Unlocking the Secrets of Fossulae in Extinct Species

Fossulae (singular: fossula) are small, irregularly-shaped holes or depressions in the bone that are often found in the skulls of extinct species of humans and other primates. They are thought to have been caused by the presence of blood vessels or nerves, which left behind small channels or cavities in the bone as they grew and developed.

Fossulae can be useful for paleoanthropologists because they can provide information about the growth and development of extinct species, as well as the evolution of their skulls and brains over time. For example, the size and shape of fossulae can indicate the age at which an individual died, or the sex of the individual (in some cases, males and females have different patterns of fossulae). Additionally, the presence or absence of certain types of fossulae can be used to distinguish between different species or subspecies of extinct humans and primates.
