The Paleozoic Era
The Paleozoic Era is the Era after Precambrian Time.The Paleozoic Era began 542 million years ago and ended 251 million years ago. The Paleozoic Era’s nicknames are “The Explosion of Life” and “The Age of Invertebrates”. The Paleozoic Era was split into 6 different periods, they are in order, the Cambrian, Ordovician, Silurian, Devonian, Carboniferous and the Permian periods.
Climate
The climate of the Paleozoic Era changed during different periods. For example The Cambrian was warm worldwide, but following that into the Ordovician Period glaciers started forming, which led to an ice age. At the end of the era when Pangea formed the climate was likely dry, due to the inland parts of Pangea never touching the coast so rain clouds could never come to water the land.
The Continents
During the Cambrian Period the continents underwent a change the continents started shifting, by the Devonian Period they formed two supercontinents one named Gondwana and another Continent made up of the northern countries of the world. By the end of the era to be exact 250 million years ago the two supercontinents collided forming the huge supercontinent Pangea.
Major Changes to Landforms
One major change to landforms during the Paleozoic Era was in the Ordovician Period when glaciers formed and sent sea levels downward. Another major change to landforms during the Paleozoic Era was in a division of time called the Carboniferous Period when the Appalachian Mountains formed. At the end of the Paleozoic Era in the Permian Period the continents formed a supercontinent called Pangea.
Major Changes to Living Things
In the beginning of the time period many animals underwent a change this event was called the Cambrian Explosion. During the Cambrian Explosion arthropods evolved. Another major change to a living thing in the Paleozoic Era occurred 375 million years ago when lungfish evolved into frogs. Also during the Paleozoic Era, (540 million years ago to be exact) moss and mushrooms evolved from algae that lived on land.
End of Time Period
At the end of the time period 251 million years ago the Permian Mass Extinction wiped out 96 percent of marine animals and 70 percent of land animals.
