Fossils are the remains or traces of organisms from the past. These are found world-wide, and come in various forms. Teeth and bones are some of the most common fossils, as they are hard substances, whereas soft-bodied species such as Jellyfish are rare as fossils, as their bodies break done.

What is a Fossil?Edit

For something to be classed as a fossil, it has to be at least 10,000 years old, though can be in the form of the actual fossil, trace fossils, casts, or moulds.

It's not just animals though, any living organism can be found as a fossil.

Different Forms of FossilsEdit

Petrification - This is when the organic material is converted into a rock or fossil.

Freezing - This is when an organism becomes frozen, which can lead to perfect preservation of a specimen. Some examples include mammoths which have been frozen so well that people from the area eat the meat.

Mummification - This is when an organism which has died in a dry landscape has had all of the water in it's body dried out. This often leads to a well preserved specimen.

Tar- Tar pits often preserve species in extreme quality, and often contain many fossils in.

Carbonization - This is when an organism decays, but leaves behind carbon. A common example is wood.

Amber - This is when resin from a tree covers an organism, and preserves them for millions of year. This is hw most insects are found, but also species as large as frogs and geckos.

Coprolites - This is the fossilized remains of dung.

Trace Fossils - Fossils which were never organisms, but were made by one. For example footprints and burrows.
