Premaxillae approximated, and right premaxilla with an angular process near base of rostrum overlapping mesirostral ossification.
The proximal extremity of the left premaxillais lacking and also the tip of the beak.
Right premaxilla remains low and concave proximally, the posterior end being then abruptly turned upward and reaching level of vertex.
Right premaxilla on a line with maxillary notches strongly concave and sunk below level of maxillae.
Entirely similar to two preceding, but premaxillae a little curved out from mesirostral ossification and left premaxilla opposite maxillary notch rather strongly inclined, nearly vertical.
Right premaxilla in front of nares broad, flat, and horizontal; left, nearly so, but with a quite broad longitudinal groove.
Nasal bones very small, and widely separated from the premaxilla (which encloses the nostrils) by the maxillaries which join each other for a long distance along the dorsal mid-line.
Nasal bones long, so as to be in contact with the premaxilla at the hinder corner of the nostril groove.
These animals have the frontomaxillary suture and extension of the premaxilla as in D.
The anterior part of this suture lies in a strong ridge, which is continued downwards and forwards on the premaxilla to the level of the fifth tooth, a groove separating it from the margin of the nasal aperture.
The two anterior mandibular teeth are received into pits in the premaxilla; but the canines pass into grooves (which may be converted into fossae) situated at the junction of the premaxilla and maxilla.
The premaxilla is rudimentary and loosely attached to the maxilla.
The premaxilla is well developed, and firmly attached to the maxilla; and there is always a perforation, or foramen, on the inner side of the lower end of the humerus.
Body of the premaxilla pointed and slightly decurved; its length and breadth less than the basis cranii.
Length ofpremaxilla less than two-and-a-half times that of the basis cranii.
A horse is represented in the collection by an upper molar, a fragment of premaxilla with two incisors, an imperfect atlas and two well-preserved hoofs apparently of a foetus or perhaps of a newly-born animal.
The premaxilla is a relatively weak bone in Bombycilla and Phainopepla, stronger in Ptilogonys, and is notably heavy in Phainoptila and Dulus, and in these latter two genera shows a sharply-ridged tomium.
The premaxilla and maxilla of Phainoptila are similar to the same bones in Dulus, and there is a well-marked ridge on the tomium (possibly for cutting flower parts).
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "premaxilla" in a variety of sentences. We hope that you will now be able to make sentences using this word. Other words: chaps; chops; gab; jaw; jaws; jowl; lips; mandibles; maw; mouth; mug; mush; muzzle; trap
