As a lover of both geometry and antiquity, I am thrilled to share the findings of a recent study on limestone spheroids from the Early Acheulean site of ‘Ubeidiya in Israel, dated to approximately 1.4 million years ago.
Led by Antoine Muller of the Hebrew University of Jerusalem, a team of international researchers analyzed 150 spheroids using innovative 3D scanning and geometric analysis methods.
Spheroids, also known as stone balls, polyhedrons, or bolas, are amongst the oldest surviving lithic tool types, appearing as early as the Oldowan and continuing into the Middle Palaeolithic.
