This Paper just came out.
Nuclear preservation in the cartilage of the Jehol dinosaur Caudipteryx:jaw-dropp
I guess technically what they really did was use a stain that attaches to threads of chromatin. And it dyed the nuclear area of some de-siliconized cells found in a dinosaur fossil.:eye-poppi
However, apparently they have not gone further to more finely detect DNA base pairs specifically.
I have been told over and over that is completely impossible. The 1/2 life of DNA is just too short for it to last to the dinosaur ages.
But I was also told actual dinosaur tissue of any sort is impossible to last that long too, and there are more and more preserved dinosaur tissues being found all the time now. Mostly cartilage.
So what to think? Is this a new breakthrough? Or will it be yet another false alarm like the last few?
