The illustration below 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 Cyclopygidae appeared most recently of those shown here.

• The trilobite Ceratopigidae appeared before all the others.

• The trilobite Remopleiridae is the oldest of all the trilobites.

• The trilobite Asaphidae appeared most recently of those shown here.

The illustration below shows three rock layers and an intrusion of basalt. When molten rock pushes its way into rock layers already formed, it creates an intrusion. The rock strata indicate that the basaltic intrusion must have occurred ___.

• after the limestone was deposited

• before the granite formed

• before the limestone was deposited

• before all three layers were formed

The fossil remains of organisms with skeletons are not found in the lowest layers of rock discovered. How is the lack of fossilized skeletons in the lowest rock layers best explained?

• Organisms with skeletons did not evolve until after these rock layers formed.

• The fossils of organisms with skeletons are only found in the oldest rocks.

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

• Organisms with skeletons live only at the highest altitudes, which is where they turn to fossils.
