Fossil
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.

When the organism is buried in sediment and then dissolved by underground water
A mold fossil is a type of fossil formed when an organism or plant decomposes or is buried in sediment, leaving an impression or hollow shape in the rock. The mold is created when the organic material decays and leaves behind a cavity that is later filled with minerals, preserving the shape of the original organism.
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.

Fossil
it is not true
it probably died there as the sediment was beginning to compact and left a trace fossil

Both copy the shape of its ancient organisms.a MOLD is a hollow area in sediment in the shape of an organism or part of an organism.a mold forms when the hars part of the organism,such as a shell,is buried in sediment.Later, water carrys dissolved minerals and sediment there,the result is a cast. A CAST is a solid copy of the shapes of organisms.a cats is the opposite of a mold.both mold and cast preserved details of the animals structure

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.
