Thanks T.D.  I am guessing isurus for the first and abdounia recticona for the second one,  but just not sure.

Wild guess...

1.     Physogaleus "secundus" (WINKLER, 1874) - Extinct requiem shark genus. Symphyseal tooth.

2.     Abdounia recticona (WINKLER 1873) - Extinct requiem genus.

I think Tony has nailed it.

The cusps on that second tooth are unlike anything I’ve seen, very nice.:)

A. recticona are very common in some of the Eocene exposures in North Carolina.

I’ve never had the fortune of hunting in those places, I’ll have to look into that next time I’m in the Carolinas. :D

I will agree with Physogaleus for the first and Abdounia for the second, even though there is something odd about the shape of the second one. Our mutual friend (EM) would probably label the first one as a Galeocerdo alabamensis symphyseal and the second as Abdounia claibornensis, Abdounia recticona usually has fewer cusps than A. claibornensis.
