bockryan Posted April 18 Share Posted April 18 Hi everyone - does anyone know offhand what non-Cretaceous formations are present at Holden Beach, NC? I have not been able to figure it out. For example, what formations might this tooth be from, and what is the age range? I assume Pliocene onwards? Link to comment Share on other sites More sharing options...
Fin Lover Posted April 19 Share Posted April 19 (edited) In SC, great whites are Miocene and younger...I assume it's the same in NC. This site mentions a few formations: https://ngmdb.usgs.gov/Geolex/UnitRefs/CastleHayneRefs_915.html Edit: they may not all be exposed there, but it at least gives you some names to research.

sixgill pete Posted April 20 Share Posted April 20 The great whites at Holden are likely from the Pleistocene Waccamaw Formation. To the best of my knowledge there is only Cretaceous PeeDee Formation and Pleistocene Waccamaw Formation. 1 Bulldozers and dirt Bulldozers and dirt behind the trailer, my desert Them red clay piles are heaven on earth I get my rocks off, bulldozers and dirt Patterson Hood; Drive-By Truckers May 2016 May 2012 Aug 2013, May 2016, Apr 2020 Oct 2022 Link to comment Share on other sites More sharing options...

I am not on board with great whites from the Miocene. C. hastalis, yes but not C. carcharias. Don't think they evolved until the mid Pliocene. But, I could be wrong!

Fin Lover Posted April 20 Share Posted April 20 (edited) @sixgill pete, maybe not...that's just what a local book I have says. I haven't done extensive research on it, just basic Google searches that indicate Miocene. Thanks for the information!
