Its a Noun, and here is the definition:

A fossil formed when an animal, plant, or other organism dies and is covered by sediment, it flesh decays and bones deteriorate due to chemical reactions, and a cavity remains below the ground surface; the cavity's interior surface is an 'impression in the general form of the original organism's exterior surface.

What is cast fossil?

A cast fossil is formed when a mold fossil is filled in with minerals or sediments, creating a replica of the original organism. The mold is created when an organism decays or is buried in sediment, leaving an impression behind. Cast fossils can provide valuable information about the shape and structure of the original organism.


How does a cast fossil form?

A cast fossil forms when an organism dies and becomes buried in sediment. Over time, the organism's remains decay, leaving behind a cavity or mold in the sediment. The mold is then filled with minerals that harden and create a replica of the organism's shape, known as a cast fossil.


This type of fossil is formed when an organism is buried in sediment which hardens into rock After the soft parts of the animal rot away a cavity remains?

The type of fossil being described is a mold fossil. These fossils preserve the external shape of an organism by filling in the cavity left behind after the original organism decays. Mold fossils provide important insights into the shape and size of ancient organisms.


How is a cast fossil formed?

A cast fossil is formed when an organism dies and leaves an impression in sediment. Over time, this impression can fill with minerals, creating a replica of the organism's shape. The original organism then decays or is washed away, leaving behind the cast fossil.


How are mold and cast related?

The Cast is the fossil of the shell etc itself. The Mould is the hollow left in the surrounding rock if the fossil is removed artificially or by some natural event such as differential dissolution or mass-movement.

What is a mold fossil?

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.

A mold fossil is formed when an organism dissolves and leaves an empty space in a rock. This empty space can later be filled by other minerals, forming a cast fossil.


What is a mold and cast 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.


Which type of fossil is formed when an entire organism is filled with materials such as mud or clay and then hardens the entire organism and the filling?

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.

What is more often found - a cast fossil or a mold fossil?

Mold fossils are more common than cast fossils. Mold fossils are formed when an organism or object leaves an impression in sediment that hardens into rock, while cast fossils are formed when a mold is filled in with minerals or sediment, creating a replica of the original organism or object.
