The Lebombo bone is an archaeological artifact that consists of a baboon fibula with 29 distinct notches. It was discovered in the Lebombo Mountains, which lie on the border between South Africa and Swaziland (now Eswatini). The bone is estimated to be around 35,000 to 65,000 years old and is thought to be one of the oldest known counting tools.
