masonboro37 Posted September 8, 2012 Share Posted September 8, 2012 (edited) Yes, it is me again. As I have said my tooth identification is getting better, but I still have a time with it. These two bitty shark teeth came from the Castle Hayne Formation, Eocene in North Carolina. These were picked up from a freshly washed area and were gleaming in the sunshine. They both look similar to two teeth I found a few weeks ago. I am possibly thniking that the tooth first tooth (left second pic) is Carcharhinus gibbesi . Maybe the second tooth in a Physogleus secondus. I have checked out elasmo and my field guide books. Any help is greatly appreciated.

Al Dente Posted September 8, 2012 Share Posted September 8, 2012 I would call the smaller one Galeocerdo latidens and the other is Physogaleus. Link to comment Share on other sites More sharing options...
S233 Posted September 8, 2012 Share Posted September 8, 2012 (edited) Hello masonboro37! I am really not that experienced with identifing, but i thought today would be a nice day to try....In my opinion, I believe the first is Galeocerdo latidens and the second is Galeocerdo contortus(I really dont know what the second one is i am just guessing for it) Oppps, Al Dente beat me to the first one.............

I would call the smaller one Galeocerdo latidens and the other is Physogaleus. Ok, great! In my NC Eocene field guide it states that the G. latidens is rare, 15-20 found a year. Do you agree?

The quarry is Eocene. Looked at the G. contortus is not listed in my books as Eocene. You are correct, not that. Thank you zachj! Process of identification "mistakes create wisdom".

S233 Posted September 8, 2012 Share Posted September 8, 2012 Okay well i at least got the first one correct.... : ) Link to comment Share on other sites More sharing options...
sixgill pete Posted September 8, 2012 Share Posted September 8, 2012 I believe Al Dente is correct, G. latidens and P. secondus. As far as the latidens, they definitely are not common, but I would not say rare, I have about 20 or so that I have found in the last 2 or 3 years. The other tooth is rather common, you should be able to find a much better example of it.
