You're supposed to get 4 new fossils every day, right? And I assume no more spawn if you haven't dug up one from a previous day? Except, I'm only getting 3 a day now. I don't think I'm missing any because I ran the length of my town multiple times over the length of a few days, and the stars are really easy to spot most of the time. Is it possible for fossils to spawn in a place you can't reach them? Or am I just blind? Any tips on where to look if I am just blind?
I'm starting to find mostly repeats of fossils I've already found and my villagers say things like "This place is shaping up!" about my fossil exhibit, so I don't even look that hard for them anymore. With how long I know I'll be playing this game, I know I'll definitely find them all eventually, so I'm just not that worried about it. xD Maybe it will end up being the same way for you!
