Usually the remains of dead plants and animals quickly decay and are
destroyed. When the remains are protected from scavengers and
micro-organisms, however, they can become fossilized.
If a carcass is in water and sinks to the bottom, the body can be
buried by sediment. Soft parts, such as skin, muscle, or organs decay
rapidly and are rarely found as fossils. The hard parts (bones, shells,
or teeth) may be altered to become fossilized remains. When water
penetrates the bones of a dead animal, the water dissolves the calcium
carbonate in the bones. A deposit of another very hard mineral, silica
(quartz) remains, turning the bones into a petrified (rock-like) substance.
When an organism is buried under many layers of sediment,
pressure and heat may build up, leaving a thin film of carbon residue
on rock surfaces. The residue forms an outline of the organism. The
outline is called a carbonaceous film.
Five different types of fossils are fossil fuels, imprint fossils, cast fossils, petrified wood, and actual remains. Imprint fossils happen when a leaf, feather, or bone leaves an imprint on sediment and it becomes hardened. Cast fossils happen when minerals fill in the hollow of an animal track or shell.
mold - hollow impression of a living thing in rock after it cast
solid - mineral deposit that filled a mold, leaving a copy of the living thing
imprint - an impression in rock made by a living thing during its life activities
petrification - plant or animal tissue replaced by minerals
whole animal - an entire plant or animal encased and preserved in ice, sap, or another material
I'm assuming you mean: the 6 types of fossils are:
1. mold
2. cast
3. trace
4. petrified wood
5. carbon film
6. amber
molds and casts, trace fossils, petrified wood, and carbon film
Trace Fossil, Mold, Cast and Index Fossil :p
1. Prints! 2. Changed hard parts!
3. Molds! 4. Casts!
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).

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.
The two types are Dna, and fossils
Fossils that are the most useful for correlation tend to be found in various types of rocks, are widespread, and easy to recognize. One rock type where fossils are found is sedimentary rocks.
describe and tell the four types of tourist?
you can get all the fossils for every game once you have beat the elite four

There are four types of fossils that can be found. These are true fossils, mold fossils, trace fossils and cast fossils.
molds and casts, trace fossils, petrified wood, and carbon filmThe four types of fossils are mold fossils, cast fossils, true-form fossils, and trace fossils. Mold fossils are impressions from when the plant or animal first decomposed. Cast fossils are plant or animal remains. True-form fossils are remaining body parts from an animal. Trace fossils are marks that have been left by animal, such as footprints.

There are a variety of types of fossils. These include cast fossils, mold fossils, petrified wood, as well as fossil fuels.
There are four main types of tourists. These types of tourists include international tourists, regional tourists, domestic tourists, as well as excursionists.
