Episode 65 - The Late Devonian Extinction(s)

July 13, 2019

It’s Episode 65, and you know what that means … extinction! This time, we address the ancient and confusing Late Devonian extinction. This is traditionally considered one of the “Big 5,” but it doesn’t seem to be “one” extinction at all. Geologists and paleontologists continue to work at piecing together the various causes and consequences that create an extended series – several millions years long – of very unfortunate events that altogether comprise one of the worst biological crises in Earth history.

In the news: tyrannosaur smells, peccary behavior, and a talk (by us) about our podcast!
