PLB9eight Posted June 4, 2019 Share Posted June 4, 2019 Found this at GMR the weekend of the Aurora festival. Could this be an Angustidens or possibly older? It’s really worn so an exact ID might not be possible but it seems the cusps would have been really prominent had they not been so worn. This was sifted from the creek bed. Is Auriculatus a possibility in this case? It was very interesting to me. Link to comment Share on other sites More sharing options...
SailingAlongToo Posted June 4, 2019 Share Posted June 4, 2019 There was a cusp, but I'm afraid it's way too worn for a positive ID. Any attempt would be a guess. What does front look like? 1 Don't know much about history Don't know much biology Don't know much about science books.........

PLB9eight Posted June 4, 2019 Author Share Posted June 4, 2019 Thanks for the reply. I appreciate any feedback. I was afraid it might be too worn to tell much. I attached a shot of the front. Have you had any similar finds at GMR? I’ve read a lot about great whites, megs, and makos here but not other large species. This was our first visit and we only had a few hours before heading back to Virginia but it was a blast. Link to comment Share on other sites More sharing options...

When I was drilling wells throughout this area of NC, it was not uncommon to come across isolated patches of Paleocene, Eocene or Oligocene sediments, usually as lag deposits, so I'd say anything is possible. 2 'Those who cannot remember the past are condemned to repeat it.'

Rustdee Posted June 4, 2019 Share Posted June 4, 2019 I have heard of reworked Otodus obliquus found in GMR. Although yours is very worn, I do not see any evidence that the tooth ever had serrations. Like the others above, I am not certain here, though. It is an interesting find for the creek! Link to comment Share on other sites More sharing options...
sixgill pete Posted June 4, 2019 Share Posted June 4, 2019 I agree with a broken and worn out Otodus obliquus. GMR has Cretaceous, Pliocene and Pleistocene. No Eocene or Oligocene. I have quite a few of these worn out broken pieces from there and one decent tooth.

You have to be farther south in NC for Paleocene, Eocene or Oligocene deposits.

In each case not by much, only several miles, and that's broadly speaking; "conventional wisdom", if you will. The subcrop boundaries of these formations are for the most part very good approximates. It would not and is not unexpected to find erosional remnants or reworked material. I drilled a lot of holes between Washington and Jacksonville...

I drilled a lot of holes between Washington and Jacksonville... 25 miles to the closest Paleocene surface deposit and it is very small. 30 miles or so to the closest Eocene and Oligocene. I collect all of these areas regularly and live very close to GMR. There is no Paleocene, Eocene nor Oligocene exposed anywhere in the Greenville area.

Collecting scattered surface outcrops does not equate to full knowledge of the subsurface. Anyone claiming otherwise would be worth their weight in gold in the oil industry. They could save oil companies $millions in exploratory borings. Paleocene subcrops exist around Grifton, and Oligocene/Eocene (I can't remember which) in Chicod and close to Grifton, for example. Hardly 25 miles in either case. I never said these formations were exposed in Greenville, I said near. Then I mentioned lag deposits. Reworked and residual lag deposits are common in the NC coastal plain. That you believe the tooth to be a "reworked Otodus' ( a Paleocene-middle Eocene species) means that we are largely in agreement, excepting the fact that you believe that a geologist with decades of experience doesn't know the lithologies of these formations well enough to ID them when he sees them, that somehow you know better.
