There are multiple ways to obtain Miraculous Fossil Rocks:
- You are gifted a Miraculous Fossil Rock by Minister Pomposa while progressing through the main story.
- They can be found, rarely, at any dig site if you sonar is fully upgraded.
- They can be purchased for 2,500 DP and, very rarely, at the Shop for 250,000 G.
- If you manage to help Gregg Cooke and get 10 seconds exactly, you will receive one.
- If you complete Robo-Don's puzzle without a single mistake, you receive one.
- The 100th fossil cleaned via the Hare Club will wield one as a reward.
Every 20 dropping fossils given to John Guano will wield the reward of one.
Though it is possible to find a Miraculous Fossil Rock without any technique, this is highly improbable- it is best to wear a specific colored mask to a dig site where fossils of that color are not present, such as a Red Mask to Icegrip Plateau. Another technique, though less effective, is to wear a Head Mask to any dig site. You chances of finding a Miraculous fossil rock will improve slightly, as all Miraculous Fossil Rocks contain a Gold Head Fossil.
Note: They are somewhat difficult to find on you're own without said technique above.
