The bone is between 43,000 and 42,000 years old, according to 24 radiocarbon datings. [2] This is far older than the Ishango bone with which it is sometimes confused. Other notched bones are 80,000 years old but it is unclear if the notches are merely decorative or if they bear a functional meaning. [3] The bone has been conjectured to be a ...
The Ishango bone on exhibition at the Royal Belgian Institute of Natural Sciences. The Ishango bone, discovered at the "Fisherman Settlement" of Ishango in the Democratic Republic of the Congo, is a bone tool and possible mathematical device that dates to the Upper Paleolithic era. [1]
Border Cave's remains include human remains, lithics, bone tools, botanical remains (i.e. grass bedding) and animal bones. [ 7 ] [ 8 ] [ 4 ] Border Cave's long occupational sequence makes the site an important location for studying prehistoric hunter-gatherer behavior and the causes and timing of the Middle to Later Stone Age transition.

Dated to the Aurignacian, approximately 30,000 years ago, the bone is marked with 55 marks which some believe to be tally marks. The head of an ivory Venus figurine was excavated close to the bone. [2] [3] The Ishango bone is a bone tool, dated to the Upper Palaeolithic era, around 18,000 to 20,000 BC. It is a dark brown length of bone.
The bone has been dated to 42,000 years ago. [12] According to The Universal Book of Mathematics,: p. 184 the Lebombo bone's 29 notches suggest that "it may have been used as a lunar phase counter, in which case African women may have been the first mathematicians, because keeping track of menstrual cycles requires a lunar calendar."
The oldest tally sticks date to between 35,000 and 25,000 years ago, in the form of notched bones found in the context of the European Aurignacian to Gravettian and in Africa's Late Stone Age. The so-called Wolf bone is a prehistoric artifact discovered in 1937 in Czechoslovakia during excavations at Dolní Věstonice, Moravia, led by Karl Absolon.
Ancestors of the Khoisan may have expanded from East Africa or Central Africa into Southern Africa before 150,000 BP, possibly as early as before 260,000 BP. [2] [3] Due to their early expansion and separation, ancestors of the Khoisan may have been the largest population among anatomically modern humans, from their early separation before 150,000 BP until the Out of Africa migration in 70,000 BP.
Homo sapiens, or modern humans, created bone tools and backed blades around 90,000 to 60,000 years ago, in southern and eastern Africa. The use of bone tools and backed blades eventually became characteristic of Later Stone Age tool industries. [3] The first appearance of abstract art is during the Middle Stone Age, however.
