- The Paleozoic Era has 6 different periods: "Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian" (Fernando Herrera). - Pangea occured during this era. Before pangea took place, the contients were far and separate. After pangea, the continents came together forming one big continent (Fernando Herrera). - During this era the amount of invertabrates increased signifcantly (Paleozoic era). - Most of the artifacts during the paleozoic era do not exist due to erosion (Paleozoic era). - Due to dry and warmer climate by the late permian, this caused an increase in reptiles (Paleozoic era).
Fun Facts:
Permian Triassic Extinction Event: when almost all of the marine species were extinct and 30% of the land species survived (“Eons”). Great Ordovician Extinction Event: an extinction event that scientists do not know what caused the extinction. A possibility is that the extinction was caused from an increased amount of oxygen in the atmosphere (“Eons”).

During the Paleozoic era, sea levels started to rise causing another boost of oxygen to happen. This made living more suitable for different types of organisms. Later, because so many plants began to grow due to the increase in oxygen, this created an ice age. After the ice age, the earth recovered and started to have a warm climate during the Silurian period (“Eons”).
