1. Fossils A fossil is the preserved remains or traces of living things They must be natural and ancient (10,000 years or older) and buried in rocks

2. Fossils where the spaces inside are filled with minerals from groundwater (turned to stone) Examples: bones or wood Mineral Replacement/Petrified

3. Carbon Films A thin film of carbon residue left behind when pressure forces gases and liquids from an organism (photocopy of a organism) Examples: Graptolites coal

4. Molds A cavity or hollow space left in a rock when the hard parts of an organism have decayed or dissolved in water or air. Examples: Seashells Muffin pan

5. Casts A copy of an original object formed when minerals fill a mold and make a new rock Examples: Seashell Muffins

6. Original or Preserved Remains Fossils where the original soft parts (skin, hair) of an organism have been preserved by either ice, amber or tar Examples: Insects Wooly mammoth Tar pits

7. Tar Pits Animals were believed to have been stuck in tar areas. The tar then seeped into their bones and over time formed a fossil.

8. Trace Fossils Fossils that show the activities of an organism (trails and burrows, tracks, poop) Examples: Worm burrows Sauropod tracks

9. Fossils- Ticket to Leave 1. Name the 6 types of fossils. 2. Cavity or hollow area 3. Activities of organism (tracks, trails, poop)

10. 4. What type of fossil is shown in the picture? 5. A fossil that is in the shape of the organism.

11. 6.Wood that is “turned to stone” or replaced by minerals 7.“Photocopy of an organism” or thin copy caused by pressure 8.What information can a fossil tell about the past? List two examples.
