Mold and cast fossils are related but not the same thing. A mold fossil forms when an organism decays and leaves an impression in the surrounding sediment, while a cast fossil forms when that mold is filled with minerals that harden into a replica of the original organism. In essence, a mold is an imprint of the organism, while a cast is a replica.
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.

Mold fossils are more common than cast fossils. Mold fossils are formed when an organism or object leaves an impression in sediment that hardens into rock, while cast fossils are formed when a mold is filled in with minerals or sediment, creating a replica of the original organism or object.

a mold. this is for you Brandon
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.
no
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.

Pottery, casts... You make a cast from a mold. Your dentist may have made a mold of your teeth. From that mold, he can make you a night guard to fit your teeth exactly, to stop grinding your teeth. What he makes is a cast of the mold
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.
