Period: 543 BCE to 252 BCE
PALEOZOIC ERA
It is the era where plants begin their invasion to the earth's surface. We were able to see the development of therapods, which were vertebrates with fingered limbs, which were limited to humid environments. -
541 BCE
Cambrian
At that time, life on Earth did not exist, however, things were different in the oceans, because there were many types of beings. This is due to an event known to many as the "explosion of life", in which complex multicellular organisms began to emerge. -
Period: 541 BCE to 490 BCE
Cambrian
-
490 BCE
Ordovician
During the Ordovician period, wildlife was already abundant in the oceans. There is a great biodiversity from the smallest and most primitive animals to the most complex and evolved. We started producing arthropods. It is a fairly abundant feature in this period. -
Period: 490 BCE to 443 BCE
Ordovician
-
443 BCE
Silurian
This is the geological time that precedes the Devonian period. It is distinguished by the fact that the oceanic extent is high, which means that there is an extensive record of marine sediments on all continents. Shallow continental seas extend into the tropics. -
Period: 443 BCE to 417 BCE
Silurian
-
417 BCE
Devonian
Amphibians appeared. There are still large corals, ammonite mollusks, and arthropods. On land, forests continue to grow and form, as do arthropod species and families. -
Period: 417 BCE to 354 BCE
Devonian
-
354 BCE
Carboniferous
New seas were created within the continents and global temperatures changed. The continents are grouped together in the supercontinent Pangea, squeezing each other and resulting in a very active mountain formation. -
Period: 354 BCE to 289 BCE
Carboniferous
-
290 BCE
Permian
During the Permian period, there were significant climatic changes with the general tendency of tropical climates to become increasingly dry. There is shrinkage in the swamps. A large number of tree ferns (Lycopodiophyta) and amphibians that need humid conditions have disappeared. -
Period: 290 BCE to 252 BCE
Permian

Period: 251 BCE to 56 BCE
MEZOSOIC ERA
The Mesozoic period is divided into three periods: Triassic, Jurassic, and Cretaceous. New flowering plants and insects multiply. More modern telescopic fish start to appear -
250 BCE
Triassic
The Triassic climate is generally hot and dry, which leads to the formation of deserts and volatiles. The large size of Pangea limits the regulatory influence of the ocean; Its continental climate is very seasonal, with very hot summers and very cold winters. Possible strong monsoons in Ecuador -
Period: 250 BCE to 206 BCE
Triassic
-
206 BCE
Jurassic
This period is characterized by the predominance of large dinosaurs and the division of Pangea on the continents of Laurasia and Gondwana. Since then Australia has split (during the Upper Jurassic and early Cretaceous), in the same way that Laurasia split into North America and Eurasia. -
Period: 206 BCE to 144 BCE
Jurassic
-
144 BCE
Cretaceous
There was a period of obvious dinosaur dominance, making this the most famous period of the Mesozoic era. ... The beginning of the rift of the supercontinent Pangea was remarkable, which allowed the formation of the present continents. -
Period: 144 BCE to 65 BCE
Cretaceous
-
66 BCE
Tertiary
The archaic tertiary period includes the Paleogene and the Negene. The end of the last ice age and the rise of human civilization. -
Period: 66 BCE to 50
CENOZOIC ERA
The Cenozoic era began with the extinction of the dinosaurs about 66 million years ago. ... also known as the "Age of Mammals" because it was the preferred lifestyle 66 million years ago. -
Period: 65 BCE to 2 BCE
Tertiary
-
2 BCE
Quaternary
The Quaternary period is characterized by a decrease in ambient temperature, which sometimes leads to so-called ice. During this time, temperatures dropped dramatically, glaciers formed, and even a large part of the continent was covered with thick layers of ice. -
Period: 2 BCE to 50
Quaternary
