I personally would just identify this as Carcharhinus, but @bill-heim may be daring enough to try to identify it to species.

I was making a bold guess based on the size and robustness, was wondering if anyone would call my bluff.

An unusually large C. perezii (did they name it after you Victor? – joke) Apparently the teeth become wider after they reach a certain size which is common to many sharks. Due to abrasion, it is hard to see the key features. C. perezii has a small notch were the coarser lower serrations meet the finer upper serrations. Due to wear it’s hard to see but it is there. The serrations on the lower part of the tooth are considerably coarser while in C. leucas they are pretty close to the same all along the tooth, finer towards the tip but not as radically so. C. leucas tends to have a large dental band (bourlette) as well which this lacks. This is an upper A3 tooth.

Thanks so much @bill-heim!!! That’s the first time someone’s explained a Carcharhinus species to me in a way I can understand
