Mold filled with minerals
The cast of Mold - 2012 includes: Andrea di Cocco Tom Kerr
To throw again., To mold anew; to cast anew; to throw into a new form or shape; to reconstruct; as, to recast cannon; to recast an argument or a play., To compute, or cast up, a second time.
All are indicative of the size and shape and possible habitat of the original organism.
Mould in Canada is spelled mold.

Mold is like cast in being a type of fossil .
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.
a mold is what you pour materials into to make a cast
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 fossil mold is formed by the impression left in rock by the remains of an organism. A cast fossil occurs when the mold is filled in by precipitating minerals.
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.
A cast.
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).
One form of fossil forms when an organism dies and its body is covered by layers of sediment. As time passes, the organism itself, particularly when composed primarily of softer materials, is eroded and carried away, leaving a negative imprint of its body. This type of fossil is called a mold. A cast fossil forms when a mold fossil is filled with some form of mineral, usually through the seepage of water depositing the minerals within the mold. In time, the mold is filled and the materials deposited harden, creating a replica of the original fossil. This is called a cast fossil.
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.
a Cast fossil is formed when the mold is filled with another material forming a cast.
