Vomer
in anatomy, a small thin bone in the median line, forming the posterior and principal portion of the partition between the nostrils in man. It exhibits many modifications in the different classes of vertebrata. In fishes an important character is the presence or absence of teeth on the vomer (that is, along the middle line of the roof of the mouth). The bone is so named from the fact that in man it bears some resemblance to a plowshare. In palæontology, a genus of Carangidæ, allied to Caranx, from the Chalk of Comen in Istria.
