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

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
