The Archean is one of the four geologic eons of Earth's history. Occurring 4,000 to 2,000 million years ago. It is the 2nd geological eon.
-
Singular cellular organisms are being created and are producing oxygen which fills the atmosphere with breathable air which makes it livable for other organisms.
-
The Proterozoic is a geological eon spanning the time from the appearance of oxygen in Earth's atmosphere to just before complex life on Earth. 2,500 million years old. The 3rd geological eon.
-
The First multicellular organisms were created 380 years after the single cellular organisms created oxygen.
-
The Phanerozoic is the current geological eon that we are living in right now and the one where an abundance of life started showing up. It covers 541 million to present. It is also the 4th and last geological eon.
-
The Paleozoic Era is the earliest of three geologic eras of the Phanerozoic Eon. It lasted from 541 to 251.902 million years.
-
The Cambrian period is the first geological period in the Paleozoic Era. The Cambrian spans 55.6 million years.
-
First animals and they were all sea animals.
-
The Ordovician period is the second geological period in the Paleozoic Era. The Ordovician period spans 41.6 million years from the end of the Cambrian period.
-
Crinoids are ancient animals that appeared in the seas 300 million years before dinosaurs.
-
The Silurian period is the third geological period in the Paleozoic Era. The Silurian period 24.6 million years from the end of the Ordovician period.
-
The Devonian period is the fourth geological period in the Paleozoic Era. The Devonian period spans 60 million years from the end of the Silurian period.
-
Underwater plants such as horsetails, Ferns, and Club mosses began to evolve and turned into a forest. Which at the time was known as the Earth's first forest.
-
The Carboniferous period is the fifth geological period in the Paleozoic Era. The Carboniferous period spans 60 million years from the end of the Devonian period.
-
Due to the continental shift that created Pangea the first mountains were created. Mountains are created when two continents hit each other and a gigantic piece of the Earth goes up creating a mountain.
-
The Permian period is the sixth and final geological period in the Paleozoic Era. The Permian spans 47 million years from the end of the Carboniferous.
-
The Largest mass extinction happened. It happened due to the new supercontinent formation called Pangea which introduced new extremes to weather such as volcanoes and tundras.
-
The Mesozoic Era is the 2nd of the three geological eras in the Phanerozoic Eon. It lasted from 252 to 66 million years.
-
The Triassic period is the 1st geological period in the Mesozoic Era. The Triassic spans 50.6 million years.
-
The First dinosaurs are created. Also, Pangea starts to break apart.
-
The Jurassic period is the 2nd geological period in the Mesozoic Era. The Jurassic spans 56 million years.
-

-
The Cretaceous period is the 3rd and final geological period in the Mesozoic Era. The Cretaceous period spans 74 million years.
-
The Cenozoic Era is the 3rd and final Era in the phanerozoic Eon. It extends 66 million years from the Mesozoic Era.
-
This is the 2nd largest extinction wiping out all of the dinosaurs and opening a path for mammals to take over and grow
-
The Tertiary period is the 1st geological period in the Cenozoic Era. The Tertiary period spans 55 million years.
-
The earliest ancestor of humans called "Lucy" was found during this time. A great breakthrough.
-
The Quaternary period is the 2nd and last geological period in the Cenozoic Era. The Quaternary spans around 10 years to now.
-
Homosapiens begin as cavemen and start to dominate the planet and the mammals that ruled before.
