In their work, scientists emphasize the Bolahla archaeological site in Lesotho, which dates back to the Stone Age. This site is believed to have been inhabited by the Khoesan and Basotho communities from around 1100-1700 AD. The area is located between a series of hills formed by solid sediment layers trapped beneath a desert resembling the Sahara about 180-200 million years ago, when dinosaurs first roamed the earth.

In 1990, archaeologists in Bolahla discovered the fossilized finger of a Massospondylus that had been transferred into a cave. Although no fossilized skeleton was visible on the cave walls, it is estimated that someone brought the fossil into the cave. The reasons could be diverse, perhaps out of curiosity, to make jewelry or toys, or for traditional healing ceremonies.
