This is a compilation of papers devoted to diverse archaeozoological issues. Most of the contributions are based on lectures given at the Seminario Relaciones Hombre-Fauna (Human - Fauna Relationships Seminar) organized by the Laboratorio de Arqueozoologa and sponsored by the Instituto Nacional de Antropologa e Historia, the Mexican federal agency at charge of preserving the palaeontological, anthropological and historical heritages of the country.
