The fossil consists of a single partial left maxilla, an upper jaw bone, with seven teeth.

They lost the upper jaw bones completely.

Maxillary means "related to the maxilla (upper jaw bone)".

Patients may also have an underdeveloped upper jaw bone, abnormally prominent brows, or widely spaced eyes.

It has 5-6 maxillary (upper jaw bone) teeth behind fangs and 2 anterior temporals.

These bones form part of the main upper jaw bone or maxilla, which converge in the middle to form a pair of prongs.

The tall premaxilla (frontmost upper jaw bone), which made the tip of the snout very blunt, was also typical of the family.

The lower jaw bone is called the mandible and the upper jaw bone is called the maxilla.

The upper jaw bones of rauisuchians are not closely connected, leaving a small opening between the premaxilla and maxilla that is not seen in Smok.

Baldwinonus trux is known from a fragment of a right maxilla or upper jaw bone, part of a quadrate bone, and several vertebrae.

While the stapes is present in all tetrapods, the malleus and incus evolved from lower and upper jaw bones present in reptiles.

The holotype, or original specimen, consists of only a maxilla (upper jaw bone), and a dentary (lower jaw bone), both from the left side of the same individual.

Unique skull features included the rough outer surface of the maxilla (upper jaw bone) and the pronounced crests around the eyes on the lacrimal, postorbital, and jugal bones.

In 1860, Sixt Friedrich Jakob von Kapff at the Heslacher Wand near Stuttgart discovered the upper jaw bone of a large reptile.

Rugosuchus (meaning "uneven or wrinkled crocodile", in reference to texturing on its upper jaw bones) is an extinct genus of neosuchian crocodyliform from the late Early Cretaceous of China.

The two share several skull details, among which a large maxillary fenestra - an opening in the maxilla, an upper jaw bone - and lack various features of more derived dromaeosaurids such as Velociraptor.

A large gap, called a diastema, separated the premaxillary teeth from the those of the maxilla (the main upper jaw bone) in many ornithischia, but this diastema was arched in heterodontosaurs.

The shoal bass has scales on the base portion of the soft-rayed dorsal fins, clearly connected first and second dorsal fins, and an upper jaw bone that does not extend beyond the eyes.

Among the most prominent of these derived features (apomorphies) is the way the upper jaw bones are connected (the premaxilla-maxilla articulation), which is flexible with a deep gap between the teeth in the two bones.

Tangle nets - also known as tooth nets, are similar to gillnets except they have a smaller mesh size designed to catch fish by the teeth or upper jaw bone instead of by the gills.

The outside surface of the maxilla (upper jaw bone) and the upper surface of the nasal bone on the roof of the snout were not nearly as rough-textured as those of Giganotosaurus or Carcharodontosaurus.

Concavispina can be differentiated from other thalattosaurs by possessing two rows of blunt teeth on the anterior part of the maxilla (upper jaw bone) and a V-shaped notch on the dorsal margin of each neural spine in the dorsal (back) vertebrae.

A maxillary sinus floor augmentation procedure (sometimes known informally as a sinus-lift or sinus procedure) is a surgical procedure performed by an appropriately trained dentist or dental specialist to increase the amount of bone in the posterior maxilla, or upper jaw bone.

Most of the upper jaw bones (premaxilla, maxilla, jugal, quadratojugal, and quadrate) have been fused to the braincase, while the lower jaw bones (dentary, splenial, angular, surangular, and articular) have been fused together into a unit called the mandible.

NHMUK R8646 consists of a right maxilla or upper jaw bone, a left scapula or shoulder blade, part of what might be the ischium bone of the pelvis, five complete and four partial dorsal vertebrae, three caudal vertebrae, and five osteoderms.
