaurus was a thick hide comprised of 25 layers of collagen. Other than the multitude of layers, this is very similar in nature to modern shark skin. The gash caused by a predator allowed the skin and the soft interior to be fossilized along with the bones. This is not the same dinosaur that had been reported previously on Slashdot, which was found in South Dakota, although the process and extent of fossilization is very similar."

    According to the FTA, the find was originally located in 1999, and partially excavated in 2004 with a full investigation commencing in 2006. Having never studied archeology or paleontology, is it common for sites like this to be passed by even though there is something located there?

      Dinosaurs can be big. Really big. I mean, you may think ...

      Oh, wait, wrong analogy. Seriously though, the phrase that is most relevant to answering your question is in the article: "10-ton block", plus another 4 tons, which they whittled down to "only" 5 tons in total. This is not your usual fossil extraction task. It can take significant money and time to set up what is needed to excavate a find that big, you have to transport it, and you have to find a spot for it back in the lab after you do extract it. This is back-breaking, painstaking work, and getting together a big enough chain gang^H^H^H^H^H^H^H^H I mean group of volunteers to do the job isn't always easy, especially when there may be a dozen other sites in the region where excavations are already under way, and to which the resources you have are already allocated. So, sometimes a site gets marked with its GPS coordinates and hidden until the resources are available. Also, sometimes you have to start the excavation before you really realize the importance of what you have found. That seems to be the case for this specimen, based on the comments in the article. They didn't originally realize how special it was.

      So, yeah, what you describe is common, especially in areas that are both remote and prolific, and especially for large dinosaur specimens. It can take years.

      According to an archeology professor of mine at Queen's University, this is very common. Excavation is a slow process, and one which is dependent on the weather. Furthermore, it is a funding intensive project.

      You find a site, then you apply for funding. When you get your funding, you start the dig. Generally you only get the summer as rain, snow or ice can damage artifact and generally make digging harder. At the end of the digging season, you place some sort of modern marker at the edges and bottom of the trench (my professor used soda cans) and fill them in until the next time you can come back.

      If your site proves to be interesting, you can get the funding renewed for another summer, and as a rule of thumb they give you funding every 2 years. This allows the funding to be spread out over a wider range of projects, and ensures the scientists have the time to publish what they found during the excavation.

          The cans he's talking about are buried at the edges of the excavation as it's being filled in, in order to define the limits of the previous trench. Then when you come back the next year you can quickly remove your fill dirt. The idea is to use something unmistakably modern (i.e. not a rock). You wouldn't pick them up unless you were digging at the site. If you're digging for litter, well, I admire your dedication, but you're being overzealous.

    Although it is described as "mummified," the 65 million-year-old duckbilled dinosaur that scientists have named Dakota bears no similarity to the leather-skinned human mummies retrieved from ancient tombs in Egypt. Time long ago transformed Dakota's soft tissue into mineralized rock, preserving it for the ages.

    This isn't the first time they've gotten soft tissue from a dinosaur. A few years ago, they were trying to haul some dinosaur bones from a dig site by helocopter, but the bones wouldn't fit. After trying to solve the problem several ways, they made the agonized decision to break some of the largest bones. When they broke them open, they found soft tissue in one of them (I think it was a femur). A friend of mine (getting his phd in bioinfomatics) mentioned that they had managed to extract dinosaur proteins from this, and that because proteins are much more unstable then nucleic acids, it was entirely likely that they could extract dinosaur DNA from the specimen.

The Discovery Institute's discovery was discovered in the remote Dusty Rivers area of southwestern Arizona. A spokesman for the paleontological team said that the dinosaur saddle provides irrefutable proof that man and dinosaurs lived simultaneously, as predicted by most creationist or "intelligent design" doctrines.

      Some facts for you:

      1.) When cloning a sheep to give birth to itself, by putting a complete strand of its own DNA in its own egg cells in its own womb, we would have a one in several hundred chance of success. We don't know why, but the rest would be miscarriages, still births, or otherwise non-viable. The cloned animal would die early of old age, nobody knows why.

      2.) The Human Genome Project to sequence *ONE* complete set of DNA for a single human took us 13 years and 3 billion dollars. That's comparable to the Apollo project, to sequence *ONE* example of a complex being's DNA.

      3.) DNA is relatively unstable. I doesn't survive completely intact for 65 million years no matter how you preserve it.

      Mosquitoes trapped in amber wouldn't be great sources of DNA - it would have still decomposed over time. Not in the "something ate it" sense of the word, but in the "radioactive particles" sense of the word. So the DNA would be there, but fragmented. Analyzing one strand of complete, non-fragmented strand of DNA was an Epic undertaking. Doing it with hundreds of strands that were chopped into pieces is probably beyond our capabilities. We could also get this DNA from red blood cells found in a T-rex fossil recently, or just from grinding up the core of bones for *really* tiny bits.

      Next, you can't just patch DNA in a dinosaur with DNA from a reptile. It just doesn't work that way, and birds are closer relatives anyway if it *did* work that way.

      And then you'd have to somehow put together a DNA molecule. We can't do that yet. I'm totally serious, we can't. We can manipulate pieces maybe 10 or so genes long in existing DNA, but I don't think we could piece billions of genes long strands together from a blueprint even given all the time in the world.

      Finally, you'd need a viable dinosaur egg. You can't just pick someone else's egg and stick dino DNA in it, eggs are highly specialized. You might get away with something as similar as elephant-mammoth but there just isn't anything *like* a dinosaur, nothing *near* close enough for a viable egg.

      If by some miracle you managed to find full dino DNA, sequence the DNA, assemble the DNA, and put them in an artificial egg that worked... you'd have to do a thousand trials before you could say with any certainty you'd messed something up to make it fail instead of just having bad luck. So don't worry about Jurassic Park happening anytime soon.
    • That would be theoretically hard.

      With the mosquitoes technique you'll find in the end several fragment of DNA per mosquitoe, with no way to know if they come from the same dino or if its contaminent from the mosquitoe.
