Yeah, I'm sure the Tongan royal family was like "James Cook" take this tortoise and then they just kept in a Tongan zoo all this time, carefully keeping track of its age for almost 200 years.pic.twitter.com/wFVjV2V0sP

I'm pretty skeptical that there are vertebrates that live 200+ years. All the longest living giant galapagos tortoises conk at ~150 years old and they all have very shady origin stories for how they got to the zoo.pic.twitter.com/eeFbEGpfVi

I also don't believe that Jeanne Calment made it to 122. Too much of an outlier. Human longevity does not have fat tails, only human records of it do!pic.twitter.com/TPxEQsCXmk

From the sharks paper (screenshot). "Von Bertalanffy" is a method to link age with size, as far as wiki says. Basically they used size to train a model which as been tested with sharks from post-WW2, as far as I understand. Seems a bit circular, after assuming size predicts agepic.twitter.com/iRszPV3B8d

(That said it's almost midnight, I know nothing about the topic, and I just quickly skimmed the paper on scihub out of mere curiosity, so I put a low confidence on the above, and would love to hear what others think.)

Is there a more scientific way to determine a living specimen age other than historical bookkeeping? Something more analogous to carbon dating?

Yes, in that screenshot actually you see that they did something like that with the eye of the shark. There could be some peculiarities about the eyes of those animals though that would prevent this from being accurate.
