A Buried Grave is the result of using a shovel on a player's remains. It will disappear after 60 minutes unless marked with a flat rock, forming a marked grave. Although the decay rate for buried grave is twice as fast as a Bone Pile, it is inadvisable to bury every skeleton, since it wastes a lot of shovel uses. However, burying beloved family members is generally acceptable, and all other skeletons are usually moved out of the way to the edge of villages to decay as bone piles.
Note: Bones can only be buried on bare ground and cannot be dug on floors or roads.
