Modern rhino teeth used to replicate Neandertal activities showed markings very similar to the fossilized teeth found in the caves. (Sanz-Royo et al.\/Journal of Human Evolution<\/a>)<\/p>\n A Dental Toolkit for the Paleolithic<\/p>\n Archaeologists have long known that Neanderthals repurposed animal remains, such as bones and antlers, as hammers or retouchers to keep their stone tools<\/a> sharp. However, few studies have investigated the potential use of teeth. The research team, led by Alicia Sanz-Royo of the University of Aberdeen, was intrigued by unexpected markings on several teeth. They surveyed a dozen archaeological sites in France and Spain, focusing on El Castillo in Spain and Pech-de-l’Az\u00e9 II in France.<\/p>\n At these sites, researchers found rhinoceros teeth bearing distinct grooves, notches, sliding marks, and scrapes, which strongly suggested repeated hitting and percussive use. Microscopic analysis confirmed that these markings were not caused by chewing or natural taphonomic processes before or after the animal’s death. According to Science News<\/a>, the team identified at least three distinct types of damage patterns consistent with tool use rather than butchering or gnawing.<\/p>\n To test their hypothesis, the researchers conducted controlled archaeological experiments using modern rhino teeth obtained from zoological reserves. They reenacted tasks Neanderthals might have regularly performed, such as using the teeth as soft hammers to sculpt stone tools and as anvils for cutting vegetable fibers and leather.<\/p>\n Bone tools used by Neanderthals, showing the variety of animal-derived implements in their toolkit. (Nature \/ CC BY 4.0<\/a>)\u00a0<\/p>\n The Effectiveness of Rhino Molars<\/p>\n The experiments produced damage on the modern teeth \u2014 specifically scaled areas, pitting, and microfractures \u2014 that closely matched the patterns observed on the fossilized teeth. Despite the significant weight and bulk of the rhino molars, which can weigh up to 380 grams, the experimenters found them surprisingly effective. Larger teeth with flatter surfaces proved the most comfortable to use, providing a stable and durable platform for precision tasks like flint knapping<\/a>.<\/p>\n Based on the types of teeth that bore the marks, the researchers concluded that Neanderthals were selective, choosing teeth with the right size or shape for the job at hand. Interestingly, the majority of the rhino teeth utilized by Neanderthals appear to have been harvested from elderly animals. This may indicate that the teeth of older individuals were more suitable for tool use, possibly because of their flatter, worn surfaces, or it could simply reflect that aging rhinos were easier targets for hunters.<\/p>\n “I had never found teeth with these types of marks. At first, I was quite skeptical,” said Sanz-Royo. “This study is important because it opens the possibility that, in addition to bones and antlers, teeth \u2014 which are a superhard material \u2014 were also very useful.”<\/p>\n Parietal art in the cave at the Castle, Cantabria, Spain, one of the key sites where rhinoceros teeth bearing tool-use marks were found. (Gobierno de Cantabria \/ CC BY 3.0<\/a>)<\/p>\n Expanding Our Understanding of Neanderthal Behavior<\/p>\n The discovery adds a new dimension to our understanding of Neanderthal cognitive complexity<\/a> and resourcefulness. With 202 rhino teeth found at the El Castillo cave alone, 25 of which bore use marks, the findings hint at an intentional behavior that goes beyond mere opportunism. Neanderthals were not just eating these massive herbivores; they were systematically recycling their most durable parts into specialized equipment.<\/p>\n As anthropologists continue to investigate Paleolithic lifestyles, the full extent of Neanderthal cognitive abilities<\/a> remains a subject of intense interest. Researchers are finding increasingly compelling evidence that suggests Neanderthals possessed advanced problem-solving skills and symbolic thought \u2014 traits once considered exclusive to modern humans. Recent discoveries have shown that Neanderthals created art, crafted complex tools, and cared for injured companions<\/a>, painting an ever-richer picture of their inner lives.<\/p>\n “This study shows that [Neandertals] not only ate the animals, but they utilized their remains for their technology,” noted archaeologist Jos\u00e9 Ramos-Mu\u00f1oz of the University of Cadiz, who was not involved in the study. “It’s a trait of modernity.”<\/p>\n The use of rhinoceros teeth alongside bone and antler tools<\/a> highlights a sophisticated approach to raw material exploitation, demonstrating that our extinct cousins were highly adaptable artisans capable of maximizing the resources available in their environment. As more sites are examined with modern analytical techniques, the full scope of Neanderthal technological innovation may prove even more remarkable than current evidence suggests.<\/p>\n Top image: Illustration of the prehistoric narrow-nosed rhinoceros (Stephanorhinus hemitoechus), a species whose teeth were used as tools by Neanderthals.\u00a0 Source: DiBgd\/CC BY-SA 4.0<\/a><\/p>\n By Gary Manners<\/a><\/p>\n References<\/p>\n Barbuzano, J. 2026.
