Deciduous teeth.

Baby teeth.

Two of them, from what turned out to be two different individuals.

The genetic work published in 2019 would establish that both were boys, based on DNA from the X and Y chromosomes recovered from the tooth material.

They were not the same child.

They were two boys who had both shed a tooth at this site, in this place, during the same approximate period.

Deciduous teeth are shed between childhood and early adolescence.
