The mammoth diet of Neanderthals

Stable isotope evidence from three Belgian sites

Attempts to gain insight into Neanderthal diet have been many and various over the years. Methods have included consideration of dental microwear, tooth calculus, lithic use-wear and residues, and stable carbon and nitrogen isotope data. These studies have shown that the Neanderthal diet included the consumption of large herbivores, but the extent to which smaller mammals, birds, riverine and seafood was eaten remains uncertain.

To address these issues, researchers conducted carbon and nitrogen stable isotope analyses of collagen extracted from Neanderthal remains from the Belgian sites of Goyet and Spy. Results were compared with those from extensive faunal remains from Goyet, Spy and a third Belgian site, Scladina. These included mammoth, rhino, horse, reindeer, hyena, wolf, cave bear and cave lions. The proportion of the isotopes carbon-13 and nitrogen-15 reflect an animal’s place in the food chain: the highest levels are found in carnivores.

The results show that Neanderthal isotope levels and hence diet differed from that of any carnivore, indicating that they occupied a distinct ecological niche. The overall data suggested that while predators typically preferred smaller animals such as reindeer and horse, the Neanderthal focus was on large herbivores. Mammoth was the most important source of meat, accounting for around 30 to 40 percent of the Neanderthal diet. Reindeer and rhino accounted for lesser proportions, and plant food for about 20 percent.
