Posterior to the four premaxillary
teeth there is a diastema as long as the mesiodistal length of an alveolus where the fourth large dentary tooth is accommodated.
All the studied specimens present the holorhinal condition of the nostril, and in general, present narrow nostrils, premaxillary
strongly fused to the nasal, and both entirely calcified.
The area in front of maxillary line is the premaxillary
line or lacrimal sac area.
Anterolaterally, the mass was causing destruction of the anterior root of the zygoma with extension into the premaxillary

cleft," Journal of Oral and Maxillofacial Surgery, vol.
These are the maxillary, premaxillary
and dentary bones.
Banded Darter are a moderately slender darter with a broadly connected gill cover, premaxillary
frenum connecting snout to the upper lip, and complete lateral line (Smith, 1979; Robinson and Buchanan, 1988; Pflieger, 1997).
Teeth distinctly developed, in a single row and forked in fish over about 50 mm SL; Five to eight scales between the dorsal fins; protruded upper jaw (premaxillary
bones) extends forward rather than downward; body deeper, depth 4 to 6 times in SL ...
shape and dental microwear analyses showed that the diets of extinct Giraffidae were highly heterogeneous (e.g.) the Bramatherium megacephalum (Lydekker 1878) and Sivatherium giganteum Falconer and Cautley 1835 (Sivatheriinae) were grazers.
Synaphobranchus oregoni has large teeth on the anterior end of the vomer that are nearly the same length as the premaxillary
teeth (Sulak and Shcherbachev 1997:1171, fig.
