How many different ways can fossils form?

When most people think of fossils they think of dinosaur skeletons and large bones, but there are many different types of fossils to be found. Palaeontologists, people who study fossils, divide them into two major types - body fossils and trace fossils. Body fossils show us what a plant or animal looked like. 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. Petrified wood, frozen mammoths, and insects in amber are all body fossils. The second type of fossil records the activity of an animal. Known as trace fossils, these include footprints, trackways, and coprolites (fossil poo!). Footprints and coprolite are trace fossils - they show us how an animal lived.


Fossils would include skeletons shells seeds tracks all of these?

These are known as trace fossils. Trace fossils are more technically known as ichnofossils.Footprints are more correctly described as repichnia, burrows as domichnia and fossilised dung or dropings are known as coprolites.Please see the related links for more information.the answer is trace fossils.

What are the difference types of fossils?

Mold fossils- an empty space is left when an organism is buried in sedimentary and it decays.Cast fossils- Minerals in rocks fill space left by a decayed organism.(replica)Trace fossils- Markings left by an animal. (footprints, trail, or burrow)Petrified fossils- Minerals penetrate and replace all or part of an organism.Imprint fossils
