Josh_irving Posted December 18, 2023 Share Posted December 18, 2023 Hi everyone, Are these two teeth C. Hubbelli or C. carcharias? thanks, in advance. 1. 2. 1 Link to comment Share on other sites More sharing options...
ted coulianos Posted December 18, 2023 Share Posted December 18, 2023 (edited) From the size of the serrations I would be inclined to i.d. these as both Carcharodon carcharias; C. hubbeli (from what I understand) has much finer serrations than what your images show. C. hubelli has been deemed a transitional, fine toothed form from Carcharodon hastalis; both are found in the upper Miocene & Pliocene deposits in the Attacama desert region of Chile. Perhaps one of the shark experts can weigh in. Very nice specimens regardless! Edited December 18, 2023 by ted coulianos 2 1 Link to comment Share on other sites More sharing options...

hemipristis Posted December 19, 2023 Share Posted December 19, 2023 I too would go with C. carcharias. I have a few from the Netherlands, and they match @ted coulianos description.
