Show Notes
In this episode, the gang discusses two papers that use morphological and chemical proxies to understand the metabolism of fossil animals. Did all early tetrapods breathe through their skin? Were mosasaurs warm blooded? Also, James accidentally goes full stealth, Amanda instigates a Civil War, and Curt gets not-it'ed into bumbling through explaining geochemistry.
