Paired dermal bones, likened to a bone tube, positioned lateral to the supraethmoid. Nasal bones are transversed by the anterior most part of the supraorbital canals and bear one neuromast foramen in zebrafish[ZFA].

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. Turtles, unusually, lack nasal bones, with the prefrontal bones of the orbit reaching all the way to the nostrils (ISBN 0-03-910284-X) TAO:0000365 UBERON:0001681 SCTID:181801008 relationship loss: part_of braincase and otic capsule skeleton (AAO:0000052)[AAO] MA:0001494 VHOG:0001370 Wikipedia:Nasal_bone nasal bone nasals intramembranous bone skeleton splanchnocranium flat bone
