Fossils

By:Emma H

What are fossils?

The remains or impression of a prehistoric organism preserved in petrified form as a mold form or a cast in rock.

What type of rock are fossils found in?

Fossils are most commonly found in sedimentary rock,but all sedimentary rocks are not necessarily fossiliferous.

How are they formed?

Fossils are formed when a plant or animal dies and is buried in mud and silt.

Examples of how they are formed

Freezing is a way you can form a fossil.This happens rarely because the animal has to continually freeze from the time of death until the time it gets discovered.
