  Australopithecus garhi   (Site not responding. Last check: 2007-11-06)
Australopithecus anamensis, 3.9 to 4.1 ma, from Kanapoi and Allia Bay, Lake Turkana district, northwestern Kenya.
Australopithecus africanus, the earliest described species, from South Africa; it has long known from the sites of Taung, Sterkfontein and Makapansgat, and recently specimens have begun to be excavated at other sites in the Sterkfontein Valley (Drimolen and Gladysvale).
The type specimen of Australopithecus garhi is a partial cranium; from nearby sites, and perhaps belonging to the same species or perhaps not, come several postcranial bones including a partial skeletons, a fragment of a second cranium, and two mandibles (one fairly complete).

Australopithecus is an important ancient genus of humanlike creatures, or hominids.
Australopithecus anamensis had a significantly thicker layer of enamel on its teeth than Ardipithecus, suggesting the later hominid was adapting to eating a more abrasive diet of roots.
Australopithecus afarensis was first recognised in the 1970s on the basis of the now famous "Lucy" skeleton from Hadar, Ethiopia, and footprints preserved in volcanic ash at Laetoli, Tanzania.

Australopithecus were actually on the ark, but since then they have sinned by eating too many shrimp and were punished by extinction.
Actually, there's evidence for a changing climate bringing grasslands to east Africa, and some have speculated that this may have been the ax that cleaved Homo from his fellow primates: Man adapted to walking upright on the open savanah (and was joined by baboons), while the chimps and others remained in the forest.
I was speculating that Australopithecus might have existed while that process was going on, and they were adapted to walking between stands of trees but still found value in climbing up them when possible to avoid predation.

 Hominid fossils from Ethiopia link ape-men to more distant human ancestors
The hominid Australopithecus has often been called an ape-man because, though short-statured, small-brained and big-toothed, it walked on two legs unlike the great apes.
Since the first Australopithecus skull, the famous Taung child, was discovered in South Africa 82 years ago by Raymond Dart, fossils of this hominid have been found all over eastern Africa spanning a 3-million-year time period.
"Australopithecus became a superior omnivore, able to eat tubers and roots with more fiber and grit, adapting it better to times of scarcity during periods of extended drought," he said.

 ABC - Walking with Beasts - Australopithecus Detailed Evidence
Australopithecus, whilst walking upright, lived on the edges of the savannah and spent quite a lot of its time in the trees.
Because Australopithecus walked upright, their pelvis was more similar to humans and it seems more likely that Australopithecus females' genitalia were also adapted for mating face to face.
Australopithecus males seem to have been much larger than the females, and they have larger canine teeth (although the canine teeth are much smaller than in some other primates), and this implies that they were living in groups, like their close cousins the modern apes and humans.

 The Genus Australopithecus
The cranial capacity of the Australopithecus anamensis is unknown.
Many scientists believe Australopithecus afarensis was still active in trees because the fingers and toe bones of the species were curved and longer than the ones of the modern human.
Australopithecus africanus appeared to be apelike in having a protruding face and small brain, but had distinctly unapelike dentition, including small canines and large, flat molars.

The find vindicated Louis and Mary Leakey's work at Olduvai (which had been relatively fruitless over the previous 30 years), which led to renewed research interest in the area, added an important stage in a relatively sparse hominid lineage at the time, and also was important in focusing attention on multidisciplinary research.
Australopithecus boisei is an important species both in the history of paleoanthropological research and in constructing the phylogeny of the hominid lines.

 Australopithecus boisei - Leakey ancestors
Australopithecus boisei is one of three species included in the 'robust australopithecines' a group of early hominids distinguished by their enormous cheek teeth and very reduced incisors and canines.
Notice that the word endings of the superfamily is always "oidea", of the family is "idae" and of the subfamily is "inae".
Australopithecus boisei remains are often found with animals that live in relatively well vegetated wet habitats.

 Washingtonpost.com: Full Australopithecus Fossil Found in South Africa
There had never been more than partial fossil evidence from any individual specimen of Australopithecus ("southern ape"), the bipedal hominid believed to be the immediate evolutionary predecessor of early Homo, the first humans.
As a result, fundamental questions about Australopithecus have remained unanswered, including the size of the brain in relation to the size of the body, its likely diet, its mode of locomotion and anatomical particulars.
Two of the most familiar species are Australopithecus afarensis (of which the Ethiopian specimen named "Lucy" is the prime example) and A.

 Turkana prehistory - Traditional Music & Cultures of Kenya
Forgetting that rather simplistic image for a moment, the upshot of all this is that relatively intelligent, upright, tool-using ancestors of modern man lived in eastern Africa as early as 2.5 million or 3.6 million years ago, or almost twice the time span of previous estimates.
Australopithecus anamensis (anam is the Turkana word for lake) is thus the earliest bipedal hominid yet found, and the discovery has only started to fuel more controversy about whether australopithecus could indeed have been our direct ancestor.
The first remains of Australopithecus anamensis, incidentally, were discovered at Kanapoi in 1965, but were not properly classified as such until the 1990s discoveries.

Nine hominid dental, cranial and postcranial specimens from Kanapoi, Kenya, and 12 specimens from Allia Bay, Kenya, were described as a new species of Australopithecus in the August 17, 1995 issue of Nature.
The relationship between Australopithecus afarensis and Ardipithecus ramidis, a potential ancestral species for all Hominidae, can now be assessed with more temporally intermediate evidence.
Australopithecus anamensis fossils were initially discovered in 1965, when the distal end of a humerus (KNM-KP 271) was recovered at Kanapoi.

Australopithecus afarensis and africanus, and the other species above, are known as gracile australopithecines, because of their relatively lighter build, especially in the skull and teeth.
Australopithecus aethiopicus, robustus and boisei are known as robust australopithecines, because their skulls in particular are more heavily built.

 Australopithecus afarensis (Lucy)
Lucy's dentition is a cross between ape and human in that the overall shape is apelike while the canine tooth size resembles that of modern humans.
The jaw also shows prognathism, a jutting forward of the lower facial features commonly found in the apes and other pre-human fossils although Lucy's jaw is not as pronounced as that of the ape.
Australopithecus afarensis led to 2 further divergences, the robust australopithecines that died out, and the gracile line leading eventually to us (Johanson, White 1979) figures a & b.

 Australopithecus aethiopicus   (Site not responding. Last check: 2007-11-06)
In 1985, a cranium was found by Alan Walker at the west side of Lake Turkana in Northern Tanzania and was named Australopithecus aethiopicus.
This cranium, known locally as the "fl skull", was surprising not only because of its great age but also because it contained an unexpected combination of anatomical characteristics.
Although the face was distinctly like that of that most robust of robust australopithecines, Australopithecus boisei, the cranium — particularly the top and back — was not: it was similar to that of Australopithecus afarensis.
