Summary

This episode, we’re talking mass extinction again! Last time, we touched on the event that ended the Age of Dinosaurs, but this time – by listener request! – we’re discussing the event that started it: patterns and potential causes of the end-Triassic mass extinction. In the news: a colorful armored giant; a surprise apex predator; epigenetics and variation; and some fast-evolving big-headed geckos!
