Modern Day Shanghi moved downwards in placement in 500 MYA
Crustaceous Period
Explosion starting the period in 540 MYA
Earth was one huge landmass from 540-485 but was not pangea.
The average oxygen levels during this period were 16.65
Biodiversity at the start= 1
Biodiversity at the end= 284
There was a huge global warming happening making earth more inhabitable
Crater was formed 500 MYA
Other than this there aren't many biotic events

Average levels were 20.6
175 MYA: Pangea starts to split making it so that the plates shift upward to the left
145 MYA: By the end of the period the plates have shifted upward left
200 MYA: Manicougan crater is formed
150 MYA: Morokweng crater is formed
Forests flourished and were lush

Biodiversity levels are 2746
Many plates shift today causing things such as mudslides and earthquakes. Since Pangea we have split off into continents.
Oxygen levels are 21.0
we have had numerous mudslides, tsunamis, earthquakes, hurricanes, tornados every year. They all leave an impact on the world in some way or another.
