Fossilization
Learning objectives
- To illustrate the basic processes involved in the fossilization process.
- To become aware of the vastness of the Geological Time Scale.
This animation shows the fossilization by permineralization of a living organism (the example used is a trilobite). The time scale is consistent with the dimensions of the principle stages in the transformation of a fossil to rock.
- Decomposition of organic (soft) parts
- Burial of the carapace (exoskeleton) by sediments
- Permineralization of the exoskeleton
- Geological processes
- Erosion bringing the buried fossil to the surface
