Podcast 87 - Leaving a Mark; Trace Fossil Changes Through Time
Everybody is back in the same zip code for an extra special episode focusing on fish faces and evolving trace fossils through time. Also, James enjoys the perks of podcasting in person, Amanda decides to be as general as possible, and Curt decides to aggressively Godwin's Law the podcast. Also, the gang invents a mixed drink on air and then things get.... weird. This episode is pretty much all over the place.
