molds and casts, trace fossils, petrified wood, and carbon film
The 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 several types of fossils, including:
There are five diffferent means of preservation that create fossils. They are:
1. Permineralization
2. Casts and molds
3. Replacement and recrystallization
4. caronization
5. Original material
Palaeontologists, people who study fossils, divide them into two major types - body fossils and trace fossils.
The first type, body fossils, are the fossilised remains of an animal or plant, like bones, shells and leaves. These can be mould and cast fossils, like most of the fossilised dinosaur skeletons and big bones we see, replacement fossils, like petrified wood, or whole body fossils - mammoths caught in ice, or insects trapped in amber.
The second type of fossil records the activity of an animal. Known as trace fossils, these include footprints, trackways, and coprolites (fossil poo!).
Fossils can be put into two categories; fossilized body parts, and ichnofossils (fossilized traces). The types of fossils are mold, cast, trace and true form.

Some types of evidence of ancient life that can be preserved as fossils include bones, teeth, shells, footprints or trackways, and imprints of soft tissues. Plant material such as leaves, wood, and pollen can also be fossilized.
the type of sedimentary rock determines when other layers in rocks formed and how they shifted. the properties of the species of time periods need certain environmental conditions. these conditions must be what types of environments ancient creatures lived in.
Igneous rocks and most metamorphic rocks, of an igneous origin.
By comparing fossils in higher sedimentary layers with fossils in lower sedimentary layers, scientists can learn about the relative ages of the fossils. This helps in understanding the sequence of events in Earth's history and the evolutionary relationships between different species.
