if the original organism dissolves or decays, leaving a hollow in the rock, that is a mold.
If the mold fills up with sediment which gradually hardens into the shape of the original organism, then that is a cast.
Casts are copies of fossilized plants or animals. Molds are hollow impressions of the fossil.

How is a cast fossil different from a mold fossil?
if the original organism dissolves or decays, leaving a hollow in the rock, that is a mold. If the mold fills up with sediment which gradually hardens into the shape of the original organism, then that is a cast. Casts are copies of fossilized plants or animals. Molds are hollow impressions of the fossil.
