Supraorbital ridge

Supraorbital ridges are significant thickenings of the lower part of the scales of the frontal bones, which are characteristic of some higher primates. They can also be found in some of the oldest fossil human ancestors, such as Archanthropus.

The supraorbital ridge is an important anatomical feature that can be used to determine whether an animal belongs to a particular species or genus. It can be used to identify ancient human and animal remains, and to study the evolution and phylogeny of various primate species.

Additionally, the supraorbital ridge may be associated with certain behavioral traits such as aggressiveness, territoriality, or social hierarchy. This could help scientists better understand the behavior of ancient primates and humans.

Overall, the study of supraorbital ridges is an important area of ​​anthropology and paleontology that helps us better understand the evolution and development of primates and humans.

Supraorbital ridges are characteristic of different species of placental primates and indicate some similarity in their facial structures and functioning. These elements of the skull bone are observed in Homer's gorilla, chimpanzees, bonobos, orangutans, as well as in extinct species - gelada, archaic man. The key feature of primate bones is the compactness and density of the skull structure, the absence of neoplasms in the form of osteophytes, sutures and holes in the bones that can pass blood and connective tissue to the internal structures of the head, as in non-primates.

The supraorbital ridge may appear as a flat ridge
