Fossils are made when a living thing dies and is buried by mud, silt, volcanic ash, or sand. Fossils could also be frozen in ice, mummified in hot or cold deserts, or preserved in tar. Usually, all of a living thing's soft parts decay, leaving only the hard parts to be buried, except when a living thing is frozen or mummified. The mud, silt, and sand are called sediments.
The sediments have water with minerals in it. The minerals in the water soak into the hard parts, changing them into a rock like material and preserving the hard parts as fossils.
One kind of fossilization is called replacement, where the minerals have replaced, molecule by molecule, the hard parts of the remains.
Permineralization is another kind of fossilization. Permineralization happens when the minerals have only filled in the spaces of the hard parts of the remains.
Living things which die in or near oceans, lakes, or rivers have a better chance of fossilization than those which die on dry land, because they will be quickly buried. Over thousands and millions of years the sediments form heavy layers which slowly turn into sedimentary rock.

What was the natural history museum made of?
I have visited one in Nicobars Island. Its made from fossils of plants/animals remains on the stones, It also has stuffed animal remains and sea creatures for display.
Is limestone a fossil fuel?
Limestone is not a fossil fuel because it is not made from the carbon-containing soft tissues of long dead plants and animals. It is formed by fossils based on animal shells. Limestone is not used as a fuel but is used by industries for other purposes.
Amber fossils is made out of?
Resins from plants and trees that gets trapped & preserved in the soil and eventually gets hardened over a long period of time.
What are the most common types of fossils found in Florida?
The most common four types of fossils are:mold fossils(a fossilized impression made in the substrate - a negative image of the organism)cast fossils(formed when a mold is filled in)trace fossils = ichnofossils(fossilized nests, gastroliths, burrows, footprints, etc.)true form fossils(fossils of the actual animal or animal part).
Define fossils and explain how fossil are made?
Fossils are depositions of dead animal imprints and/or bones. When an animal or plant dies, its skin rots away, leaving behind the bone or imprint.
Describe what fossils are and list three different kinds?
Fosssils are the preserved remains or traces of animals , plants, and other organisms from the remote past. The totality of fossils, both discovered and undiscovered, and their placement in fossiliferous (fossil-containing) rock formations and sedimentary layers (strata) is known as the fossil record.Types:-mold fossils (a fossilized impression made in the substrate - a negative image of the organism)cast fossils (formed when a mold is filled in)trace fossils = ichnofossils (fossilized nests, gastroliths, burrows, footprints, etc.)true form fossils (fossils of the actual animal or animal part).
How are fossils and artifacts different?
Fossils are the remains of dinosaurs, prehistoric plants and other prehistoric creatures which lived millions of years ago. Artifacts are items that were made by intelligent homonids or by ourselves (homo sapiens) in the past not so long ago.
What is the definition for fossils?
Fossils are what's left of ancient plants and animals. They are imprints in rock, generally sedimentary rock. The word "fossil"means "dug up" and it comes from Latin. Fossil fuels were made in the earth and took a long time to make.
How fossils are made?
Fossils are made by the body of a plant or an animal, insect or other living being that has been trapped on or in a rock. Over hundreds, thousands, or millions of years, the organism disintegrates and is replaced by minerals.
What is bio fuel made of?
plants and animal
