History of Earth

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 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.

Fossils of trees were discovered in a sedimentary rock layer, and in a rock layer below were fossils of clams. Based on this evidence, what conclusion can be made about the sequence of climates in the past in the area where the fossils were discovered?

• Based on the evidence, it can be assumed that this area was an underwater forest.

• Based on the evidence, it can be assumed that this area was a forest before it was a beach or ocean.

• Based on the evidence, it can be assumed that this area was an ocean or beach before it was a forest.
