- What body parts do you most commonly find in fossils? Why?
- In which type of rock would you find a fossil? Igneous, sedimentary or metamorphic?
- How do the layers in Earth help us to figure out the age of fossils?
Fossils can be placed into four main groups based on the way they formed: impression, mineralised, trace and organic. This poster summarises the features of each group and can be used as a guide to classify fossils.
