Degree of postorbital constriction
WebThis hypothesis receives support from recent comparative morphometric analyses of orbit orientation in nonprimate mammals. Increased orbital frontation (roughly equivalent to verticality) in animals with moderate degrees of orbital convergence also causes the orbital and temporal planes to diverge, necessitating evolution of a postorbital bar (Noble et … WebDec 24, 2014 · Note many of the key H. erectus cranial traits discussed in the text, including the long and low midsagittal profile, angled occipital bone, flat frontal bone, postorbital constriction, well-developed supraorbital torus with a posttoral sulcus, occipital torus, midline keeling, maximum breadth positioned low on the vault, a heavily constructed ...

WebDec 3, 2024 · Because their faces were so broad and their brains so small, they exhibit a high degree of postorbital constriction (also known as waisting), i.e. the area between the face and braincase is narrow.

WebIn physical anthropology, post-orbital constriction is a narrowing of the cranium (skull) just behind the eye sockets (the orbits, hence the name), in primates — including primitive hominids. This constriction is very noticeable in non-human primates, slightly less so in Australopithecines, even less in Homo erectus and the most primitive Homo sapiens.
