Is a thin cavity in a rock showing where a shell has decayed a fossil?
This is called a mold, a mold is when a fossil has a cavity in a rock, it turns into a fossil when it becomes a cast, so technically yes it is a fossil
What is the name for a copy of a fossil produced by filling a mold with sediment or crystals?
Many people incorrectly think that a copy of a fossil is a 'mold'. But the real name for the copy of a fossil is a 'cast'.
Which fossil type could contain preserved parts of a organism?
It is called a mold fossil, which can become a cast fossil. After the soft parts of the animal rot away, a cavity remains (the mold fossil) which becomes filled with hardened sand or mud (the cast 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.
