Elena919 Posted January 31, 2017 Share Posted January 31, 2017 I found an unusually shaped tooth in the Belgrade quarry a couple of weeks ago. I am a baby fossil hunter, but it appears to be some type of very small shark or ray tooth. I am having trouble getting clear pix, but these are my best ones. The middle pic is the bottom of the tooth. Any help would be appreciated. Link to comment Share on other sites More sharing options...

The place she is talking about is the Belgrade Quarry in Mayesville, North Carolina. There is a community just outside of Mayesville called Belgrade, just over the county line.

Jniederkorn Posted February 2, 2017 Share Posted February 2, 2017 Awesome tooth and great pictures! The North Carolina Fossil Club has photos and information on these teeth in their Volume III book, on page 36. 1 Link to comment Share on other sites More sharing options...
Paleoc Posted February 15, 2017 Share Posted February 15, 2017 Ginglymostoma, Nebrius seems to have vanished from North America by then. The center cusp in Ginglymostoma is much larger in comparison with the side cusps unlike Nebrius. Link to comment Share on other sites More sharing options...

Every reference I have seen on the Belgrade and River Bend Formations, the 2 Oligocene Formations present at the Belgrade quarry; identifies the Orectolobiformes from there as Nebrius. Do you have a reference showing something different, I would be interested in that. That would mean I have several teeth mislabeled.

Do you have a reference showing something different, I would be interested in that. That would mean I have several teeth mislabeled. I agree with Paleoc. While the number of cusplets/serrations is high for Ginglymostoma, the main cusp is clearly larger (higher and broader) than the other cusplets. Also, in Nebrius the apron extends well below the level of the base of the root. In Ginglymostoma the apron either doesn't reach that low or extends just below that level. There isn't a photo of that side but it appears the apron doesn't extend below the root since the base of the root seems level with the surface it's on. Actually, I should look at my teeth too - probably some mislabeled stuff in there. Jess 1 Link to comment Share on other sites More sharing options...
Paleoc Posted March 22, 2017 Share Posted March 22, 2017 New post with missing pictures, I had moved the images to another folder. In Nebrius, while the center cusp;is obviously larger than the lateral cusps it is not as radically larger as in Ginglymostoma. Also note how far down the apron extends and how broad it is. On the My Fossil site, there is a near flawless one from Belgrade. However, the apron is not nearly as broad as the apron as on Nebrius. This Nebrius image sort of exaggerates the size of the center cusp in relationship to the side cusps. Looking at it in person, the center cusp on Nebrius is about twice the height of the immediate lateral cusplets. In Ginglymostoma, it is about 3 - 3.5 times the size. Also the bottom of the apron is not as wide and doesn't extend down as far. Nebrius Ginglymostoma Link to comment Share on other sites More sharing options...
sixgill pete Posted March 23, 2017 Share Posted March 23, 2017 @Paleoc @siteseer Here are a couple of pics of an Orectiloboforme tooth I have from Belgrade Quarry. It was found in the basal sand at the bottom of the quarry where the Psammechinus and Echinocyamus echinoids are found. It is lower Paleogene; Oligocene River Bend Formation. Probably Rupelian in age. To me this tooth matches Nebrius obliquus known from the Eocene Castle Hayne. I think my tooth matches the tooth in question pretty well. What are your thoughts on this and on my ID?

Paleoc Posted March 23, 2017 Share Posted March 23, 2017 That looks like Nebrius. Of course the River Bend is older than the Belgrade formation from which the Ginglymostoma is coming from. Perhaps Nebrius was replaced at this time. Nice tooth. Link to comment Share on other sites More sharing options...
