Blombos Cave is a cave in a calcarenite limestone cliff on the Southern Cape coast in South Africa. It is an archaeological site made famous by the discovery of 75,000-year-old pieces of ochre engraved with abstract designs and beads made from Nassarius shells, and c. 80,000-year-old bone tools. Some of the earliest evidence for shellfishing and possibly fishing has been discovered at the site and dates to c. 140,000 years ago.
