-
Cambrian Period (570M-500M)
Life explodes and marine life is dominant specifically the trilobites.
Land is dry and rocky due to break up of a super continent and lack of vegetation. -
Ordovician Period (500M-435M)
Marine life flourishing and primitive plants start to form.
Climate is warm and wet with rising sea levels followed by an ice age. -
Silurian Period (435M-395M)
Animals and plants return after mass extinction that ended Ordovician period.
Temperatures climb and sea levels rise to create shallow marine environments and marine life flourishes again.
First true plants form. -
Devonian Period (395M-345M)
Huge variety of fish form, plants started to evolve to be able to survive on dry land.
Super continent was starting to form. -
Carboniferous Period (345M-280M)
Warm oceans and lots of coal is made suring this time due to huge forests.
Amphibians evolved into more complex organisms and the first reptiles started to form. -
Permian Period (280M-225M)
Pangea is formed after mass extinction during this period.
Climate extremes are occuring.
Reptiles became the dominant lifeform. -
Triassic Period (225M-195M)
Super continent is starting to break up.
Dinosaurs are the dominant lifeform and early mammals are starting to form. -
Jurassic Period (195M-136M)
Landmasses are crumbling and inland seas are starting to form. Humid subtropical climate.
Dinosaurs are dominant and are getting bigger and the first bird like animal is formed. -
Cretaceous Period (136M-65M
Continents are moving and changing the face of the earth.
Dinosaurs still ruled the landscape and kept evolving.
Flowering plants started to pop up everywhere. -
Tertiary Period (65M-1.8M)
Mammals were starting to become donimant and started to evolve.
Continents kept drifting to their positions today.
Climate spiked and then cooled.
Fish and whales were present . -
Quaternary Period (1.8M-Present)
Glaciers are on the move creating the landscape.
Continents are pretty much where they are today.
Humans evolve into us.
Whales and sharks rule the waters.
