From: Enamel apatite crystallinity significantly contributes to mammalian dental adaptations

Computed volumes of enamel HAp crystallites of (a) miniature pigs. For comparison of changes in crystallite volume with age, the volumes are plotted against the age of each individual. The solid black lines are the average volume for each molar type and the colored areas show a dispersion of data set (1 σ). Each point in the plot (b) represents the average HAp crystallite volume of individual molar types of red deer.
