First of all, the sources of fossils: fishing, planing, panning for gold, bone ore, smashing open the golden coconut
Special points: frog fossil is mowing the grass, bat fossil is ginger island volcano to fight monsters.
Snake fossils: snake heads have a high shipment rate when fishing in the river on the farm! I've caught up, 3 heads in one night! Spines found while digging in the farm.
Bear:
Pawpaw: bone ore.
Tail, Spine, Belly: digging elsewhere on the island, panning for gold in the Bone Mine river.
Head: open the golden coconut, the golden coconut is digging the ground, shaking the coconut tree can come out, the probability is not high or low. Sometimes good luck a hoe can dig 4 gold coconut. Then go back to Pelican Town to open
I think it's pretty good to find.
