* Big ammonite fossils are static objects: They are part of the environment and can't be interacted with in the same way you can move smaller fossils.
* You need the right tools: You would typically need a digging tool like a pickaxe or shovel to excavate and move fossils. However, the game mechanics don't allow you to do that with larger fossils.
What you can do:
* Focus on smaller fossils: Instead of trying to move a big ammonite, concentrate on digging up the smaller fossils scattered around the ruins.
* Use your Vivosaurs to break obstacles: If the big ammonite is blocking your path, use the abilities of your Vivosaurs to break it up. Some Vivosaurs have attacks that can destroy rocks and other obstacles.
Remember, the goal in the ruins is to find and collect as many fossils as possible, and that includes the smaller ones. So don't get discouraged if you can't move the big ammonite!
