From this figure and your knowledge of geological time scales, we can infer that:

1.Fossils found at point A are similar to those found at point B.
2.The rock formations of region B are much more recent than those of region C.
3.The rock layers and life forms found within are older as you move from layer D to layer A.
4.There are no generalizations to make. You have to carbon date everything regardless of what layer the fossil is found in.
