When i first got the game i couldnt even mine up minirles it was 1/10 that i dug up. so i made it easyer by dotting.
Step 1:find minirle,fossil,cube or rarae stone.
Step 1 1/2:ghet rid off sludge lava water ice (not alwayts required)
Step 2:put scan on and make a circle around the item (best used for new finds of fossils)
Step3:tap your styls on the area where the item is until its seeable(allways tap at different spots becaus when you touch an area the is already exposed it will become damaged)
Step 4:be as quick and careful as you can.
Step 5:pick it up or (for a crowned fossil aqnd perfect diggind skill points )get it to 100%
