Australopithecus ramidus, a new species of early hominid from Aramis, Ethiopia.

Between 1992 and 1994 White and his team discovered the first Ardipithecus ramidus fossils in the Middle Awash area of Ethiopia. They named their discovery Ardipithecus ramidus (‘ramid’ means ‘root’ in the Afar language of Ethiopia and refers to the closeness of this new species to the roots of humanity, while ‘Ardi’ means ‘ground’ or ‘floor’). White devised the genus name Ardipithecus to distinguish this new genus from Australopithecus. 

The first Ardipithecus ramidus fossil found was dated to 4.4 million years BP on the basis of its stratigraphic position between two volcanic strata.
