Fossil Review & Quiz

Fossil Review and Quiz

Directions:

Since I am not here today, you will be completing your quiz differently. Throughout this lesson there are slides, pictures, and/or readings to help you answer the question along the way. You can use the back arrow at any time to go back to an informational slide or reading. You can also use your notes and discovery education to help you work through this assignment.

***This assignment will be graded off of correctness. You only have one chance (but it is open note) and will be your fossil quiz grade. Do your best work!

Basics of Fossils:

• Fossil- preserved remains or traces of living things and are  formed when living things die and are buried by sediments.

  • Only found in sedimentary rocks

  • Typically about 10,000 years old

• Two Main Types:

  • Body Fossils- a fossil of an organism's body or body part.

  • Trace Fossils- a fossil of an organism's footprints, burrows, or other features created by an organism's movement.

• Paleontologist – scientists who study, collect and classify fossils

Multiple Choice

Which is the best definition for the term fossil?

• an old rock

• the skeletons of animals

• the preserved remains or traces of an organism

• leaf imprints

Dropdown

Identify whether each example of a fossil is a body or trace fossil.

Multiple Choice

Typically, how long does it take for an organism to be turned into a fossil?

• at least 10,000 years

• 66 million years

• 4.5 billion years

• 100 years

Multiple Choice

Fossil are only found in _____________ rocks.

• Igneous

• Metamorphic

• Sedimentary

Multiple Choice

Which is the best explanation for why fossils are only found in the one type of rock (from slide 7)?

• The other types require too much heat and pressure which would destroy all the fossils

• The other types include weathering and erosion which would break up all the fossils

• The other types don't include enough heat which melts the fossil into place

Multiple Choice

What type of scientist studies fossils?

• Geologist

• Petrologist

• Paleontologist

• Dermatologist

Preservation Potential

Organisms are rarely turned into fossils because the conditions need to be just right. This includes:

1. Rapid (Fast) Burial

2. Gentle Burial

3. Burrowing Animals

4. Little Exposure to Oxygen

5. Burial in Organic (living things) matter

6. Hard parts of the Organism

The more of these contitions the better chance the organism will turn into a fossil.

Multiple Choice

Do all living things turn into fossils?

• yes

• no

Take a few minutes and review these main types of fossilization.

*Remember the key phrases to help you remember which is which.

Match

Match the type of fossilization to the description.

• Replacement

• Petrification

• Carbonization

• Permineralization

solid material from the organism dissolves and is replace with another mineral

Organic material is turned into stone. ex. petrified wood

Plants/animals decay except the carbon, leaving a carbon film on the rock

Groundwater carries dissolved minerals into the pores/cavities/holes of the organism

Drag and Drop

A​

​ is when the holes/cavities in the organism are filled with minerals, sand, clay etc. It is a solid copy of the shape of the organism.



Whereas, a ​

is when the hole/cavity is not filled in. It is a hollow area that shows the shape of the organism

The Fossil Record

Information gathered by paleontologists is called the fossil record which provides evidence of:

1. history of life on Earth

2. groups of organisms changing over long periods of time ​

3. Earth’s past climate ​

4. past environments and changes in Earth’s surface

The fossil record provides evidence to support the theory of evolution

• evolution – gradual change in living things over long periods of time ​

• scientific theory – well-test concept that explains a wide range of observations

• extinct – when an organism no longer exists and never will again ​​

Multiple Choice

What is the fossil record?

• Fossil information gathered and organized by palentologists

• The explanation for the scientific law of evolution

• the list of qualifications needed for something to be considered a fossil

​Directions:

Read the text to the right about what information fossils give

Open Ended

In complete sentences (3-5) explain how fossils can tell us about the past. Include evidence from the reading and the slide (#19). Go back to them for help!

Multiple Choice

What does it mean when an organism has gone extinct?

• when an organism no longer exists and never will again

• when an organism no longer exists but could re-evolve again

• when one organism changes into another one

Multiple Choice

Based on the last paragraph of the reading, what normally happens after a mass extinction?

Go back to the reading if you need to!

• Some of the organisms will re-evolve

• There is normally a period of quick growth of new species

• Lots of fossils are created more quickly
