Lebombo Bone
Lebombo bone was discovered at Lebombo Mountains near Swaziland. It is aged back to between 44,200 and 43,000 years ago. It is made of two fibula bones of a baboon. It has several marks and incisions on them thought to be used for counting in those days. It is also believed that the women of those days used it to keep track of their monthly periods.
