Join us on Cosmic Catastrophes as we explore the five major mass extinction events that reshaped life on Earth. From ancient ice ages and oxygen crises to volcanic eruptions, climate shifts, and asteroid impacts, discover the causes, survivors, and lasting impacts. Learn about resilient creatures like crocodiles and horseshoe crabs, the slim odds of enduring them all, and possible links to modern cryptids.
