What was the atmosphere like in the Permian period?
oxygen made up 23% of the mean (average) atmospheric volume, which is 115% of the amount of oxygen today. Carbon dioxide made up an average of 900 parts per million, which is three times the pre-industrial level of CO2 today. The average temperature was 2 degrees Celsius, or 3.6 degrees Fahrenheit, warmer than today.
Why are corals a dominant lifeforms on Earth during the Silurian period?
Corals were a dominate life form during the Silurian period because the climate was much warmer in the oceans and the ocean's were actually larger than they are today. This gave coral a chance to grow large and strong.
