A fossil cast is a type of fossil formed when sediments fill in the hollow space left by a decomposed organism. The sediments harden into rock, preserving the shape of the organism in the form of a cast. This can provide scientists with valuable information about the size and shape of the original organism.

What do you call a mineralized trace of a living organism preserved in rock?

A trace fossil can be anything from a coprolite (faeces) to a footprint. It is anything which proves the creature's existence without being the actual creature itself. For example, an ammonite shell is proof of its individual existence, but its faeces give us little information about its appearance. A fossil could be a cast, mold, or true form fossil.
