How does dirt and stone and such preserve bones and fossils?
In: Chemistry
In replacement, sediments and minerals replace bones, tissue, and shells. Often, these fossils have completely lost any original organic material they may have possessed, and are like exact copies of the original. There are other types of fossilization, but I think that’s the kind you were referring to.
In short, it doesn’t. You’re not looking at bones but fossils. Long story short, the bones get replaced on the molecular level with rock.
When it happens with trees, you get petrified wood. When it happens with bones, you get fossils.
