The biosphere was subjected to a number of hyperthermal warming-driven mass extinctions during the late Palaeozoic-early Mesozoic that nearly extinguished life from the planet. Why was life pushed to the brink so often during this period of Earth history and what were the lasting effects, both evolutionary and ecologically, from these crises? I present a number of case studies from the Late Permian, Late Triassic and Early Jurassic extinction events in an attempt to answer these questions.
