8th Grade Fossil Assessment LS4-1

First & Last Name

1. What type of rock are fossils found in?

• Metamorphic
• Igneous
• Sedimentary

2. What are the four types of fossils?

• trace, hard, soft, shells
• mold, trace, true form, and cast
• mold, true form, false form, bones

3. The part of the animal that can form a fossil is

• Hard parts, like teeth and bones
• Soft parts like stomach and blood
• The brain
• Only the bones

4. What is a true form fossil?

• A fossil that is made from a footprint
• A fossil made from the actual organism itself
• A fossilized impression
• A filled-in version of a fossilized impression

5. Fossilized nests, burrows, feces and footprints are what type of fossil?

• Mold Fossil
• Cast Fossil

6. Fossil data tells us that

• Organisms lived long ago that do not live now
• The land has changed over time
• Some dinosaurs lived in groups
• Some areas that are now land, were once under the ocean
• All of the above

7. How long does it take fossils to form?

• Days
• About 10 years
• Thousands of years
• Millions of years

8. What is the Law of Superposition?

• The larger the layer the older it is
• Older layers are at the top
• The layer on the bottom is the oldest
• Igneous rocks are always older than sedimentary rocks

9. What is an index fossil?

• Index fossils are fossils that are found in the rock layers of only one geologic age
• Index fossils are fossils that are of living fossils
• Index fossils are whole body fossils of animals caught in amber
• Index fossils show up in every layer from all time periods
