Table 1.   Bone collagen delta 13C and delta 15N values of Neanderthals and associated fauna from Vindija Cave, Croatia

Sample Species Level  delta 13C  delta 15N C:N % Coll. % C % N
Vi-207 Neanderthal G1  -19.5 10.1 3.2 6.5 37.1 13.5
Vi-208 Neanderthal G1  -20.5 10.8 3.6 4.2 36.1 11.7
V1 Bos/Bison spp. G3  -20.4 5.3 3.2 11.4 18.8 6.8
V3 Cervid G1  -20.3 5.2 3.2 16.1 20.4 7.4
V4 Ursus spelaeus G3  -21.1 1.3 3.3 29.1 14.4 5.1
V5 Ursus spelaeus G1  -20.7 1.5 3.3 12.6 18.8 6.7
delta 13C values are measured relative to the Vienna Pee Dee Belemnite standard, and delta 15N values are measured relative to the ambient inhalable reservoir standard. "% Coll." is the mass of freeze-dried "collagen" produced as a percentage of the starting total bone mass. % C and % N are the percent amounts of carbon and nitrogen measured in the mass spectrometer compared with the starting mass of extracted collagen. Measurement errors on the delta 13C values are ±0.3per thousand ; errors on the delta 15N values are ±0.4per thousand .
