  Australopithecus - Wikipedia, the free encyclopedia
The gracile australopithecines (members of the genus Australopithecus) are a group of extinct hominids that are closely related to humans.
The brains of most species of Australopithecus were roughly 35 percent of the size of that of a modern human brain.
The fossil record seems to indicate that Australopithecus is the common ancestor of the distinct group of hominins, now called Paranthropus (the "robust australopithecines"), but are not ancestral to the genus Homo, which includes modern humans.

 Australopithecus garhi - Wikipedia, the free encyclopedia
Australopithecus garhi is a gracile australopithecine species whose fossils were recently discovered.
The remains were initially believed to be a human ancestor species and the final missing link between the Australopithecus genus and Homo (Man).
The partial cranium shares a mixture of traits of those seen in Australopithecus afarensis and Australopithecus africanus, such as the shape and size of its dentition.

 Hominid Chronology
Australopithecus afarensis continued to roam a mixed habitat of savannah and woodland beside lakes and floodplains, foraging for fruit, seeds and nuts and maybe even some meat.
As Australopithecus afarensis and bahrelghazali disappeared, the first hominid to replace them was Australopithecus africanus, a direct descendant of afarensis, which lasted until 2.4 million years ago.
It was a short-lived side-shoot of Australopithecus africanus, and existed alongside it.

Australopithecus afarensis had a brain size hardly larger than those of chimpanzees (about 350 to 500 cu cm [21.6 to 30.5 cu in]).
As with Australopithecus afarensis, no stone tools have been found in association with Australopithecus africanus fossils, and, as in the earlier species, hip and limb bones suggest that while these creatures were regular bipeds, they still had ape-like body proportions and other characteristics.
