The course is designed to show the scientific, museologic and economic value of the most important fossil groups. The aims of the course are achieved by describing the frequency of fossils in the field, the difficulties on their search and extraction from the rock, and the technical approach to their preparation in laboratory. The course includes also three special sections: on vertebrates and invertebrates, and a last one in which some solutions of Museographical paleontology realized in the Milano Natural History Museum will be illustrated.
Expected learning outcomes
