Finding Ancient Bone in Palworld is rather tricky if you haven't clocked that each of the three ancient materials come from the wildlife sanctuaries dotted around the islands. These areas are easy to recognise because of the big shield domes protecting them, but that does mean you have to sneak about and avoid their protectors while doing your illicit mining.
Only one of these sanctuaries contains Ancient Bone, though, so you'll have to head there if you want to craft the fancy accessories that require it.
