Many people incorrectly think that a copy of a fossil is a 'mold'. But the real name for the copy of a fossil is a 'cast'.
A mold fossil is formed when an organism decays and leaves an impression in the surrounding sediment or rock. Over time, the impression fills with minerals, creating a cast of the organism's shape.
Fossil
No, a fossil formed when an organism buried in sediment dissolves is called a mold fossil. It is created when the organic material of the organism dissolves, leaving behind an impression or cavity in the sediment that hardens into rock.
The answer is Mold
It is conceivable that a fossil could be found among sedimentary rock crystals, and some dead organisms have actually been replaced by minerals which are composed of crystals. Fossils in gems and crystals from metamorphic or igneous processes--no.
The fossil that is formed when an organism is buried in sediment and hardens into rock is called a cast fossil, in which the empty space serves as a mold.
Sediment and tree sap
A mold fossil is formed when an organism decays and leaves an impression in the surrounding sediment or rock. Over time, the impression fills with minerals, creating a cast of the organism's shape.
It gets buried in sediment

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.
Collection of a volume of fossil-laden rock or sediment for analysis of fossil content.
No coral is NOT sediment. Coral SAND is a sediment but the coral itself is a living organism - if buried and lithified, the coral becomes a fossil.
it probably died there as the sediment was beginning to compact and left a trace fossil
a footprint.
