We’re so glad you found this informative and enjoyable, thank you!

Hemipristis serra could definitely compete on this list; especially the individuals that possessed 2”+ teeth!

Wow. Seriously 2" Hemipristis serra teeth are from the king of the king of the carcharhiniforms. Here in FL I know those that big only come from South FL around Arcadia (the largest H. serra I've dug up is from a south tributary of the Peace river, 1.5 inch upper lateral, huge root very big serrations), in a slightly later time period than northish / mid peace river that's more mid or late miocene maybe. I've heard there were less megs in early Pliocene, probably why H. serra maxed out in size in early Pliocene or so on average, they naturally adapted to try to fill that niche... of course they're most likely my all time fav species, I can go on about their rise/ fall and evolution, I have a visual video about it.... and I made the first fossil shark podcasts (Elasmobranch evolution podcast, hard af to make/ edit quality solo podcasts and not burn out, that's largely why I only have a handful of episodes. I wouldn't call it dead tho, I made 1 episode so far this year.... tho lately I've fallen in love with North FL impressive springs and rivers, much more time sensitive to fight for defending those lately, sadly.... but I'll always have a soft spot for mega predatory sharks, and I'm beyond excited for hearing all this episode and beyond :]

Notidanodon could hang with some of the others on this list for sure!

Yes, especially for more modern Lamniformes, 10 feet an inch is a very rough generalization, and the 7-8 foot range per inch may be more accurate of an estimation.

Thank you for your kind words! We agree, Galeocerdo eaglesomi (especially the monstrous ones that used to inhabit what is now the Western Sahara region of Morocco) would have been fearsome predators. Paleocarcharodon from Morocco could reach very large sizes, and were likely apex predators in the Paleocene.
