Answer

Brief Explanations:

A mold fossil forms when the hard parts of an organism dissolve, leaving an impression in the surrounding sediment. Preservation in amber creates an amber - preserved fossil, replacement by minerals forms a petrified fossil, and filling a mold with sediment creates a cast fossil.

Answer:

Hard parts of the organism must dissolve.
