Archaeologists have identified a prehistoric hammer made from elephant bone dating back approximately 500,000 years at the Boxgrove site in West Sussex, England, according to researchers from UCL and the Natural History Museum, London. Published in Science Advances, the discovery represents the oldest known elephant bone tool ever unearthed in Europe, pushing back the timeline of advanced bone technology on the continent.
Uncovering a 500,000-Year-Old Prehistoric Hammer at Boxgrove
The fossilized artifact measures roughly 11 centimeters long, six centimeters wide, and three centimeters thick, featuring a distinct triangular shape. According to the research team, early humans—likely early Neanderthals or Homo heidelbergensis—deliberately shaped the cortical bone, the dense outer tissue of an elephant or mammoth skeleton. The fragment was originally recovered during excavations at the Boxgrove site in the early 1990s, but its true purpose remained unrecognized until recent technological examinations.
“This remarkable discovery showcases the ingenuity and resourcefulness of our ancient ancestors,” said lead author Simon Parfitt of the UCL Institute of Archaeology and a Scientific Associate at the Natural History Museum.
Microscopic Clues and Flint Residue Reveal Tool Function
Advanced analysis using 3D scanning technology and electron microscopes allowed researchers to examine the surface of the bone for microscopic wear patterns. According to the study, the team identified distinctive notches and impact damage indicating repeated use as a retoucher. Tiny pieces of flint found lodged inside the surface marks provided direct physical evidence that the bone served as a “retoucher,” a specialized tool used to strike and sharpen the edges of worn stone handaxes.
Because elephants and mammoths were uncommon in prehistoric southern England, acquiring and preserving such dense skeletal material required deliberate planning. Co-author Dr. Silvia Bello, a Merit Researcher at the Natural History Museum, noted that the artifact demonstrates complex cognitive abilities. “Collecting and shaping an elephant bone fragment and then using it on multiple occasions to shape and sharpen stone tools shows an advanced level of complex thinking and abstract thought,” she stated.
Comparing European and Global Early Bone Technology
Before this analysis, no European elephant bone tool was known to predate approximately 450,000 years, and those rare examples originated primarily in warmer southern climates. By contrast, much older elephant bone tools dating back 1.5 million years have been documented at Olduvai Gorge in Tanzania. The Boxgrove discovery expands both the geographical range and the known chronology of early bone technology in northern Europe, illustrating that British hominins utilized specialized resources long before modern humans (Homo sapiens) spread across the continent around 43,000 years ago.
Did You Know? The Boxgrove site in West Sussex is one of the most thoroughly excavated Lower Paleolithic sites in the world, having yielded numerous flint handaxes alongside preserved animal remains.
