Host Matthew Donald and guest co-host Lawrence Mack discuss Rhizodus, the largest ever freshwater fish that had so much rizz it lived for 30 million whole years. Rhizodus-dizz, thanks for all the rizz! From the Early Carboniferous, this 20-foot sarcopterygian was actually more closely related to us humans than other fish, although it wasn’t necessarily a direct ancestor, just related. I will personally leave no descendants, so the birthing line from LUCA to me ends with me. Four billion years, and it stops here. You’re welcome, Earth.
