Questions about any large and currently unnamed Ctenacanthiformes sharks known
Joseph Fossil posted a topic in Questions & Answers
As I have been researching large ctenacanthiform sharks from North America, I've been wondering if there are any known globally that are currently unnamed. I definitely know of the large Ctenacanthiformes Saivodus stratus (found in both what is now North America and Great Britain), the large Ctenacanthiform from the Permian Kaibab formation in Arizona, and the 'Texas supershark' (a likely large species of Gilkmanius) from the Pennsylvanian Texas Graham formation (all three as larger or larger than an adult Great White Shark (Carcharodon carcharias)). But are there any large ctenacanthiformes (at least in size comparable to a modern day adult Great white shark (Carcharodon carcharias)) currently unnamed that are also known? Ctenacanthiformes are known from North America, Greenland, Europe, Asia, and South America. https://www.mindat.org/taxon-P34476.html Even though study of Ctenacanthiformes as a whole is just starting to become more through within the past few decades, I'm wondering if anyone on the forum is aware of any currently unnamed Ctenacanthiform fossils from areas outside of North America of Great White Shark (Carcharodon carcharias)) size?- 3 replies

Location: Missouri Period: Pennsylvanian Formation: Iola Formation (Raytown Limestone Member?) Hello once again. I happened to have come across a Cladodont tooth of some kind but I am unsure of what it exactly belongs too. I am stuck between Glikmanius or Saviodus. I'm thinking its the later due to how straight the tooth seems, but I am not sure how to truly tell the two apart. I notice this specimen is oddly white compared to the black teeth I'm used to.
