@sonapville If the individual in that photo is alive, it's doubtful that its age is known. Determining age generally requires a necropsy. A 2016 study using radiocarbon testing did estimate age range of a particular deceased individual to be 392 ± 120 yea
@eliehonig @benjaminwittes Non-jokey answer: researchers radiocarbon dated the eye lens nuclei of 28 by-catch Greenland sharks. Unclear if the photo from the PI is of a specific shark dated to that age per se. https://t.co/uMCjKsFNdv and the paper: https:
