skiman1016 Posted August 17, 2018 Share Posted August 17, 2018 I found these two teeth on Kure Beach in North Carolina when I was a kid. I have tried looking at guides online but I haven’t been able to find any that point out distinguishing characteristics of each species, they only show photos. Any help would be greatly appreciated.

Macrophyseter Posted August 17, 2018 Share Posted August 17, 2018 The bigger one is a requiem shark, genus Carcharhinus. Could be a bull shark (Carcharhinus leucas) The smaller one could be a grey reef shark tooth. If you're a fossil nut from Palos Verdes, San Pedro, Redondo Beach, or Torrance, feel free to shoot me a PM! Link to comment Share on other sites More sharing options...
skiman1016 Posted August 21, 2018 Author Share Posted August 21, 2018 I was wondering if the bigger tooth was some sort of requiem shark but wasn’t sure. Definitely had no idea on the smaller tooth, now that I looked up grey reef shark teeth I think that looks spot-on. Thanks so much for the help!

Paleoc Posted August 29, 2018 Share Posted August 29, 2018 Smaller one is a silky shark, note the notches on each side where the main cusp meets the shoulder serrations. 1 Link to comment Share on other sites More sharing options...
sixgill pete Posted September 1, 2018 Share Posted September 1, 2018 I agree with @Paleoc that the tooth on the left is silky shark. Carcharhinus falciformis. The other tooth, I do not believe it is a Bull Shark as suggested. The serrations start out course at the base then become fine towards the tip. I believe it may be a Galapagos shark, Carcharhinus galllpagensis. But I do want to add that the second tooth could be one of several Carcharhinus species as the teeth can be highly variable, even within the same jaw.
