In which type of rock would most fossils be found?
Sedimentary

How is the fossilized skeleton of a dinosaur similar to the
modern skeleton of a lizard?
They have backbones and tails.

Erin brought a piece of sandstone to school that had some ripples across it. What
might it be a fossil of?
Wave marks

Why is a fossil dinosaur bone much heavier than the original
bone?
It is now made of minerals
![Page 6: Fossil and Soil Review Fossils #1Fossils #2Fossils #3Fossils and SoilSoil 10 20 30 40 50.](https://reader035.fdocuments.us/reader035/viewer/2022062500/5697bfa51a28abf838c97927/html5/thumbnails/6.jpg)
What are the three types of fossils?
Impression, mineral replacement, trace

The soft tissues rot away.
Why are the soft tissues of an animal’s or an organism’s body
not usually preserved as a fossil?
![Page 8: Fossil and Soil Review Fossils #1Fossils #2Fossils #3Fossils and SoilSoil 10 20 30 40 50.](https://reader035.fdocuments.us/reader035/viewer/2022062500/5697bfa51a28abf838c97927/html5/thumbnails/8.jpg)
Because we find fossils of them.
How do we know that different kinds of plants and animals
lived in Utah millions of years ago?

Oceans have changed in size and
location
What have scientists learned about oceans by studying
fossils?
![Page 10: Fossil and Soil Review Fossils #1Fossils #2Fossils #3Fossils and SoilSoil 10 20 30 40 50.](https://reader035.fdocuments.us/reader035/viewer/2022062500/5697bfa51a28abf838c97927/html5/thumbnails/10.jpg)
The mountain was once part of an ocean
bottom
What might a scientist tell from seashell fossils found on top of
a mountain?
![Page 11: Fossil and Soil Review Fossils #1Fossils #2Fossils #3Fossils and SoilSoil 10 20 30 40 50.](https://reader035.fdocuments.us/reader035/viewer/2022062500/5697bfa51a28abf838c97927/html5/thumbnails/11.jpg)
Plants, shells…
What other types of fossils might you expect to find with a
dinosaur fossil?
![Page 12: Fossil and Soil Review Fossils #1Fossils #2Fossils #3Fossils and SoilSoil 10 20 30 40 50.](https://reader035.fdocuments.us/reader035/viewer/2022062500/5697bfa51a28abf838c97927/html5/thumbnails/12.jpg)
Fossils of water creatures where there
is no water today.
What evidence is there that parts of Utah were once the
sea floor of an ancient ocean?
![Page 13: Fossil and Soil Review Fossils #1Fossils #2Fossils #3Fossils and SoilSoil 10 20 30 40 50.](https://reader035.fdocuments.us/reader035/viewer/2022062500/5697bfa51a28abf838c97927/html5/thumbnails/13.jpg)
Mammoth, trilobite…
Name an animal that used to live in Utah but is now extinct?
![Page 14: Fossil and Soil Review Fossils #1Fossils #2Fossils #3Fossils and SoilSoil 10 20 30 40 50.](https://reader035.fdocuments.us/reader035/viewer/2022062500/5697bfa51a28abf838c97927/html5/thumbnails/14.jpg)
Plants lived in the area before there were
dinosaurs
Ryan was studying a fossil layer model. He noticed that there were
plant fossils in the lower levels, but no dinosaur fossil. What could this mean?
![Page 15: Fossil and Soil Review Fossils #1Fossils #2Fossils #3Fossils and SoilSoil 10 20 30 40 50.](https://reader035.fdocuments.us/reader035/viewer/2022062500/5697bfa51a28abf838c97927/html5/thumbnails/15.jpg)
What are minerals that have taken the place of the bone?
Fossil bones are much heavier than the original bone because of this.
![Page 16: Fossil and Soil Review Fossils #1Fossils #2Fossils #3Fossils and SoilSoil 10 20 30 40 50.](https://reader035.fdocuments.us/reader035/viewer/2022062500/5697bfa51a28abf838c97927/html5/thumbnails/16.jpg)
What is prehistoric?
The period of time before history was recorded.

What is a trilobite?
This extinct ocean shellfish shows that parts of Utah were once the sea floor
of an ancient ocean.

What is sedimentary rock?
The best rock for finding fossils.

What is subsoil?
The layer of soil below the topsoil that has larger grains of rocks and minerals
and is usually lighter in color.
![Page 20: Fossil and Soil Review Fossils #1Fossils #2Fossils #3Fossils and SoilSoil 10 20 30 40 50.](https://reader035.fdocuments.us/reader035/viewer/2022062500/5697bfa51a28abf838c97927/html5/thumbnails/20.jpg)
Downward

What are fossils?
These are the record keepers of the Earth. They show us how life has
changed.

Sally dug up some soil, put it in a cup, and weighed it. She put it in a warm place with no cover on the cup. Two weeks later she
weighed it again. It weighed less than the first time. Why?
Water in the soil had evaporated.
