attached are pictures of a tooth I found in the spoils pile from Lee Creek Mine at Urora Fossil Museum in North Carolina. While the tooth does not have any evidence of missing cusplets, it could have had them at one time. There are very small serrations on both sides of the crown. The front top of the root is almost flat towards the back of the tooth. The root also has a deep groove on the back side of it. Thank you for any assistance you can provide.
Victor…thank you for your response. I do have to disagree with your suggestion that it is from the Carcharhinus genus. None of those teeth have exaggerated flat roots. I was leaning more towards Carcharia cupidity but not 100% convinced. Thanks again.
I was thinking maybe one of the upper lateral positions of Carcharhinus isodon (perhaps like the tooth labelled as 10 or 11 here). It’s difficult to tell from the images if it is indeed serrated or if the cutting edge is chipped. If it is serrated, it’s not a sand tiger shark.
Victor…I am still not sure if it is. I will be going up to Aurora next month and maybe I can get a definite ID on it. Thank you so much for taking the time on ID ing this tooth. I will let you know if I get a decision on it. Good luck fossil hunting this year.
