Post-orbital constrictionIn physical anthropology, post-orbital constriction is the narrowing of the cranium (skull) just behind the eye sockets (the orbits, hence the name) found in most non-human primates and early hominins. This constriction is very noticeable in non-human primates, slightly less so in Australopithecines, even less in Homo erectus and completely disappears in modern Homo sapiens. Post-orbital constriction index in non-human primates and hominin range in category from increased constriction, intermediate, reduced constriction and disappearance.
Turkana BoyTurkana Boy, also called Nariokotome Boy, is the name given to fossil KNM-WT 15000, a nearly complete skeleton of a Homo ergaster youth who lived 1.5 to 1.6 million years ago. This specimen is the most complete early hominin skeleton ever found. It was discovered in 1984 by Kamoya Kimeu on the bank of the Nariokotome River near Lake Turkana in Kenya. Estimates of the individual's age at death range from 7 to 11 years old. Although the specimen is largely considered male due to the shape of the pelvis, the sex is ultimately indeterminate due to its prepubescent age.
TrinilTrinil is a palaeoanthropological site on the banks of the Bengawan Solo River in Ngawi Regency, East Java Province, Indonesia. It was at this site in 1891 that the Dutch anatomist Eugène Dubois discovered the first early hominin remains to be found outside of Europe: the famous "Java Man" (Homo erectus erectus) specimen.
Levallois techniqueThe Levallois technique (lə.va.lwa) is a name given by archaeologists to a distinctive type of stone knapping developed around 250,000 to 300,000 years ago during the Middle Palaeolithic period. It is part of the Mousterian stone tool industry, and was used by the Neanderthals in Europe and by modern humans in other regions such as the Levant. It is named after 19th-century finds of flint tools in the Levallois-Perret suburb of Paris, France.
