Yup! (heh heh).

Without even having to resort to quantum decay timelines.

Fossilization is a process where actual organic tissue is replaced by inorganic mineral deposits leaving a remnant of the original in it’s original form, but with no organic material intact.

In short, a true “fossil” is actually a form of stone, (like the “trees” in the Petrified Forest), while a bone is…well, a bone!

Only a blind idiot couldn’t tell the difference. (Actually, a “blind idiot” could weigh the two and tell the difference for that!)

Peace.

And EVERYONE have a Happy New year.
