Making the world better, one answer at a time. The climate at the beginning of the Paleozoic era was moderate, but managed to stabilize during the mid-era. At the end of the era, the levels of oxygen in the atmosphere increased and carbon dioxide levels decreased.
The layers of the fossil record are divided into three main eras: Paleozoic, Mesozoic, and Cenozoic. These eras are characterized by different kinds of fossils.The Paleozoic era is known for marine life, amphibians, and reptiles.he type of fossil found in the various layers changes as one goes up the geological column, from invertebrates, fish, amphibians, and reptiles, to the mammals and birds in the upper layers. This order in the fossil record is one of the prime evidences used by scientists to establish evolution as a fact.
