cast
No, a thin cavity in a rock showing where a shell has decayed is not considered a fossil. Fossils are the preserved remains or traces of ancient organisms, such as bones, shells, or imprints, that have been naturally preserved in rock or sediment over time. The empty space left behind by a decayed shell would be considered a mold or cast, not a fossil.
When remains of an organism dissolve and leave a cavity, it can result in the formation of a fossil mold. This mold can then be filled with minerals or sediment, creating a cast fossil, which preserves the shape of the original organism. Both mold and cast fossils provide valuable information about the organism's characteristics and environment.
Not necessarily. It may be just a fracture.
A mold fossil forms when an organism's hard parts dissolve and leave a cavity that later fills with sediment, creating a replica of the organism's shape.
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).
what kind of fossil is what!

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.

Cast
i think it would be a trace fossil.
coal is a type of fossil fuel hahahhah i think
This is called a trace fossil. or a mold.
