200
They deteriorate before they can turn to fossils.
Why are the soft parts of most ocean organisms not preserved as fossils?
200
Shells, Fish, Trilobites, Teeth, Coral
Name two fossils you might find in an ancient ocean floor area.
200
Erosion
How are fossils exposed once they are covered by rock?

300
They both would have a backbone, tail, skeletal system, etc.
How would the fossils of two amphibians look similar?
300
Minerals have replaced the bone.
Why is a fossil dinosaur bone heavier than the original dinosaur bone?
300
The cast and the mold
When rock fossils are discovered, we often find two types of fossils (you made these in art). What do we call the two types?
300
There has always been water on Earth, the ocean changes in size and location, there has been ocean life in the past, etc.
Name two things we know about oceans from fossils.
300
Those areas were swamp like. Not so desert like!
If we find dinosaur tracks in a coal bed here in Utah, what does that tell us about the environment of Utah's past?
400
An organism dies, minerals deposit over organism/skeleton, pressure turns minerals to rock, erosion exposes the fossil.
Name the process of fossils forming around an organism on land. (We talked about this from the book)
400
Harder, Heavier, Different color, Slightly different shape, Modern animals may have evolved to look different than fossilized bone, etc.
Name two ways a fossilized lizard bone might look different than a bone that has not been fossilized yet.
400
Older ones are usually buried by more sediment, organisms have evolved (look different), early organisms were more simple, the oldest ones are generally heavier and harder.
Name two ways that early fossils (oldest) are different from more recent fossils.
400
Warm, Swampy, Damp, Vegetated
Name two characteristics of an area/climate where coal forms.
400
Competition, over-hunting, climate change, removal of resources, habitat destruction.
Name two things that might cause an organism to become extinct.
500
In Amber. (A kind of tree resin)
Name the place that organisms can be preserved as a whole animal.
500
It will have differences in weight, color, etc. It will also look like the remains of an ancient thing that is preserved.
How can you tell the difference between a fossil and and a recent bone or impression?
500
Sedimentary rocks are formed on the Earth's surface where organisms live and when an organism dies it becomes part of the Earth and sediments.
How do fossils form in Sedimentary Rock?
500
An organism that once lived in an ocean died and became part of the ocean floor, fossilized there and over time that area became mountains through continental drift.
How could a fossilized seashell be found at the top of the mountain?
500
In Millard County we find Trilobites fossilized in Limestone.
What specific evidence shows us that parts of Utah were covered by an ancient ocean?
