> Through an analysis of naturally occurring markings on the juvenile’s first left upper molar, Rosas and his coauthors concluded that the child had almost certainly died between the ages of 7.61 and 7.78 years. That seems remarkably precise. What is it about the molar that allows that level of precision?

  Both of those links are about using the third molar. Is that the same as the "first left upper molar"?

    The third molars are the wisdom teeth. The first molar grows around 6 years of age. At 7-8, kids only have the four first molars (molars only grow once, no tooth fairy for them).

      Makes sense. Any links relevant to how they can be so precise using the first molar?

I came here to post the exact same quote, with the same question. I also know some kids who would like to cheekily answer "how old are you" with that precision.

No one can prove them wrong.
