What are cast fossils?
One form of fossil forms when an organism dies and its body is covered by layers of sediment. As time passes, the organism itself, particularly when composed primarily of softer materials, is eroded and carried away, leaving a negative imprint of its body. This type of fossil is called a mold. A cast fossil forms when a mold fossil is filled with some form of mineral, usually through the seepage of water depositing the minerals within the mold. In time, the mold is filled and the materials deposited harden, creating a replica of the original fossil. This is called a cast fossil.
How are cast fossils formed?
An object that was repllaced by rock so the fossil is now 3D.
Would a fossil clam be classified as a mineral?
A fossil is not a mineral.
What are the six types of fossils?
The 6 types of fossils are called body fossils, trace fossils, molecular fossils, ressin fossils, microfossils, pseudofossils, and living fossils, and i dont have the information to describe them.
What are the steps necessary for a fossil cast to form?
Molds and casts are a third method of fossil preservation. Molds form after hard parts have been buried in mud, clay, or other material that turns to stone. Later, water dissolves the buried hard part, leaving only an impression or mold of the original. When this mold is filled with new material, a cast of the original is formed.
What are mold and cast fossils?
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.
What is cost fossil?
made when a mold is filled with sediments or minerals
When tiny spaces inside a fossil are filled in with minerals you have what kind of preservation?
Permineralization.
When an organism dies decays and leaves its shape in rock then rock is filled in with minerals that harden?
It's either Fossil or a Trace Fossil.
What is an exact copy of an original organism in which the hard parts have been penetrated and replaced by minerals?
A fossil.
Were fossil fuels formed from minerals under the earth's crust?
Fossil fuels are produced by the decomposition of animal and vegetable matter over time
A fossil made of hardened minerals in the solid shape of the original organism or one of its parts is called an?
cast
Are fossil fuels and minerals alike?
no minerals are not known to be fossil fuels
What is in the process in which minerals replace tissues?
In geology, petrification or petrification is the process by which organic material becomes a fossil through the replacement of the original material and the filling of the original pore spaces with minerals. So yeah the answer is petrification

Which fossil type could contain preserved parts of a organism?
It is called a mold fossil, which can become a cast fossil. After the soft parts of the animal rot away, a cavity remains (the mold fossil) which becomes filled with hardened sand or mud (the cast fossil).
