Which of the following is MOST likely to become a fossil that is preserved on Earth?
A jellyfish preserved in lava (Ha! Gotta laugh at this one)
A shark tooth preserved in mud that becomes shale
A land mammal that dies on land in mud that eventually becomes mud
A polar bear who dies and is frozen in glacial ice
Fossil remains are most likely to be found in which type of rock?
The organisms never die, they live forever
The organism died and was buried at the same time the sediment was accumulating only later to become rock.

In which layer did fossil C come into existence? How do you know this?
Layer 1-Because that is the layer it is first seen
Layer 1- Because that is the last layer it is seen in
Layer 2- Because that is the layer it is first seen
Layer 2- Because that is the last layer it is seen in
Fossil A is an ancient mollusk, an organism that needs water to survive. Why do you think that the mollusk went extinct in this particular sample of the fossil record?
When the ocean levels rose in layer 4, the mollusk went extinct because they cannot live in water
For some reason, the ocean disappeared causing the mollusk to thrive
For some reason, the ocean disappeared causing the mollusk to go extinct
When the ocean level rose in layer 4, the mollusk thrived because they need water
What are the oldest fossils and why?
B, C- because they are closest to the top
A, B- because they are closest to the bottom
They are all the same age- because they are all found on layer 2
A, B- because they are found closest to the top
Why are similar fossils found all over the world?
The animals swam to new parts of the world before going extinct
The land masses were once connected
The organisms were transported to different areas of the world
They are not similar fossils.
Which organism went extinct before gastropods evolved?
Trilobite
Crinoid
Fern
Ammonite
