While sorting through animal bones in a rock shelter in Queensland, Australia, archaeologists came across a tooth where something was "not quite right." Stuck to the tip of its root was a blackish-brown ball of glue-like resin. Eleven more teeth with the same sticky substance were found, making them the only known instance of this type of tooth ornament found outside burials in northeastern Australia and the first in the Cape York Peninsula (CYP), the new study published in Australian Archaeology reports.
