Neanderthals did more than hunt massive Ice Age rhinos – they turned the animals’ sturdy teeth into essential workshop tools. Recent analysis of fossilized teeth from caves in Spain and France reveals wear patterns consistent with repeated use in shaping stone implements. This discovery highlights the ingenuity of these ancient hominins, challenging long-held views of their technological capabilities.[1][2]
Traces Uncovered at Iconic Caves
Archaeologists examined rhino teeth from a dozen Middle Paleolithic sites across Spain and France, but two locations stood out for their concentrations of modified specimens. At El Castillo cave in northern Spain, researchers recovered 202 teeth, with 25 bearing distinctive use marks. Pech-de-l’Azé II in France yielded additional examples from the same period, when narrow-nosed rhinoceroses (Stephanorhinus hemitoechus) roamed Europe around 100,000 years ago.[1]
These rhinos, now extinct for roughly 40,000 years, left behind molars weighing up to 380 grams – ideal for heavy-duty tasks due to their hardness and flat surfaces. Neanderthals appeared to select teeth from older animals, favoring those with broader, more stable platforms. Such selectivity points to deliberate planning in their daily survival strategies.[2]
Deciphering the Marks Through Science
A multidisciplinary team applied taphonomic studies to rule out natural damage from chewing, predation, or post-depositional wear. Traceological analysis under microscopes revealed grooves, notches, sliding marks, and scrapes – patterns absent on unmodified prehistoric rhino teeth held at Paris’ Muséum National d’Histoire Naturelle. To test their origins, researchers conducted controlled experiments using modern rhino teeth sourced from French zoos.[1][2]
In these recreations, the teeth served effectively as retouchers, soft hammers, and anvils during stone knapping and material processing. The resulting damage – scaled areas, pitting, fractures, and linear striations – mirrored the ancient specimens almost exactly. Lead researcher Alicia Sanz-Royo of the University of Aberdeen noted, “I had never found teeth with these types of marks. At first, I was quite skeptical.”[1]
Versatile Tools in the Neanderthal Kit
The enamel proved too brittle for direct knapping but excelled in indirect roles, such as striking flakes from stone cores or supporting cuts on fibers and hides. Neanderthals likely held the teeth in hand or fixed them in place, leveraging their durability for repetitive impacts. This expanded toolkit went beyond common bone and antler implements, incorporating superhard dental material for precision work.[1]
- Recurrent notches from hammering actions
- Scaled and pitted surfaces from friction
- Sliding marks indicating guided pressure
- Fresh fractures consistent with overload
Overall, 281 teeth from the two key sites contributed to this picture, underscoring a practical exploitation of faunal remains after consumption.[2]
“This study is important because it opens the possibility that, in addition to bones and antlers, teeth – which are a superhard material – were also very useful.”

Signs of Sophisticated Behavior Across Eurasia
Stashes of rhino teeth appear at other Neanderthal occupations, from La Caune de l’Arago in France to Panxian Dadong in China, suggesting a widespread practice. Archaeologist José Ramos-Muñoz of the University of Cadiz, who was not involved, observed, “This study shows that [Neanderthals] not only ate the animals, but they utilized their remains for their technology. It’s a trait of modernity.” Such resourcefulness reframes Neanderthals as innovative artisans rather than mere survivors.[1][2]
These findings, detailed in the Journal of Human Evolution, build on evidence of Neanderthal adaptability in diverse environments. They prompt questions about how far their technical expertise extended, potentially overlapping with early modern humans in Europe.
As excavations continue, each modified tooth peels back another layer of Neanderthal life, revealing a species more akin to us than once imagined. Their workshops, lit by firelight in deep caves, echo the workshops of today – places where necessity sparked lasting invention.
