Episode 494 - Mass extinctions and recovery in our oceans

August 1, 2022

What happens when most life in the ocean just dies off? Our oceans have seen many mass extinctions in the past, how long does it take to recover? What happened at the end of the Permian that caused massive extinctions in the ocean? What creatures were best able to survive when 80% of the rest of life in the ocean died?
