Ancient Fossilized Bone Marrow Found 38

Posted by timothy on Monday July 24, 2006 @05:04PM from the not-so-squishy-anymore dept.

anthemaniac writes "Last year scientists recovered soft tissue from a T. rex. Now LiveScience is reporting that researchers have found fossilized bone marrow, the first discovery this this type of soft tissue, in frog and salamander fossils dating back 10 million years. Since the bone marrow was discovered 'in an environment vastly different form the one in which the T. rex soft tissue was found,' scientists now hope they'll find soft tissue in other environments and maybe from ancient mammals."

I wonder if they can sequence the protein segments too (I hope there are some) and we should be able to find more of the links with birds. And most importantly can they isolate DNAs as well ? It has been a while (yeah long time).

  mtDNA is shorter and usually more stable than nucleic DNA, so I wouldn't rule out the possibility of finding some. They don't exactly need the whole molecule, just enough to be able to determine where in the mtDNA strand the segment belongs -and- get a good idea of the extent of the changes.
  
  Even if they can just get proteins, provided it's a random sample and statistically significant, they may be able to deduce things about the nucleic DNA. They'd know the proportions of the proteins in dinosaurs, the proportions in likely candidates for nearest living relatives now, and the DNA coding for those proteins in those living relatives. From that, they could deduce, using reverse-engineering techniques, what changes would have been needed to go from the ratios of the past to the ratios of the present.

  It's a subtext metaphor: we are giving them "42" - the secret of Life, the Universe, and Everything - which is symbolic of the continual flow of our technology and military secrets to them.
  
  Now you try it: what would the subtext be if the report had said 69 cartons of dinosaur eggs?

  Haven't heard those news, but it's probably true. China is a dinosaur treasure trove, and illegal fossil trade is a big biz here. The Chinese goverment is cracking hard on the smugglers, and if smuggled Chinese fossils are found abroad, they are usually returned to China (fossils are by default the property of the country they are found in). And in case you didn't know, dinosaur eggs are quite common as fossils. Of course they're rock now, no actual soft tissues there.

It could be great. We could use frogs to fill in the gaps in the DNA and then just use cloning to make dinosaur attractions.

All we ever seem to see about the soft tissue claim is references back to the original press release. What claims have been published in the peer reviewed literature, and how have those claims been received?

As I understand it, what actually happened is that there was some "stuff" in the holes where blood vessels formerly flowed through the leg bones, and it came out when a solvent was applied. Then came the press release; I haven't seen any stories about the eventual analysis of the material, and the lengthening silence makes me wonder whether the press release was a jumped conclusion.
