Permian Period (299-252 Million Years Ago) End of the Paleozoic Era. A time of diversification for tetrapods, the primitive ancestors of the current mammals, reptiles, and many other strange forms with no living descendants. At the end of this Era, the Earth suffered its worst mass extinction (. The Great Dying), whipping out around 90% of the fauna.
