things that died long ago

What scientists
study fossils?
Page 6
What can we learn
from studying fossils?
Page 7
We can learn about the kinds of plants and
animals that used to live on Earth…as well
as what kinds of things animals ate.
Page 8
What are the 3 types of fossils?
Page 10
Which fossil is the shape of a once-
living thing left in a sediment when rock
formed?
Page 12
Which fossil forms when mud or
minerals later fill a mold. This has the actual shape of the living thing-without being a real piece of
the living thing.
Page 14
If a fossilized tooth of a dinosaur is sharp, what do
scientists predict it ate? Plants or
Meat???
Page 16
Why are plant fossils not as common as
animal ones?
Page 17
Because plants are a lot more fragile and don’t usually
survive the process of becoming a fossil
Page 18
Why are more fossils found in
sedimentary rocks than in
others?
Page 19
Because the sediment covers the fossil over
time. Heat and pressure from
metamorphic and igneous rock often
destroy any animal or plant remains
Page 20
Are the fossils found on the
very bottom of a layer of rock
older or newer than other
layers?
Page 21
OLDER. They started out a long time ago
and were covered by
newer ones on top
Page 22
How are footprint fossils different than bone fossils?
Page 23
Footprint fossils are cast fossils.
They are the shape or imprint of an animal or
plant.
Page 24
Bone fossils are mold fossils. They are an
actual piece of the living thing.
Page 25
Which of these is not a fossil? Why?A. a cast of a seashellB. A footprint of a dinosaurC. A chunk of petrified woodD. a bone of an elephant
Page 26
An elephant bone…because elephants are not extinct.
Page 27
What might scientists learn from a fern fossil?
A: what color the fern wasB: which animals ate the
fernC: How ferns have
changedD: which other plants lived
at the same time
Page 28
How ferns have changed
Page 29
What can you infer about a place that has
fish fossils?
Page 30
That place was once under
water (sea).
Page 31
What can a footprint tell you about the animal
that made it?
Page 32
The animal’s size
