Mold Fossils

• 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

Carbon Films
Look like images or pictures!Created when every part of an organism
decays or dissolves except the carbon.

Trace Fossils
Formed when an organism leaves an imprint and that imprint is filled with minerals or another substance like volcanic ash.
Teeth marks, prints, nests, and more!

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

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

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