How about getting her a unique piece of fossilized jewelry? There are many options out there, such as necklaces or earrings made with ammonite fossils, trilobites, or even dinosaur bone. Or, you could consider giving her a collection of assorted fossils to add to her collection. Another idea could be to take her on a trip to a location known for having great fossil finds, such as the Badlands of South Dakota or the Rivers of the Peace in British Columbia, Canada.
Or you can get her a star map with the date of your anniversary.
