It's 251.9 million years ago and the Permian is coming to an end. The Siberian Traps have been gushing ash and lava for more than 100,000 years turning once vibrant forestland into vast desolate wastes. The reign of the synapsids is neigh. Our old friend King Gorgonapsia has eaten his last dicynodont and is resigned to living the last few thousand years it will take to meld into the Triassic they way he wants to live them. The climate is getting ever more aired and hot too, so it's time to let the 'unders' be the 'outers' ya'll.
