Marine organisms were the dominant form of life and this resulted to about 85% of them to die off.]]> 2021-03-05 18:23:05 UTC https://padlet.com/ehov5286/1rs2mhur6ujd6b45/wish/1274959388 ehov5286 https://padlet.com/ehov5286/1rs2mhur6ujd6b45/wish/1275000154 Two sharp pulses of death occurred and global cooling most likely is the cause of this extinction. The massive drop of temperatures affected marine life and plants. ]]> 2021-03-05 18:31:46 UTC https://padlet.com/ehov5286/1rs2mhur6ujd6b45/wish/1275000154 ehov5286 https://padlet.com/ehov5286/1rs2mhur6ujd6b45/wish/1275048054 The main theory of this extinction is massive volcanism.
