The human face is composed of the maxillary, zygomatic (also known as the jugal), nasal, lacrimal, palatine, vomer, and turbinate bones. During fetal development, the premaxillary bones fuse to the maxillary. Do other vertebrates possess these bones in their faces? In what way are they similar or different from humans?
