A rock fossil created when a buried organism dissolves

Real World Example

Imagine you left a cake baking in the oven and forgot about it, only to find it has completely burned and disappeared, leaving behind an indentation in the pan. This situation is similar to how a mold fossil is created when an organism buried in sediment dissolves, leaving an impression of its shape behind. Just as the burnt cake leaves an empty space in the pan that outlines its former shape, the dissolved organism leaves a cavity in the rock, capturing the intricate details of its structure, which geologists refer to as a mold fossil.
