High-resolution microCT sections through the lower jaws of three monkeys with different diets and feeding habits (common marmoset, saddle-back tamarin, and squirrel monkey) taken at the level of M/1 of the marmoset jaw on the left. Such images can be used for analyzing the mechanical properties of jaws. See Vinyard and Ryan (2006) for details.
