In humans: bone forming side and roof of cranium. Each bone is irregularly quadrilateral in form, and has two surfaces, four borders, and four angles. [ ZFA:0000514 http://en.wikipedia.org/wiki/Parietal_bone ]

homology notes

The homologization of cranial bones of actinopterygians with those of sarcopterygians based on the bone names established in human anatomy is favored in order to permit the building of phylogenetic relationship schemes beyond the taxonomic boundaries of osteichthyans (including tetrapods). (...) In actinopterygians, the terms parietal and postparietal bones have to replace the commonly used terms 'frontal' and 'parietal' bones for the two paired bones on the skull roof.[well established][VHOG]

taxon notes

The frontal bone in teleost fish is the homolog of the parietal bone in tetrapods[various]. In many non-mammalian tetrapods, they are bordered to the rear by a pair of postparietal bones that may be solely in the roof of the skull, or slope downwards to contribute to the back of the skull, depending on the species. In the living tuatara, and many fossil species, a small opening, the parietal foramen, lies between the two parietal bones. This opening is the location of a third eye in the midline of the skull, which is much smaller than the two main eyes
