Palaeo After Dark

In this episode we revisit the topic of taphonomy by discussing two papers that deal with actualistic taphonomy studies. Also, Amanda butchers potatoes, Curt becomes morbid, and James’s humor gets progressively bluer as the night goes on to the surprise of no one.

The gang returns to the subject of molecular clocks by discussing several papers that compare the results of molecular clock studies to the fossil evidence. Meanwhile, James tells stories of internet “fame”, Curt loses his composure, and Amanda will be right back.

The gang decides to revisit the past by returning to a few previous podcast topics and updating them with current research; starting with a survey of recent research into early vertebrate jaws. And like a snake eating its own tail, the conversation rambles about in circles and accomplishes very little. At the very least they manage to deliver an empathetic discussion of the impostor syndrome, seemingly for no reason. Meanwhile, Curt details teddy bear vivisection, James mixes pseudoephedrine and alcohol, and Amanda learns about the importance of eating before drinking.

After days of indecision about podcast topics, Curt snaps and decides to enact terrible revenge on the others. He holds the gang hostage and slowly tortures them by incessantly prattling on about species concepts and philosophy of science. Trapped in a room with only their snark (and some fresh cooked brisket) to defend themselves, Amanda and James struggle to survive the onslaught of boring. Can they hold out long enough, or will they succumb to the clawing insanity?

Apologies to Iceland, who we woefully misrepresent.

The gang gins up a flimsy excuse to talk about short-faced bears and megalodon. Also, Amanda researches topics for future podcasts on air, Curt becomes transfixed by Google image searches, and James's mind is broken by the thought of Mr. T.
