Natural gas is a fossil fuel consisting largely of methane (CH4).

A pyogenic liver abscess forms pockets of pus in the liver.
A coal-like residue, bulids up and forms around something to form a fossil. This fossil should be classified as a carbon-film fossil.
They are formed in the fractional distillation of fossil fuels. They are made up of carbon and hydrogen atoms, and thus can range from small molecules such as methane (CH4) or octane (C8H18) to large macromolecules.

Methane
The natural gas fossil fuel was formed 300 million years ago, but it didn't take that long to become.Natural gas is methane, and you can make it yourself in your lower bowel in a couple of days. Anywhere organic material (plants, for example) decompose without oxygen, methane is produced.
When a fossil mold is filled, it forms a fossil cast. The cast is a replica of the original organism or object that created the mold, made of the same material as the original organism or object. Fossil casts are valuable in paleontology for studying the morphology of ancient organisms.
The fossils of the oldest life forms can be found in the Precambrian period of the fossil record.
Yes, natural gas, which is mostly methane, is a fossil fuel. It is made from dead animals and plants which were compressed and heated under the ground hundreds of millions of years ago. It is called a fossil fuel because it comes from the fossilised remains of the organic plants and animals. Natural gas holds all the carbon from those organisms and the carbon is released when the gas is burnt.
