The Lebombo bone, the oldest known mathematical artifact, is a tally stick with 29 distinct notches that were deliberately cut into a baboon's fibula. It was discovered within the Border Cave in the Lebombo Mountains of Swaziland.

The Lebombo bone resembles the calendar sticks still used by Bushmen in Namibia.
