Cretaceous Mass Extinction
One of Earths five major extinctions. It was the last know major extinction that occured. The most prevelant theory of how this happend is from a giant comet -
***THIS IS NOT PART OF TIMELINE***
Due to the way that i had to order the dates, this timeline appears backwords because this timeline creater does not support the very far past time. so for example the year 4600=4.6 billion years ago, or the year 300= 300 million years ago. -
Oxygen enters Atmosphere
the isotopic ratio of sulfur transformed, making oxygen a major part of the earths atmosphere -
First Multicelluar life
one billion years after earthg was formed, the first multicelluar life appeared. The first multicelluar animal did not appear untill 600 million years ago -
First forms of life on Earth
The first life started near deep sea hydrothermal vents, and the life form was not multicelluar, but it was like a bacteria. The first know organisim is the Microbial Mat. -
