In the Eurasian Upper Paleolithic after about 35,000 years ago,
abstract or depictional images provide evidence for cognitiveabilities
considered integral to modern human behavior. Here wereport on two
abstract representations engraved on pieces of redochre recovered from
the Middle Stone Age layers at Blombos Cavein South Africa. A mean
date of 77,000 years was obtained forthe layers containing the
engraved ochres by thermoluminescencedating of burnt lithics, and the
stratigraphic integrity was confirmedby an optically stimulated
luminescence age of 70,000 years onan overlying dune. These engravings
support the emergence of modernhuman behavior in Africa at least
35,000 years before the startof the Upper Paleolithic.
