Archaeologists have identified a roughly 500,000-year-old elephant bone hammer in southern England, marking the oldest known elephant bone tool ever discovered in Europe. Researchers from UCL and the Natural History Museum in London analyzed the artifact, concluding early humans used it to sharpen stone handaxes.
Prehistoric stone toolmaking relied on precision, and a newly analyzed fossilized artifact from southern England shows early human ancestors possessed advanced techniques for maintaining their implements. Recovered at the Boxgrove archaeological site near Chichester in West Sussex, the roughly 500,000-year-old object represents the oldest known elephant bone tool ever discovered in Europe. Researchers from University College London and the Natural History Museum, London, published their findings in Science Advances, pointing to a sophisticated understanding of durable materials among early Neanderthals or Homo heidelbergensis.
Microscopic Analysis Reveals a Prehistoric Retoucher
The fossilized fragment measures approximately 11 centimeters long, six centimeters wide, and about three centimeters thick. Composed mostly of dense cortical bone from an elephant or mammoth, the object sat unrecognized in museum collections after initial recovery during the early 1990s. Its true function only emerged when scientists applied 3D scanning technology and electron microscopes to examine surface marks.
Those scans exposed tiny flint fragments lodged inside impact notches, proving the bone served as a softer striking tool rather than a heavy bludgeon. Archaeologists classified the artifact as a retoucher, an implement used to knock small flakes off worn stone handaxes to restore their cutting edges. Because bone is softer than flint, it allowed ancient knappers to shape and sharpen cutting tools with greater precision.
“This remarkable discovery showcases the ingenuity and resourcefulness of our ancient ancestors. They possessed, not only a deep knowledge of the local materials around them, but also a sophisticated understanding of how to craft highly refined stone tools. Elephant bone would have been a rare but highly useful resource, and it’s likely this was a tool of considerable value.”

Value and Resourcefulness in Paleolithic Britain
Elephants and mammoths were uncommon in prehistoric southern England, making large skeletal fragments scarce and valuable commodities. The decision to preserve, shape, and reuse such heavy bone highlights advanced cognitive planning among early regional populations. Instead of discarding the dense outer tissue as waste, ancient craftspeople recognized its durability under repeated impacts.
“Our ancient ancestors were sophisticated in their use of tools. 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. They were resourceful gatherers of available materials, and savvy about how best to use them.”

While the Boxgrove excavations have previously yielded extensive quantities of flint, bone, and antler artifacts, no tool made from elephant bone had been identified at the site prior to this analysis. Researchers remain uncertain whether the animal was actively hunted or scavenged from an already deceased carcass.
Dietary Evolution and Prehistoric Tool Technology
The emergence of stone tool use roughly 2.5 million years ago by Homo habilis transformed hominid dietary habits and migration patterns. According to Emanuela Cristiani, an archaeologist based at the Diet and Ancient Technology Laboratory in Italy, early scavenging gave way to active hunting supported by cooperative social structures and improved stone implements.
Controlled use of fire further reduced the metabolic energy required for digestion, freeing up resources for brain development. Project findings from researchers investigating hardened dental calculus and ancient tool residues show that prehistoric societies across Europe consumed diverse diets featuring wild cereals, tubers, and grains alongside animal proteins.
