Fossilization is an extremely varied and complex process, and ultimately rare. Most of the time, only the hard parts of a living being can become fossilized, such as bones or the shell. In any case, for this process to take place, very specific conditions must be met: that the rock transforms (erosion phenomenon) without damaging the remains of the living being, that they are "cleaned" by scavengers. and by micro-organisms which eat the remains of flesh, etc.
Stone being a natural solid material, composed of one or more minerals, we can, in a very simplifying (and abusive way!) Consider that chemical processes can transform the hard remains of an organism into "rock".
