Sorry, no etymologies found.
The skull is often somewhat flattened in the neighborhood of the parietal foramina, and the term obelion is applied to that point of the sagittal suture which is on a level with the foramina.
An additional fontanelle is sometimes seen in the sagittal suture at the region of the obelion.
