Fossil Hunting refers to the exploration and collection of the preserved remains or impressions of organisms from prehistoric times encased in rock. It falls under the broader category of collectibles, as fossils are often collected, studied and displayed. Relating to hobbies, it's an outdoor activity enjoyed by many, comparable to the patient, detailed work of cross-stitching. The activity involves careful searching, digging and cleaning, requiring patience and precision similar to that needed in cross-stitching.
