The gang discusses how exceptional fossil preservation can change our understanding of ancient life, focusing specifically on two new studies that offer insight into trilobite reproduction and hyolith evolution respectively. And when faced with the challenge of describing the indescribable weirdness of hyoliths, the gang falls back on their old mainstay of saying "It's weird" and derailing the conversation every five minutes. But hey, there's a 20 minute conversation about science outreach in the middle there that comes out of nowhere that's not terrible.... so that's something...

We're very... very... sorry.
