Ossification begins in the lateral flanges, then in the prevomerine processes, and lastly in the posterior dentigerous parts of the bones; the prevomerine processes are the last parts of the vomers to ossify completely.
After the maxillaries and premaxillaries develop, the vomers appear as small horizontal ossifications anterior to the parasphenoid.
