"The most recent and spectacular examples would be the assorted soft tissue finds in dino bones. no one believed it could last millennia ,stu, [less you can quote otherwise] till it was admitted that it really was in the bones.
so now you say it demonstrates it can last that long!
it all goes to show IMO that evolutionism cant be falsified - you just move the goal posts!"

You have to understand there ARE NO GOAL POSTS, that's not what science is about, we do not deal in absolutes (in my experience, only fools do). This is a learning process for us all, and although no-one believed intact soft tissue could survive such a long period of time, no-one would have ruled it out with evidence one way or another. Now we are finding evidence.

The work is by Mary Schweitzer, and I've seen a couple of her talks (and talks taking an opposing view) regarding the preservation of soft tissues in a T. rex limb bone.

If Schweitzer's findings are borne out then we move on, that's how science works. Also, palaeontology is using a range of cross-disciplinary techniques to study ancient life, including the discovery of the preservation of structural colours in feathers that tell us what dinosaurs looked like in life.
