Rhizodus, the Rooted Tooth

from Paleo Bites

(image source: https://dinopedia.fandom.com/wiki/Rhizodus) 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. Want to further support the show?
