Mialet Cave

The 5 N enrichment in dentine collagen relative to bone collagen in species with definite tooth growth is observed in samples from Marillac, Kent s Cavern, Aldene and Mialet caves (Fig. 4.10). The highest 8 N values are measured for deciduous teeth in fossil samples (Bocherens et al. 1994 Fizet et al. 1995). No enrichment is observed between dentine and bone collagen in horses (Bocherens et al. 1995b Fizet et al. 1995). 

Figure 4.7. 5 C and 5 N values of bone collagen from Mialet cave mammals (-35,000 - 60,000 BP) compared with those of recent mammals from cold and temperate areas (average 1 s.d.). Isotopic abundances of Mialet cave mammals are from Bocherens et al. (1994).
