Bottom Line: To this end, we have analysed fat from several frozen bison found in the permafrost of Siberia (Russia).Fat samples from two bison showed two well-differenced areas, i.e. brown and white, the latter being saturated fatty acid enriched, corresponding to an intermediate stage of adipocere formation, while the brown ones yielded α-linolenic acid in higher percentages than found in present-day bison.As demonstrated in this work, the subcutaneous fat of bison consumed by Mesolithic hunters contained amounts of n-3 fatty acids in higher quantities than those found in current bison; thus, the subcutaneous fat of bison could have contributed to meet today's recommended daily intake of essential fatty acids for good health in the Mesolithic to a greater extent than previously thought.

ABSTRACT
Knowledge concerning the availability of n-3 fatty acids for humans in prehistoric times is highly relevant in order to draw useful conclusions on the healthy dietary habits for present-day humans. To this end, we have analysed fat from several frozen bison found in the permafrost of Siberia (Russia). A total of 3 bison were included in this study, all them very close to the early Holocene (8,000; 8,200; and 9,300 years BP). All samples were analysed by gas-liquid chromatography-mass spectrometry (GLC-MS) and GLC flame-ionization detection (GLC-FID). Fat samples from two bison showed two well-differenced areas, i.e. brown and white, the latter being saturated fatty acid enriched, corresponding to an intermediate stage of adipocere formation, while the brown ones yielded α-linolenic acid in higher percentages than found in present-day bison. As demonstrated in this work, the subcutaneous fat of bison consumed by Mesolithic hunters contained amounts of n-3 fatty acids in higher quantities than those found in current bison; thus, the subcutaneous fat of bison could have contributed to meet today's recommended daily intake of essential fatty acids for good health in the Mesolithic to a greater extent than previously thought.

Bison Yukagir (Bison priscus Bojanus, 1827).This frozen bison was found along the eastern shore of Chukchalakh Lake at an unnamed hill (558 m a.s.l.). The carcass is complete, including snout, ears, tail and genitalia. All organs are fully preserved, including the contents of the digestive tract, as well as the rumen, stomach and intestines.

The carcass is complete, including snout, ears, tail and genitalia. All organs are fully preserved, including the contents of the digestive tract, as well as the rumen, stomach and intestines.

Mentions: A total of 3 specimens of frozen bison (B. priscus) from Siberia (Figure 1) were included in this study (Table 1), i.e. a baby bison from Batagay (bison Batagay), a complete body of an adult male from the Yuka region (bison Yukagir; Figure 2), and a bison from Rauchua river (bison Rauchua), which were very close in time, all from the early Holocene (8,200; 9,300; and 8,000 years BP, respectively78). Permission was received to examine the relevant specimens from museum collections. Samples from the frozen carcass of bison Rauchua were donated by the Ice Age museum in Moscow; baby bison Batagay by the Museum of Mammoth, Institute of applied ecology of the North, North-eastern federal University in Yakutsk; and bison Yukagir from by the Yakutian Academy of Sciences, Yakutsk (all them in Russian Federation).
