Editing Nasal bone (section)

==Other animals==
In primitive [[Osteichthyes|bony fish]] and [[tetrapod]]s, the nasal bones are the most anterior of a set of four paired bones forming the [[skull roof|roof of the skull]], being followed in sequence by the frontals, the [[parietal bone|parietal]]s, and the [[Postparietal|postparietals]]. Their form in living species is highly variable, depending on the shape of the head, but they generally form the roof of the snout or beak, running from the nostrils to a position short of the orbits. In most animals, they are generally therefore proportionally larger than in humans or great apes, because of the shortened faces of the latter. [[Turtle]]s, unusually, lack nasal bones, with the [[prefrontal bone]]s of the orbit reaching all the way to the nostrils.<ref name=VB>{{cite book |author=Romer, Alfred Sherwood|author2=Parsons, Thomas S.|year=1977 |title=The Vertebrate Body |publisher=Holt-Saunders International |location= Philadelphia, PA|pages= 217–241|isbn= 0-03-910284-X}}</ref>
