第22期:二叠纪大灭绝

The gorgonopsid's sabre-teeth wound the scutosaur. The predator watches, as its prey grows weak from blood loss.

But before it can make its final move, something strange happens. The ground gets hot.

Enormous pressure builds beneath the surface, and lava spews into the air. But the lava isn't from one single volcano, the entire landscape is erupting.

It's a flood basalt eruption. A massive plume of mantle rises up from deep inside the Earth,

and pushes molten rock out through fissures in the Earth's crust. The lush paradise is now a lifeless hell.

The scutosaurs and the gorgonopsids are dead. They're the first casualties in the greatest mass extinction the world has ever seen, the Permian Extinction.
