Ancient Oceans Turned Deadly—Here’s How

Imagine nearly half of all ocean life just...vanishing. Turns out, 530 million years ago, toxic hydrogen sulfide gas wiped out about 45% of marine species!

It’s a wild reminder that sometimes, the real killer is what you can’t see (or smell). #Science #AncientExtinction #OceanMystery
