As expected honestly. They found "chemical signals" that indicate DNA in the fossil. Such thing can be anything, from contaminations to errorneous readings. To sequence that supposed "DNA" is a whole other level of technology. In fact, it would be so complex that unless they are hiding alien tech somewhere, I dare say we can't do it at all with our current level of technology.
Researchers explain that the markers cannot be of the microbial origin because they were chosen to only stain DNA in dead cells, and that those markers were highly concentrated at where DNAs would originally have been before the death. So assuming no other obvious mistakes, there may be short (6+ bp) but still readable DNA strands in the fossil.
That's so short though that it isn't really useful. It would be like piecing together a book given syllables.
Yeah, 6 bp would be too short to be useful. But something like 50 bp would be much more useful, and haven't yet been exactly precluded.
If there is anything at all... it would pretty much require rewriting the book on DNA preservation, given what we know about this right now I'd say 'impossible' but if there ever is any solid evidence to the contrary I'll be more than happy to admit that I was wrong.
