Australopithecus anamensis

The Australopithecus anamenis were originally called the Australopithecus afarensis in 1994 but then changed to Australopithecus anamenis in 1995 when researches noticed many difference between these early Kenyan hominid species. Australopithecus anamenis is approximately a four-million-year-old hominid species from Kenya. The term anam means 'lake' in the Turkana language. They were named this because they were found by Lake Turkana on this site, they also discovered 8 other new hominid species. On the site Kanapoi where they discovered 12 fossil specimens of the australopithecus anamensis. The first Australopithecus anamenis discovery occurred in the Kanapoi region of East Lake Turkana in 1965 by a Harvard University expedition. The original findings consisted of a partial left humerus and a solitary molar which was discovered in 1982. It wasn't until the early 1990's that The National Museum of Kenya organized a reasearch team for the region of Kanapoi. Many of the nine species discovered were very similar, but there were small differences that helped to distinguish one species from another, some of those differences were body weight of the males, and dental samples from the females.
The features that the australopithecus anamensis would have are:
less space between the tibia and fibula then in apes
the shaft of the tibia was straight
anamensis was powerfully built, but that does not show evidence of body weight
thickened cortical bone at the proximal and distal ends
the molar enamel was not as thick as other species
