Wolfehunt Posted September 1, 2022 Share Posted September 1, 2022 (edited) I have just gotten a great white tooth. It measures right at 61mm or 2.4 inches. I’m curious how large the shark ? Any idea of a calculation? I tried one but I couldn’t make since of it. Help would be awesome. Edited September 1, 2022 by Wolfehunt Link to comment Share on other sites More sharing options...

It's too bad that information wasn't included with your purchase. There really isn't a formula. There has always been the "rule" of one inch per 10 feet in length but that doesn't work for larger individuals because as the shark reaches maturity, it grows at a slower rate and it fills out more in the body. The largest teeth are the upper anteriors and you have one of those. Modern great white teeth over 2 inches are rare and a 2 1/4 tooth would be a whole other level of rarity. I think it would be safe to say that since your tooth is a level of rarity even beyond that, it's probably from a shark among the largest ones caught so I'm thinking an 18-footer +/- maybe a foot and a half to give a range. I would declare it could be from an individual over 20 feet but you'd think someone would have made the news with that one. Like I said, it's hard to say but that's an unusually large modern great white tooth. I've seen a few larger fossil ones. I used to have a 2 3/4-inch one from Peru.

I was gonna say... maybe ask the shark? I'm betting it's still around! Fossils? I dig it. Link to comment Share on other sites More sharing options...
Wolfehunt Posted September 1, 2022 Author Share Posted September 1, 2022 The individual I purchased this from said 19 feet but I wanted to see if I could back that up some how. Link to comment Share on other sites More sharing options...

Al Dente Posted September 1, 2022 Share Posted September 1, 2022 (edited) Here’s a graph using tooth width, or a sum of tooth widths which might not be helpful, from this paper-https://palaeo-electronica.org/content/2021/673-1140/3312-estimating-lamniform-body-size-figures#f6 Edited September 1, 2022 by Al Dente 1 Link to comment Share on other sites More sharing options...
Wolfehunt Posted September 2, 2022 Author Share Posted September 2, 2022 I’ll see if I can figure it out? Lol. If not I’ll just post pictures of the measurements and let some genius figure it out for me Link to comment Share on other sites More sharing options...
Wolfehunt Posted September 2, 2022 Author Share Posted September 2, 2022 Yeah that’s all way to complicated for me. I can’t ever start to figure out what to measure ..:( Link to comment Share on other sites More sharing options...
Wolfehunt Posted September 2, 2022 Author Share Posted September 2, 2022 (edited) Using this I calculate 20 feet. But I’d feel safer saying it was 18-19 footer. I know my tooth is not the biggest tooth out there. I know of at least 7 teeth that are bigger then mine and maybe 10 others about that same size.

It sounds like you have an idea of what's been out on the market and/or you know some of the other collectors into big great whites. I think you have a good ballpark especially since what your source said fits in that rather tight range. Among anyone of our species, a tall individual might have smaller teeth than a shorter one. Knowing that there aren't that many specimens around the size of your tooth and just some larger is good info to have as well. 1 Link to comment Share on other sites More sharing options...
Wolfehunt Posted September 2, 2022 Author Share Posted September 2, 2022 The magnificent 7. These range from 2 5/8 up to the current world record holder (upper center row) for a modern great white 2 3/4 inches Link to comment Share on other sites More sharing options...
