What is the fossil record?
A history of life on earth recorded in rocks that allows us to look back in time in order to better understand how organisms and their environments have changed over time
The 4 step natural process of decay, which creates fossils
When an organism dies in a place where sediment can be laid down relatively quickly or buried rapidly
The long dead remains of that have escaped decay and have become part of the Earth's crust
What is the first step of Fossilization?
Fossilization best occurs when an organism dies in a place where sediment (dirt or debri) can be laid down relatively quickly. This is often an aquatic environment (ex: estuary), but it can be caused by a rapid burial (ex: landslide or volcanic ash).
After death, the flesh may decay or be scavenged, but hard materials, usually bones and teeth, are able to remain long enough for burial.
After burial, the bones are subjected to pressure. Minerals in the surrounding sediments move into the bones and replace the minerals in them.
Erosion of the sediments exposes the fossils on the surface.
What is the second step of Fossilization?

What is the third step of Fossilization?
Fossilization best occurs when an organism dies in a place where sediment (dirt or debri) can be laid down relatively quickly. This is often an aquatic environment (ex: estuary), but it can be caused by a rapid burial (ex: landslide or volcanic ash).

After burial, the bones are subjected to pressure. Minerals in the surrounding sediments move into the bones and replace the minerals in them.
Erosion of the sediments exposes the fossils on the surface.
What is the last step of Fossilization?
Fossilization best occurs when an organism dies in a place where sediment (dirt or debri) can be laid down relatively quickly. This is often an aquatic environment (ex: estuary), but it can be caused by a rapid burial (ex: landslide or volcanic ash).

Erosion of the sediments exposes the fossils on the surface.
What is not a fossil?
The preserved remains of the organism itself (ex: Tyrannosaurus rex)
The impression of an organism in the sediment (ex: a mold and compression-impression fossils)
The marks made by the organism during its lifetime (ex: trace fossils)
Soft materials such as the cartilaginous skeletons of sharks

How does a Table Mountain form?
Table mountains form when an area of hard material covers part of a larger area of softer ground. The covered softer ground then erodes away and leaves a flat topped mountain.
Table mountains form when an area of soft material covers part of a larger area of harder ground. The covered hardened ground then erodes away and leaves a flat topped mountain.
