The fossil record holds important
But not everything that once lived gets
All of the fossils that exist, whether dug up or still in the earth, provide what?
Definition of a Fossil Record
What is a Paleontologist?
Fossils can be
What are some examples of those parts that can be left behind as fossils? (List 4)
1)
2)
3)
4)
Fossils can also be
What are some examples of those traces that can be left behind as fossils? (List 4)
1)
2)

It possible for a fossil to be both a trace fossil and body fossil.
What is a body fossil?
What is a trace fossil?
Most fossils are formed when
Layers of sediment, such as
Eventually, the layers may
Why is burial important speed important with fossils?
What is a scavenger?
What is a decomposer?
What are physical factors?
Which organism do you think is most likely to be preserved.
If an organism or its trace gets buried
If a trace or body part/organism gets buried is it 100% guaranteed that it will fossilize?
Why or why not?
What are molds?
What are mineralizations?
What are impressions?
What are microfossils?
In each of these examples, the organism was buried in sediment. But does an organism have to be buried in sediment to become a fossil?
Why or why not.
Explain how an organism can be preserved in ice.
Explain how an organism can be preserved in amber.
What is amber?
Explain how an organism can be preserved in tar.
Which do you think is more likely to fossilize?
Explain your reasoning for the above answer.
What substance best helps soft structures remain preserved?
How does the Benthic Ocean environment affect fossilization?
How does the Lake environment affect fossilization?
How does the Rocky Intertidal environment affect fossilization?
How does the Rainforest environment affect fossilization?
You just learned that not all organisms have an equal chance of fossilizing. What are the important factors to consider?
Why is the above answer the correct answer?
Why is the fossil record not complete?
1) All
2) Only some
3) Of those that remain.
Of all the organisms alive today, what percent do you think will eventually become fossils?
Remember
Insects
On the other hand,
How can fossils get crushed?
How can fossils get melted?
How can fossils get moved?
How can fossils get eroded?
Igneous rocks are...
Sedimentary rocks are...
Metamorphic rocks are...
Which type of rock is most likely to contain fossils?
Take a look at this geologic map of Montana. The different colors represent the rocks we can see at the surface, both by age and by type.
Imagine that you are a paleontologist in search of Tyrannosaurus rex.
Where would you start looking
What is the uplift process?
What is the erosion process?
Where do paleontologists look for fossils because the location has, like similar areas, are places where uplift and erosion occur.
Why don’t paleontologists always find fossils in the areas likely to contain fossils?
How do fossils represent only a partial picture of life in the past?
1) Organisms
2) Only
3) Of those that remain,
4) Some fossils
5) Of those fossils that do exist,
Fossils are:
Which would most likley to fossilize
Why is a mammoth more likely to fossilize than a caterpillar?
Rapid burial is important in the fossilization process because:
Fossils are more likely to be found in...
Few organisms ever become fossils because:
BONUS: (and be careful; this one is a bit tricky!) Of the tiny percentage of organisms that ever become fossils, most are never found because:
Why was the above the correct answer?
