Uberon Homology note : In bony fish, the vomers are flattened, paired, bones forming the anterior part of
the roof of the mouth, just behind the premaxillary bones. In many species, they have
teeth, supplementing those in the jaw proper; in some extinct species the teeth on
the vomers were actually larger than the primary set. In amphibians and reptiles,
the vomers become narrower, due to the presence of the enlarged choanae (the inner
part of the nostrils) on either side, and they may extend further back in the jaw.
They are typically small in birds, where they form the upper hind part of the beak,
again being located between the choanae. In mammals, the vomers have become narrower
still, and are fused into a single, vertically oriented bone. The development of the
hard palate beneath the vomer means that the bone is now located in a nasal chamber,
separate from the mouth[WP];
