Animal Armageddon – The Great Dying (Discovery Channel HD Documentary)
250 million years ago, the Siberian Traps erupt into an active volcano. The eruption of the Traps causes land ecosystems to be put under serious stress, due to severe climate change caused by basalt flow volcanic eruptions in Siberia. This modifies the chemical composition of the atmosphere. The result is the largest mass extinction in Earth’s history. Most Gorgonopsids, Dicynodonts, and numerous other creatures became extinct. However, both Proterosuchus, and Thrinaxodon, (the ancestors of archosaurs and mammals, respectively), both manage to survive the mass extinction, and go on to become extremely successful, inheriting the Earth, as well as fighting, with each other, for supremacy, during the succeeding Triassic Period.
