It also gives some indication that many of the animals found died and were preserved immediately. I look forward to more details on this one coming out.
Thanks for ping!
You’re mistaken. The find was of FOSSILIZED soft tissue. You can read all about it direct from the scientists themselves right here:

It seems to me there's only two choices: either these soft-tissue fossils are as old as scientists think are but, as the original story says, "soft tissue can be preserved under a broader set of fossil conditions than previously known." Or, they are so young that no extraordinary explanation is required for why soft tissue is preserved. If that's the case, why doesn't every fossil have soft tissue inside it? Why is it so rare--why does it require microscopes to find--if the simple explanation is that it's not very old?
