The end Permian extinction drastically cut the diversity of life on Earth. Some groups went extinct, while a few species in other groups made it through. Sea urchins, once diverse during the Permian, were devastated—only one species survived. Ammonites, too, were hard hit. The Permian is the final period of the Paleozoic Era. It began about 299 million years ago and lasted until 252 million years ago. The greatest mass extinction that has ever occurred on earth took place at the end of this 47-million-year period.Kansas was once the bed of a vast shallow body of water called the Permian Sea.
