You have to date the volcanic layer above and below the fossil layer.The layers on top could only be laid down on top of the bottom layer so must be younger.However the relative ages of rocks is more commonly determined by the presumed ages of the fossils found in the sedimentary layers.The relative dating is the technique in the Geology through which the age is determined with relation to the other objects.
In other words, we can say that in relative dating the archaeologist determines that which of the two fossil or the artifacts are older.We can absolute date materials but it will always have an uncertainty range, we can never know the age with infinite precision.
