Hybodus, the Crooked Tooth

(image source: https://walkingwith.fandom.com/wiki/Hybodus) Host Matthew Donald and guest co-host Natasha Krech discuss Hybodus, a seemingly ordinary looking shark that might have actually had a temporal range of nearly 200 million years because, evolutionarily speaking, it was perfect. Sharks, man. From the Late Permian to the Late Cretaceous, this 6-foot hybodont fish had little spikes adorning its dorsal fins as its distinguishing feature, which I guess made all the difference in the world. I mean, none of the other sharks had spikes and this one did, and correlation always equals causation!Want to further support the show?
