According to Wikipedia the Lebombo bone (age 35 KY) and the Ishango bone (age at least 20 KY) presently are believed to show the first evidence for application of mathematics by humans. (Possibly African women, constructing a moon calendar, were the first mathematicians.) Is this the present state of the art? Or are there newer discoveries of older mathematical artifacts?
Remark: This question is not asking for some examples but for the present state of historical research in paleo-mathematics.
