Salt dissolving in water is a chemical change, the white residue is left when the water gets saturated by the salt and the salt starts to come out of solution to gain equilibrium. The residue can also be left behind when boiling off the water.

It is the carbon residue remaining from the organism or part of an organism that has been fossilized. Essentially what happens is that the organism is buried within a layer of sediment which solidifies. A chemical reaction takes place in which many of the elements that compose the organism are converted to gases and driven off, leaving behind a carbon residue (distillation) - and an outline of the original material.
