Közel száz kövülete ismert Kenyából, és Etiópiából, amik több mint 20 egyedet képviselnek. No evidence of culture has been found yet for Australopithecus anamensis but it may have used simple tools similar to those used by modern chimpanzees, including: twigs, sticks and other plant materials that were easily shaped or modified. ramidus and Sahelanthropus.. Australopiths shared several traits with modern apes and humans, and were widespread throughout Eastern and Northern Africa by 3.5 million years ago (mya). Als sehr wahrscheinlich gilt ferner, dass Australopithecus anamensis und der jüngere Australopithecus afarensis zeitlich aufeinander folgende Schwester-Arten infolge Anagenese sind. The earliest member of the genus Australopithecus is Au. This combination of apelike cranial traits with probable bipedality is reminiscent of Ardipithecus ramidus. Australopithecus is an extinct hominid which lived approximately 4 million to 2 million years ago from the Late Pliocene Period through the Early Pleistocene Period. Journal of Vertebrate Paleontology. Additional fossil discoveries suggested that this was a new species and, in 1995, Australopithecus anamensis was proclaimed.

This specimen deomstrated the typical shallow palate and robust canine teeth with well developed roots and a pointed crown. Nature 393, 62-66. The cranium combines some more ancestral features, such as a protruding face and a long and narrow braincase, with some more derived features, such as forwardly projecting cheekbones similar to Paranthropus. The fossilised remains of this species were found trapped between different layers of ash and this has enabled this species’ fossils to be reliably dated to between 3.8 and 4.2 million years in age. The oldest known stone tools are around 3.3 million years old and were unearthed in Kenya.

Claimed as one of the most significant discoveries in the field of human evolution, the fossils possibly represent the oldest known human ancestor after the split of the human line from that of the chimpanzees. The region was subject to volcanic activity and various volcanic eruptions produced layers of volcanic ash that covered the ground. Some take the relationship further, proposing that these individuals are members of A. afarensis rather than a separate species and that the A. anamensis fossils are simply earlier representatives of a single evolving A. afarensis lineage (a chronospecies). Australopithecus is an extinct genus of hominins. Ward, C. Leakey, M., Walker, A., 1999. Researchers have since found other Au.

These wider fingertips increase the stability of small items you hold in a precision, pincer grip such as stone tools. This species may be a direct descendant of the 4.4 Ma Ardipithecus ramidus, but the relatively thick enamel seen in KNM-KP 29281, as well as the proportions of its teeth, suggest dietary and/or masticatory differences between Au. However, Australopithecus species had hands that were well suited for the controlled manipulation of objects, and they probably did use tools. Nature 573, 214-221. Australopithecus anamensis individuals had thickly-built, long, narrow jaws with their side rows of teeth arranged in parallel lines. anamensis individuals may at times have eaten hard, abrasive foods, but they likely were plant-eaters in general, relying on both fruits and tough foods such as nuts.
