The |parietal bones| form the two sides and much of the top of the newborn |skull|. The |parietal bones| of the neworn each feature a bulbous ~tuberosity~.

As the newborn grows, the |skull| wil begin to lose this ~tuberosity~ and the |parietal bones| will become more even on the sides of the |skull|.
