What forms when a fossil mold is filled?
When a fossil mold is filled, it forms a fossil cast. The cast is a replica of the original organism or object that created the mold, made of the same material as the original organism or object. Fossil casts are valuable in paleontology for studying the morphology of ancient organisms.
How is a cast fossil formed?
A cast fossil is formed when an organism dies and leaves an impression in sediment. Over time, this impression can fill with minerals, creating a replica of the organism's shape. The original organism then decays or is washed away, leaving behind the cast fossil.
Is a cast fossil one kind of carbonized fossil?
No, a cast fossil is not the same as a carbonized fossil. Cast fossils are formed when minerals fill in the cavity left by a previously existing organism, while carbonized fossils are formed when organic materials are compressed and heated, leaving a carbon residue of the original organism. Both types of fossils preserve the shape of the organism, but through different processes.

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).
Which forms first a fossil mold or a fossil cast?
First, a thin layer of sediment hardens and forms a mold. Then, what is known as a cast is when a new layer of sediment fills in the mold breaking down the creature/ animal/fossil.
