At the time of the formation of this natural stone, the Mediterranean Sea dried up and the South Pole froze over. This caused the sea level to drop by 50 m.
Mineralogy
Due to the ice age, there were few plants that survived. The cool climate, on the other hand, gave rise to new species such as ash, beech and fir, which today make up our forests. At that time, the first real elephants settled. The first humans (Homo habilis) also appeared.
