Hydroxy lapatite

C values of carbonate hydroxylapatite range from -148 to -10.3%o in herbivores. They range from -17.4 to -15.4%o in bears, and from -16.1%o to -14.5 in carnivores (Table 4.1). The average values clearly differ between herbivores (-12.7 1.4%o), bears (-16.2 0.6%o) and carnivores (-15.5 0,6%o). The 5 C values of carbonate hydroxy lapatite of bears are slightly more negative than those of other carnivores.
