| orbit | mammal, turtle, reptile a skeletal cavity comprised of seven bones situated within the skull. The cavity surrounds and provides mechanical protection for the eye and soft tissue structures related to it |
| foramen magnum | mammal, reptile, turtle, necturus a large, oval-shaped opening in the occipital bone of the skull |
| infraorbital canal | mammal a canal found at the base of the orbit that opens on to the maxilla |
| lacrimal | mammal, alligator, bowfin a small and fragile bone of the facial skeleton. it is situated at the front part of the medial wall of the orbit. functions with creating tears |
| zygomatic process of the temporal | mammal a long, arched process projecting from the lower part of the squamous portion of the temporal bone. It articulates with the zygomatic bone |
| zygomatic bone | mammal also called cheekbone or malar bone, is a paired irregular bone which articulates with the maxilla, the temporal bone, the sphenoid bone and the frontal bone |
| zygomatic arch | mammal the cheek bone that is formed by the zygomatic processes |
| mastoid process | mammal bony projection at the base of the temporal bones behind your ears. It is an attachment point for several muscles and contains air cells that help drain fluid from the middle ear |
| styloid process | human, mammal a slender bony process of the temporal bone extending downward and forward from the undersurface of the temporal bone just below the ear. The styloid process gives attachments to several muscles, and ligaments |
| occipital condyle | mammal, turtle undersurface protuberances of the occipital bone in vertebrates, which function in articulation with the superior facets of the atlas vertebra |
| tympanic bulla | cat, mammal a curved plate of bone lying below the squamous part of the temporal bone, in front of the mastoid process, and surrounding the external part of the ear canal |
| external auditory meatus | mammal, alligator ear canall |
| palatine process of premaxilla | cat, mammal, reptile the palatine process of maxilla, is a thick, horizontal process of the maxilla. It forms the anterior three quarters of the hard palate, the horizontal plate of the palatine bone making up the rest |
| palatine | mammal, turtle paired bone in the posterior part of the hard palate and the floor of the nasal cavity |
| vomer | mammal, turtle, necturus one of the unpaired facial bones of the skull. It is located in the midsagittal line, and articulates with the sphenoid, the ethmoid, the left and right palatine bones, and the left and right maxillary bones |
| mandible | mammal the mandible, lower jaw, or jawbone is a bone that makes up the lower – and typically more mobile – component of the mouth |
| mental formina | mammal foramina located on the anterior surface of the mandible. It is part of the mandibular canal. It transmits the terminal branches of the inferior alveolar nerve and the mental vessels |
| ramus | mammal ramus of the mandible is a flat, triangular bone that is located on the posterior aspect of the mandible |
| condyloid process | mammal the process on the human and other mammalian species' mandibles that ends in a condyle, the mandibular condyle |
| coronoid process | mammal, turtle the mandible's coronoid process is a thin, triangular eminence, which is flattened from side to side and varies in shape and size |
| turbinate bone | cat, mammal a long, narrow, curled shelf of bone that protrudes into the breathing passage of the nose in humans and various animals |
| pterygoid process | cat, mammal, turtle, necturus one on either side, descend perpendicularly from the regions where the body and the greater wings of the sphenoid bone unite |
| prefrontal bone | reptile, turtle a bone separating the lacrimal and frontal bones in many tetrapod skulls |
| palatine process of maxilla | reptile the palatine process of maxilla, is a thick, horizontal process of the maxilla |
| dentary | reptile, turtle, necturus, bowfin The single bone that makes up the mammalian lower jaw is the dentary |
| articular | reptile, turtle a joint, such as the cartilage that covers the ends of bones |
| quadrate | reptile, turtle, necturus he quadrate bone connects to the quadratojugal and squamosal bones in the skull, and forms upper part of the jaw join |
| quadratojugal | reptile, turtle a thin and rodlike element of the skull. Upon ossification, the jugal and quadratojugal bones fuse to form the jugal bar, which is homologous to the lower temporal bar of other diapsids |
| jugal | reptile, turtle, bowfin connected to the quadratojugal and maxilla, and has a function of supporting the eye and biting muscles |
| postorbital bar | alligator a bony arched structure that connects the frontal bone of the skull to the zygomatic arch, which runs laterally around the eye socket |
| supratemporal fenestra | alligator openings in the temporal region of the skull of some amniotes, behind the orbit. These openings have historically been used to track the evolution and affinities of reptiles |
| infratemporal fenestra | alligator paired openings in the lower, temporal region |
| squamosal | alligator, turtle, necturus the squamosal and quadratojugal bones form the cheek series of the skul |
| external nares | turtle nose holes |
| postorbital | turtle, bowfin one of the bones in vertebrate skulls which forms a portion of the dermal skull roof and, sometimes, a ring about the orbit. Generally, it is located behind the postfrontal and posteriorly to the orbital fenestra |
| supraoccipital | turtle situated or performed over or in the upper part of the occiput |
| stapes | turtle the smallest bone in the human body and the innermost of the ossicles in the middle ear. It connects with the incus and the oval window and helps generate a sound wave in the inner ear. |
| surangular | turtle, bowfin Usually in the back of the jaw, on the upper edge, it is connected to all other jaw bones: dentary, angular, splenial and articular. It is often a muscle attachment site. |
| angular | turtle, bowfin a large bone in the lower jaw of amphibians and reptiles, which is connected to all other lower jaw bones: the dentary, the splenial, the suprangular, and the articular. It is homologous to the tympanic bone in mammals |
| supramaxilla | bowfin one of the elements forming the upper jaw of various primitive bony fishes. |
