Fossil Formation
A preserved clue to life on
Earth long ago is called…
What is a fossil?
Clues to the Past
When scientists find a fossil, they
make a
about the
animal while it was alive.
What is a prediction
(or an inference?
Science Court
True or False: Only animals can
become fossils.
False
Study of Dinosaurs
A scientist who studies the
remains of living organisms
from long ago is called what?
A paleontologist
Fossil Formation
Fossils are formed in these
types of rocks.
What are sedimentary rocks?
Clues to the Past
Give at least one reason why
fossils are important.
1) They tell us what living things
were like in the past.
2) They also tell us what Earth
was like long ago.
Science Court
What is petrification?
Petrification is the name for the
Process that turns living things,
Like bones, into rock.
Study of Dinosaurs
Scientists know about how old
A fossil is by looking at where
it was in the
of the
Earth.
What are the layers of the Earth?
Fossil Formation
Tracks, burrows, and animal
droppings are examples of this
type of fossil.
What are trace fossils?
Clues to the Past
How can whole plants and
animals be preserved as fossils?
If animals were trapped in tar pits,
Glaciers, or tree sap, they are
preserved as whole fossils.
Science Court
Name the 4 steps required to
petrify an organism.
1.The animal dies 2.It gets buried
quickly under sediment 3.The tissue
decays 4.The bones are slowly
replaced by minerals.
Study of Dinosaurs
Which layer is older in this picture,
the yellow layer or the blue layer?
The yellow layer
Fossil Formation
An imprint made by the outside
of a dead plant or animal is
called a
.
What is a mold fossil?
Clues to the Past
Explain how scientists know that
living things have changed over
time.
Scientists compare fossils found to
living animals today, so that shows
how they have changed over time.
Science Court
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?
The soft parts decay before
they can become fossils.
Study of Dinosaurs
Name at least one way
Paleontologists predict the ages
of
fossils
they
find.
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.
Fossil Formation
When sediments or minerals fill
a mold fossil, this type of fossil
is formed.
What is a cast fossil?
Clues to the Past
When minerals have replaced
Once living material, this is said
To have been
.
What is petrified?
Science Court
Name two things that work to
Change the surface of the Earth.
(Answer in the form of a
question.)
Earthquakes, volcanoes,
shifting continents, and
erosion (water and soil erosion)
Study of Dinosaurs
How can scientists look at fossils
and make predictions about how
the organism lived?
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?
Final Jeopardy Question
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.)
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!
