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.
