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

Hi! Me and @Tales From the Shale are actively thinking of going on a fossil hunting trip in Alton Illinois (right by St. Louis, Missouri) this week to analyze the Mississippian period St. Louis limestone and I'm wondering if anyone else has gone down there? https://www.mindat.org/feature-4232679.html We're specifically looking for fossils of the Meramac group and though we have a quarry or two, we're thinking of also checking out any road cuts in the area. I'm wondering before we go on the fossil hunt (likely this Saturday), could anyone offer some info on any good road cuts in the Alton area as well as quarries and if there are also a descent amount of fossils in the Spergen limestone too?
