• The imprint or impression of a living thing
• Form after hard parts have been buried and then dissolved by water
Cast Fossils
Form when a mold is filled in with a mineral

Trace Fossils
Formed when an organism leaves an imprint and that imprint is filled with minerals or another substance like volcanic ash.

True Form Fossils
A fossil of the entire body of an organism
Formed when the organism’s tissues or hard parts did not decay

Body Fossils
Usually teeth and bones turned to stone
Minerals harden the bones or sometimes replace the actual bone itself and just make it a stone

Fossilization?
Sediment
Layers (minerals)
Movement
Erosion

Unaltered Preservation
Amber, tar, ice True form fossils!

Permineralization/ Petrification
Minerals seep in and replace the original tissues
Creates a rock-like fossil
Most dinosaur fossils are made from this! Body fossils!

Carbonization
The carbon inside the thing that died stays Carbon films!
