2. Fossil book - Consider gifting a book that features images of different fossils from all over the world. This can be a great way to expand his knowledge and appreciation of his hobby.
3. Fossil hunting trip - Surprise your dad with a fossil hunting trip or visit to a local museum with a focus on fossils. It could be a fun and memorable experience for him.
4. Fossil-themed accessories - You can also consider getting your dad some fossil-themed accessories. There are a lot of great options out there, including cufflinks, neckties, and even tie clips or watches with fossil designs.
