Angela C Posted April 8, 2018 Share Posted April 8, 2018 I’m eager for some help identifying this shark tooth fragment I found while beach combing on Hilton Head, SC. I’ve found many, many sand tiger shark teeth here over the years, but this is by far the largest. It’s only a fragment, but the size with the huge nodule on the root is so very different from what I usually find on the beach. Is this indeed from a type of sand tiger shark? I’d love to learn more about it. Link to comment Share on other sites More sharing options...

Macrophyseter Posted April 8, 2018 Share Posted April 8, 2018 I agree with a pretty worn lower Hemipristis serra. Picture one shows some large, worn serrations at the lower part of the crown, which is a key trait in lower hemi teeth. And if that is not enough, the side of the tooth itself shows a large lingual proturbance, also a key trait in hemis. 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...
Angela C Posted April 8, 2018 Author Share Posted April 8, 2018 Thank you all so much! I’ve found small snaggletooth shark teeth on this beach before, but never considered that this could be a lower. Spot on! Link to comment Share on other sites More sharing options...
