ted coulianos Posted January 17 Share Posted January 17 First impression, looks like a worn Tiger Shark, Galeocerdo aduncus, lateral tooth.

hemipristis Posted January 17 Share Posted January 17 I would posit a great hammerhead, Sphyrna mokarran. A few modern examples for comparison: 'Those who cannot remember the past are condemned to repeat it.' George Santayana Link to comment Share on other sites More sharing options...
ThePhysicist Posted January 17 Share Posted January 17 I think it's simply Carcharhinus. It lacks the deep nutrient groove seen in the great hammerhead, and the strong notch and large serrations on the distal shoulder of tigers. 1 "Argumentation cannot suffice for the discovery of new work, since the subtlety of Nature is greater many times than the subtlety of argument." - Carl Sagan "I was born not knowing and have had only a little time to change that here and there." - Richard Feynman Collections: Hell Creek Microsite | Hell Creek/Lance | Dinosaurs | Sharks | Squamates | Post Oak Creek | North Sulphur River | Lee Creek | Aguja | Permian | Devonian | Triassic | Harding Sandstone Instagram: @thephysicist_tff Link to comment Share on other sites More sharing options...
Fin Lover Posted January 17 Share Posted January 17 My initial thought was Carcharhinus but then I was teetering between that and tiger. The root definitely looks like Carcharhinus. Maybe the wear on the crown just exaggerates the notch and degree of slant? Fin Lover My favorite things about fossil hunting: getting out of my own head, getting into nature and, if I’m lucky, finding some cool souvenirs.

MarcoSr Posted January 17 Share Posted January 17 22 hours ago, Fossildude19 said: @Al Dente @MarcoSr @sixgill pete Normally, when I see a picture of a tooth, I get a general feeling of what it is. Maybe because of the serration damage and crown tip rounding, I didn't get an impression for this one right away. I'll show with a couple of pictures of extant shark teeth that the tooth is not a tiger shark (Galeocerdo) tooth or great hammerhead shark (Sphyrna mokarran) tooth. Look at the areas that the arrows point to on the posted tooth. Among other differences, the tiger shark (Galeocerdo cuvier) tooth crown bulges out and the posted tooth crown necks in. As already said, the great hammerhead shark (Sphyrna mokarran) tooth root has a "deep nutrient groove" and the root of the posted tooth doesn't have a visible nutrient groove. Although there are other possibilities, a Carcharhinus tooth is a definite possibility. Marco Sr. 2 "Any day that you can fossil hunt is a great day."

Sonickmonx Posted January 21 Share Posted January 21 I certainly agree this tooth is atypical for a Charleston area tooth, but it definitely strikes me as carcharhinus, Marco did a great explanation. You can also make out where the bourlette would have been, as the bull shark has a bourlette that’s often not preserved but is very useful in identification!
