Organisms D and C clearly lived in an aquatic (water) environment. Organism A does not look like it lived in the water. What is the most likely explanation for this?

• The fossil in layer A died on land and was carried to the water

• The fossils in layer C and D did not live in the same location as the fossil in layer A

• The environment changed over a long period of time. It used to be under water, but is not anymore

Why do you think there are not fossil for every organism that has every lived?

• Many organisms are too large to form fossils
