It is a cast fossil.
Cast
A mold fossil forms when an organism's hard parts dissolve and leave a cavity that later fills with sediment, creating a replica of the organism's shape.
igneous rock
When an Igneous rock is broken down by physical processes it can become sediment, carried along rivers and waterways to reach the sea and the oceans. When upon the seabed, it is slowly covered by other sediment, and the combined force of the water above and sediment above working with sea mud and other sea deposits forms sedimentary rock.
It is known as moraine.
Cast
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.

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.

The type of fossil that forms when an organism's hard parts dissolve, leaving a cavity that later fills with sediment, is called a cast fossil. This process typically begins with the original hard parts, such as bones or shells, being buried and eventually dissolving due to chemical processes. The resulting cavity can then be filled with minerals or sediment, creating a cast that reflects the shape of the original organism. Cast fossils provide important insights into the morphology and structure of extinct species.
When the metamorphic rock breaks down into sediment. Thus, making the new rock sedimentary because when sediment forms together over time it makes it sedimentary rock
not a hydrogenous sediment?
no they do not
you cant have a scab without a clot, the clot forms when the blood coagulates (becomes thick and basically fills the hole, over time the scab forms and uses the clot like scaffolding to fill the gap with new cells, when its done falls off.
A sediment deposit called a windward slope forms when sediment is blown against an obstacle and settles behind it. This deposit is characterized by a gradual slope facing into the prevailing wind direction.
forms a sediment when it sinks to the bottom of a liquid.
