sixgill pete Posted March 14, 2017 Share Posted March 14, 2017 Hi everyone, I found this tooth in some micro matrix I received from a friend. It is from a Cretaceous site in southeastern N.C., Cretaceous Black Creek Group; Campanian Not sure if it is Tarheel, Bladen or Donoho Creek Formation. The site is known for marine and land finds. I just dont see shark in this tooth. I cannot really say why, but could be wrong. So here it is, help. It measures in at a whopping 4 1/2 mm wide and about 4 mm long.

britishcanuk Posted March 14, 2017 Share Posted March 14, 2017 Kind of reminds me of a worn cookiecutter shark tooth. The teeth on right of this photo look similar. Link to comment Share on other sites More sharing options...

Al Dente Posted March 14, 2017 Share Posted March 14, 2017 I think it is a posterior shark tooth, don't know which species. There is a lot of erosion of the root. Link to comment Share on other sites More sharing options...
Plax Posted March 14, 2017 Share Posted March 14, 2017 If it's from me keep in mind that there's Tarheel, Bladen and some Raysor in that lag. Looks cretaceous to me though. the weird bend is throwing me off. Link to comment Share on other sites More sharing options...
Al Dente Posted March 14, 2017 Share Posted March 14, 2017 Here are some mako posterior teeth from Marco Sr.'s collection found here http://www.thefossilforum.com/index.php?/topic/59995-extant-isurus-oxyrinchus-mako-shortfin-shark-jaw/ A lot of lamnid posterior teeth look alike. Could be Carcharias or Scapanorhynchus. Link to comment Share on other sites More sharing options...
