britishcanuk Posted May 11, 2019 Share Posted May 11, 2019 Hi, i have this thresher tooth that was found in the same area as some typical A. grandis teeth from South Carolina. I’m leaning towards grandis for this one based on size, bit it has a symmetrical shape that none of my other grandis teeth have. I am not familiar with grandis anterior teeth, perhaps it that? Thoughts and opinions appreciated. cheers! Link to comment Share on other sites More sharing options...

Thoughts and opinions appreciated. cheers! My first thought was Alopias vulpinus or A. latidens (what is the age of the sediments ?), but the blade is well, blade-like, thinner in cross-section than I see with all of mine from LC, the Chesapeake Bay and SC, and from what I see on a few websites. Your observation about the symmetrical blade and the root don't speak to A. "grandis" to me either. I'm stumped.

ynot Posted May 12, 2019 Share Posted May 12, 2019 Possibly a posterior tooth. Maybe @MarcoSr or @Al Dente can offer an opinion. 1 Darwin said: " Man sprang from monkeys."
