Going caving this weekend reminded me that I never shared BTS photos from Episode 5 of @eonsshow Life and Death on Pangea! 🎬 In this episode, we were trying to convey the devastation of life on planet earth in the wake of The Great Dying… It may not be the most famous mass extinction (that asteroid gets a lot of press ☄️ ) but it’s undoubtedly the biggest mass extinction, and it was in part triggered by MASSIVE amounts of basaltic lava oozing out from cracks in the ground of what is today Siberia (covering up to 3 million miles 🌋). However, it’s really the volatiles released with the lava (carbon dioxide! methane!) that led to extinction beyond the landscape of lava (which, when cooled, might have looked like the landscape here at @cratersofthemoon_nps). Excess CO2 in the atmosphere caused worldwide surface temperatures to rise to over 100F and excess CO2 in the oceans led to acidification on top of the oxygen depletion caused by warming ocean temperatures. In the end, over 70% of land species were wiped out, and up to 90% of ocean species. How, after all this, did life - uh - find a way? Well, you’ll have to tune in to find out. All six episodes of Life and Death on Pangea are streaming now on the @pbs website and the @pbs app!
