Mold is related to cast because they are types of fossilizations, where the physical characteristics of organisms are impressed onto rocks. Most impressions occur in coarse porous rocks such as sandstones.
The Cast is the fossil of the shell etc itself. The Mould is the hollow left in the surrounding rock if the fossil is removed artificially or by some natural event such as differential dissolution or mass-movement.
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.
A cast fossil is formed when a mold fossil is filled in with minerals or sediments, creating a replica of the original organism. The mold is created when an organism decays or is buried in sediment, leaving an impression behind. Cast fossils can provide valuable information about the shape and structure of the original organism.
When the animal dies its skeleton settles on the sea floor and is buried by sediment. that thickens and begins to turn to stone. The skeleton dissolves and a mold is formed. Minerals crystallize inside the mold and the cast is formed.
A mold or cast of a fossil can provide insights into the size, shape, and structure of the organism, helping scientists understand its habitat and behavior. By studying the details preserved in the mold or cast, scientists can make inferences about the environmental conditions in which the organism lived, such as whether it lived in water or on land, its feeding habits, or its interactions with other organisms.

A MOLD is used to make a cast.
a mold. this is for you Brandon
Mold is like cast in being a type of fossil .
a mold is an impression of an organism. a cast is a mold filled with sediment
a mold is what you pour materials into to make a cast
A mold and cast fossil is and exact stone replica of an organism but it is formed like this. The first layer of sediment hardens and forms a mold. then a new layer of sediment fills in the mold and hardens. That is the cast.
There are mold and cast fossils in many local creeks, streams, and/or rivers.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.Its a Fossil.

Mold
That in which metal is cast; a mold., A bar or wedge of steel, gold, or other malleable metal, cast in a mold; a mass of unwrought cast metal.
