jgheels2003 Posted July 13, 2017 Share Posted July 13, 2017 At the recommendation of a fellow member I'm reposting two of the teeth I found a few weeks ago at Oak Island, NC to help get some more feedback on what they might be. I've added a couple more shots, one of the underside as well. Both have serrated cutting edges, and I had previously thought that the bottom tooth was just a straighter more symmetric looking Bull/Dusky/silky tooth vs. a tiny looking meg tooth. Top one I have no idea, but was given some good possibility of an extinct white shark predecessor. Any input is greatly appreciated!!!! Original pic is at the bottom.

PaleoRon Posted July 13, 2017 Share Posted July 13, 2017 The top tooth looks like it could be hammerhead. The other is Carcharhinus. Along the lines of bull, dusky, brown, or similar. 1 Link to comment Share on other sites More sharing options...
Angie Posted July 13, 2017 Share Posted July 13, 2017 The bottom one looks like a Carcharhinus sp. to me (so indeed bull/dusky etc), but I can understand why you thought of a tiny meg, just think the bourlette would have been a little different and the shape would have been a little more triangular if it were a meg Not sure about the upper one! 1 Link to comment Share on other sites More sharing options...

In every other way it does look like one! I have no idea to be honest. Thank you for the response! Link to comment Share on other sites More sharing options...

The modern great hammerhead (Sphyrna mokarran) has serrated teeth and one or two others can have unserrated or serrated teeth. I think that tooth could be S. mokarran which is not often seen as a fossil (a few Pleistocene localities - maybe Pliocene as well). 3 Link to comment Share on other sites More sharing options...

Glad that You found out what (really) they are do to the more knowledgeable members here. Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."
