Fossil Formation Clues to the Past Science Court Study of Dinosaurs

A preserved clue to life on Earth long ago is called… Fossil Formation What is a fossil?

When scientists find a fossil, they make a about the animal while it was alive. Clues to the Past What is a prediction (or an inference?

True or False: Only animals can become fossils. Science Court False

A scientist who studies the remains of living organisms from long ago is called what? Study of Dinosaurs A paleontologist

Fossils are formed in these types of rocks. Fossil Formation What are sedimentary rocks?

Give at least one reason why fossils are important. Clues to the Past 1)They tell us what living things were like in the past. 2) They also tell us what Earth was like long ago.

What is petrification? Science Court Petrification is the name for the Process that turns living things, Like bones, into rock.

Scientists know about how old A fossil is by looking at where it was in the of the Earth. Study of Dinosaurs What are the layers of the Earth?

Tracks, burrows, and animal droppings are examples of this type of fossil. Fossil Formation What are trace fossils?

How can whole plants and animals be preserved as fossils? Clues to the Past If animals were trapped in tar pits, Glaciers, or tree sap, they are preserved as whole fossils.

Name the 4 steps required to petrify an organism. Science Court 1.The animal dies 2.It gets buried quickly under sediment 3.The tissue decays 4.The bones are slowly replaced by minerals.

Which layer is older in this picture, the yellow layer or the blue layer? Study of Dinosaurs The yellow layer

An imprint made by the outside of a dead plant or animal is called a. Fossil Formation What is a mold fossil?

Explain how scientists know that living things have changed over time. Clues to the Past Scientists compare fossils found to living animals today, so that shows how they have changed over time.

The soft parts of animals include things like skin, tongues, and organs. Why do we not usually find fossils of the soft parts of animals? Science Court The soft parts decay before they can become fossils.

Name at least one way Paleontologists predict the ages of fossils they find. Study of Dinosaurs 1)Looking at where the fossil was Found in the layers of rock.2) Look at how much of certain particles have decayed over time. The more particles that have decayed, the older the layer of rocks where the fossil was found.

When sediments or minerals fill a mold fossil, this type of fossil is formed. Fossil Formation What is a cast fossil?

When minerals have replaced Once living material, this is said To have been. Clues to the Past What is petrified?

Name two things that work to Change the surface of the Earth. (Answer in the form of a question.) Science Court Earthquakes, volcanoes, shifting continents, and erosion (water and soil erosion)

How can scientists look at fossils and make predictions about how the organism lived? Study of Dinosaurs Scientists can examine the fossils of organisms to see what made it possible for them to survive in that habitat.

How many points do you wager?

What did the habitat of Kentucky Use to be like? How do we know? (Think about the types of fossils We have looked at throughout our unit.) Final Jeopardy Question Kentucky used to be under water a long time ago. We know this because we have found a lot of shells in the sedimentary Rocks Seen in class. Since animals with shells live underwater, we know that Kentucky used to be underwater as well.

Thanks for playing Jeopardy!! See you next time!
