Hadean Era  (4600 to 3800 mya)  –  800 million yrs Archaean Era (3800 to 2500 mya) - 1.3 billion yrs Proterozoic Era (2500 to 543 mya)  - 1.96 billion yrs Precambrian  (4,500 to 543 mya)  - 3.96 billion yrs
You can think of the Precambrian time as the earliest time of earth formation and the first forms of life on it.  You can liken it to a pregnancy in which basic elements and life forces form the infant. Once the infant is born, we speak of a human life time. Earth’s Life Time is called the PHANEROZOIC EON. Earth’s life time can be divided into  old age,  medieval (middle) age,  and young age Paleozoic  Mesozoic  Cenozoic
Permian  (290 to 248 mya) Pennsylvanian (323 to 290 mya)  Mississippian  (354 to 323 mya)    ( Carboniferous) Devonian  (417 to 354 mya) Silurian  (443 to 417 mya) Ordovician  (490 to 443 mya) Cambrian  (543 to 490 mya)         Paleozoic Era  -old age- (543 to 248 mya) -295 million yrs Cretaceous (144 to 65 mya) Jurassic  (206 to 144 mya) Triassic  (248 to 206 mya) Mesozoic Era -middle age-  (248 to 65 mya) - 183 million yrs Period: Quaternary (1.8 mya to today) Tertiary  (65 to 1.8 mya)       Cenozoic Era -young age- (65 mya to today) - 65 million yrs Phanerozoic Eon   (543 mya to present)
Carboniferous ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],7 Periods : Permian (290 to 248 mya) Pennsylvanian (323 to 290 mya)  Mississippian (354 to 323 mya)  Devonian(417 to 354 mya) Silurian(443 to 417 mya) Ordovician (490 to 443 mya) Cambrian (543 to 490 mya)     Paleozoic Era  -age of  old life- (543 to 248 mya)

2 Periods : Quaternary  (1.8 mya to today) Holocene  (10,000 years to today) relative warm period; homo sapiens sapiens Pleistocene  (1.8 mya to 10,000 yrs) humans spread in the world most continents covered with glaciers= ice age mammoths prevalent and then extinct Tertiary   (65 to 1.8 mya) Pliocene  (5.3 to 1.8 mya)   Antarctic polar cap formed Miocene  (23.8 to 5.3 mya)   many grasses; kelp forests Oligocene ( 33.7 to 23.8 mya)   first elephants with trunks, early horses   Eocene  (54.8 to 33.7 mya) small hoofed animals (ungulates) Paleocene  (65 to 54.8 mya)  starting point for the great evolution of mammals Cenozoic Era -age of young life- (65 mya to today)

Notes de l'éditeur

  1. Modern Stromatolites found at Hamelin Pool, Western Australia. Cyanobacteria have heterocyst for nitrogen fixation and cells for photosynthesis. The photosynthesis produces the byproduct oxygen which was instrumental in building an oxygen rich environment in the Precambrian time.
  2. Illinois flat lands home to carboniferous rainforest 300 million years ago. Ferns made up a large portion of vegetation during this period. Also thought of at the Golden Age of sharks…with evolution of fish into much of the shapes and types we see today. Most dominant insect was the cockroach, fossil finds size it up to 3.5 inches in the carboniferous era. First vertebrates (lampreys)
