Multiple rapid climate changes and lower oxygen levels in the water lead to the third major extinction. A strong increase in volcanism, probably caused by large continental shifts, is also contributing to this. Three quarters of all species living in the water are affected. Amphibians — vertebrates that can breathe air and live on land — have opened up the land as a new habitat. The first coelacanths also appear — they still exist today.
Shallow warm seas cover parts of the continents. The climate is initially warm, similar to the climate in Europe today. Later, the polar regions gradually cool down. Especially South America, which is close to the South Pole, is affected.
