The biggest “patch” of fossilized skin was about 1’ square. It’s a lot more likely that this “soft” tissue, which is only found in very small amounts, requiring a microscope to see, is preserved by an accident of the way the minerals accumulate during the fossilization process i.e. an airless environment deep inside a thick mineralized bone.

And how is that NOT my analogy of the fossilization forming around the tissue in question and preserving it like canned food?
