That’s why forensic scientists demineralize bones all the time to get at the soft-tissue contained therein. LOL

One doesn't need to demineralize bone to detect collagen on it.

Yet these FOSSILIZED bones needed to be demineralized.

Do you know the difference between a fossil and a bone?

Why is it that we find bones of modern species but not fossils, and why do we find fossils of dinosaurs but no bones?

An old trick! Soak a bone in vinegar and it becomes more flexible as the minerals are dissolved. Or a boiled egg works pretty well too as the shell softens.
