A transverse bony ridge across the cranium near the posterior border of the parietals
A vacant space, or gap, between teeth
Overlapping as the shingles of a roof
A ridge traversing the top or side of the braincase, marking the dorsal border of the insertion of the temporal muscle. They may be found on parts of the frontal and parietal bones
Teeth with high crowns; usually rootless and ever-growing
Having a fringed or fringe-like border
Having teeth differentiated into various types, i.e. incisors, canines, premolars, and molars
Having perforations or openings
The part at the rear of the mandible that articulates with the upper jaw
Condition that exist in the Paucituberculata and Diprotodonta. The lower jaw is shortened and the first lower incisors are greatly elongated to meet the upper incisors
Pertaining to two or more digits that are fused together
The most dorsal part of the mandible, the part of the vertical ramus dorsal and anterior to the condyle
Bone, if present, located just beneath the auditory bulla
Bone surrounding the middle ear cavity
A bone in the penis of certain mammals
On the side next to the lips
In bats, membrane that fills space between the digits of the forelimb: d. minus (between digits II and III), d. longus (between digits III and IV), d. latus (between digits IV and
The layer of bonelike material covering the root of a tooth
The internal or posterior bony opening(s) of the nasal cavity
An unpaired median bone in the floor of the interpterygoid fossa, with two lateral wings, sometimes called orbitosphenoids, that form part of each orbit
Deciduous teeth, posterior to the canines
Skin membvrane extending between the hindlegs and frequently enclosing the tail - especially in bats
Chamber into which digestive, reproductive and urinary systems empty, and then exit the body
A bony bar between the orbit and the temporal fossa, formed by the union of the two postorbital processes
An unpaired bone at the rear of the cranium located between the parietals and above and anterior to the occipital
The bony external or anterior aperture of the nasal cavity
The lower jaw, composed of the two dentaries in mammals
A passage from the anterior face of the orbit to the side of the rostrum, passing through the base of the maxillary process
A knob on either side of the foramen magnum that articulates with the first vertebra
Extremely hard outer layer on the crown of a tooth. consiting of calcareous compounds
The bone that forms the midsection of the zygomatic arch
Paired bones roofing the posterior part of the braincase
In bats, thin web of skin that extends from the shoulder to the wrist anterior to the upper arm and forearm
A passage through which the tear duct drains into the nasal cavity, usually near the anterior margin of the orbit
The first digit of the pes (foot), the big toe; frequently opposable in arboreal mammals
A small bone in the anterior face of the orbit
The posterior teeth in the upper and lower jaws that are nondeciduous
The bone in the upper jaw that bears the canine, premolar, and molar teeth
A winglike bone forming part of the lateral wall of the braincase. It also forms part of the posterior wall of the orbit. Frequently fused to the basisphenoid
On the side next to the tongue
The bone surrounding the foramen magnum and bearing the occipital condyles. Formed from 4 embryonic elements, the basioccipital below, 2 exoccipitals, and the supraoccipital above
With a pattern consisting of sharply angled triangles, or loops with sharp salient angles
The inflated bony capsule that encases the middle and inner ear
A median ventral bone lying anterior to the occipital and between the auditory bullae
cheek teeth with a cutting or shearing action adapted for a carnivorous diet
A fan-shaped bone on either side of the braincase above the auditory bulla
The arch of bone that forms the lateral border of the orbit and temporal fossa
A thin, median, vertical partition of bone that divides the nasal cavity into right and left halves
A bony or cartilaginous spur arising from the ankle, and in bats, helping to support the uropatagium
An enlarged tooth between the incisors and premolars; usually a large stabbing tooth, occasionally bladelike, but sometimes small and similar to the teeth preceding it
Nipping or chiselling teeth at the front of the jaws
The bony roof of the mouth composed of parts of the premaxillary, maxillary and palatine bones
Teeth with longitudinal crescentic ridges of enamel
Paired bones, sometimes fused to the basisphenoid and alisphenoids, that form the walls of the posterior part of the interpterygoid fossa
A perforation through a bone for the passage of a nerve or blood vessel
Ivory-like substance beneath the enamel, usually constituting he bulk of a tooth
One of the two branches of the mandible
The trough in the squamosal bone for the reception of the mandibular condyle of the dentary
A projection from either the jugal bone on the zygomatic arch, or the frontal bone, partially separating the orbit and the temporal fossa
The projection from the lower medial margin of the pinna in most microchiropteran bats
A hooklike spine on the posyterior cormer of the pterygoid bone
Lacking teeth
External ear
The large space between the orbit enclosed by the zygomatic arch and the postorbital processes
The anterior-most pair of bones covering the brain, situated between the orbits. Actually paired, but often fusing together at an early age
The opening of the skull through which the spinal cord emerges
The posterior ventral projection of the dentary below the condyle
A transverse ridge of enamel across a tooth
The lower jaw bone, constituting one half of the lower jaw or mandible
The bony socket that contains the eyeball
On the side next to the cheek
Low-crowned; any tooth whose width exceeds the height of the crown above the alveolus
Low crownded squarish teeth, capped with enamel, and possessing four major cusps arranged in a rectangle (as in pigs and humans)
Having teeth that are all essentially similar, usually simple cones
Paired bones in the front of the upper jaw that bear the incisor teeth
A longitudinal median bony ridge dorsal to the braincase. Often formed by a coalescence of temporal ridges

A socket in which the root of a tooth is set
Condition found in the Didelphimorphia and Peramelina in which the lower jaw is not shortened and the anterior lower incisors are not greatly elongated
Paired bones that form the posterior part of the hard palate, and wall the anterior part of the interpterygoid fossa
The suture between the paired dentaries
Small head or bony prominence on a bone
The portion of the skull anterior to the orbits
Having two sets of teeth: a milk or deciduous set and then a permanent set
A pit, depession, trough, or extensive opening
