Fossil skeletons are usually crushed if other rock layers are above the ones they are in.

after layer Y was deposited.

d)

after layer Z was deposited.

5.

The illustration shows rock layers from three different locations and fossils the rock layers contain. The fossils are all trilobites, ancient organisms that were different over time. Which conclusion can be drawn from the information in the illustration?

The trilobite Remopleiridae is the oldest of all the trilobites.

d)

The trilobite Asaphidae appeared most recently of those shown here.

6.

When examining rock layers, you will find the oldest layers at the bottom. Newer minerals and rock are piled on top and, over time, this creates distinct rock layers. This is called _______.
