    I would love to see any deformed/pathologic Megalodon teeth you’ve found and hear your thoughts on what might have caused them!

    Yes Teddy @teddy-badaut, it is definitely worth publishing it … with some improvements.
    I look forward to work on it with you.

    cheers

    Hey Teddy @teddy-badaut, I have talked to Victor and we would like to work on that together. I will figure out what is needed and will get back to you soon.

    • Hey Ronny @rleder  I’m glad to learn this ! Do you think it could be worth a paper or an article ? Meanwhile I keep gathering some data (as much as I can at my level). I’m sending you through email another figure showing directly the discrepancy in the dentition size.
      Best,

      Ted

    • Very well ! Yes I certainly expect improvements and additional datas. I’ve found some methods using bite marks size to estimate the size of the shark but they don’t seem adapted on associated dentitions without actual jaws structure since they take into account interdental spacing and actual curvature of the dentition in the calculation. Hence…[Read more]

    Hey Teddy @teddy-badaut,
    thanks for your paper, very interesting! Maybe we can find a way to work on that with more tooth sets (also with some carcharinid sets as extra control group) and publish it. Would be great. With your consent (?) I would like to discuss this with Victor tomorrow and get back to you.

    all the best

    Ronny

    • @rleder  Ronny,
      Thank you, you welcome ! I’d be very glad and proud that it results at the end in a publication. Certainly more data from others sets would be needed and I guess more summed dentitions measurements from white sharks individuals with known TL.
      Of course you can discuss this with Victor, actually we already had discussed earlier…[Read more]

    Hey Teddy @teddy-badaut,

    yes you are right Gottfried et al. simply scaled C. megalodon using isolated anterior teeth and estimated TBL based on the proportions of C. carcharias. I agree with you that using the dentition size might result in much better estimates than using just single teeth (just think about what Victor mentioned about his…[Read more]

    • Hey Ronny @rleder ,

      Thank you for the kind words. I think that using dentition size for fossil macropredatory lamniforms has been already proposed a few times but I’ve always found strange that no one already had the idea to perform TL extrapolations from the available sets, though thinking about it I guess one of the reason was that they are…[Read more]

    Hello Teddy @teddy-badaut,

    thank you for your interesting comment. Actually that was something scientists have already tried (Masey, Gottfried, Compagno & Bowman etc.) but the problem is that the proportions might be very hard to estimate. The shark can have a proportional very large or very small jaw compared to the body size.

    all the best
