Wouldn't it be cool if we came up with fossils and artifacts while gathering? We could come up with different types of items depending on the thing we're harvesting. If we're mining, perhaps we could find fossils of proto-chickens. If we're digging in peat bogs or dirt piles, we could find artifacts of proto-Glitchian society (smaller than the statuary we see now and again).
Perhaps a skill called Archaeology would give us the means to put pieces together to form a whole item (and give us better chances of finding pieces).
