  Australopithecines
Some believe that some of the australopithecine species are directly ancestral to humans, however others hold they are a "side-branch" of the line that led to humans, and not direct human ancestors.
africanus, which are termed "gracile." The smaller gracile forms Australopithecus africanus and Australopithecus afarensis (the species which includes the famous fossil “Lucy") are typically thought to be the most closely related to humans.
Studies have found that Australopithecus africanus (very similar to Australopithecus afarensis), the australopithecine species often thought to be the most closely related to humans, had a body shape more similar to modern apes than to members of the genus Homo.

The large-toothed australopithecines also had skeletons indicative of a heavier build than the small-toothed australopithecines; the former are believed to have weighed 25 to 50 lb (10 to 20 kg) more than the latter, even though they were approximately the same height.

 Australopithecus africanus
The species of Australopithecus africanus was named in a February, 1925, issue of Nature by Raymond Dart.
africanus was bipedal due to the position of the foramen magnum, and was vindicated by later finds, such as STS 14, which showed unequivocally that africanus was an obligate biped.
Walker and M. Wolpoff claim that the africanus chewing pattern is similar to modern hunter-gatherer groups, with the molars and premolars designed to last a lifetime of wear and tear (the oldest individuals dying at about the time they have no crowns left in their mouth - max age about 35).

Frontal view of a cast of a skull of Australopithecus africanus from Taung, Cape Province, South Africa.

As far as I can gather, Australopithecus africanus, which was first found in the Taung Caves in South Africa (and is called the "Taung child"), has not been found in Kenya.
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.

 Australopithecus africanus Skull (Taung Child) Bone Clones BH-016
Australopithecus africanus Skull (Taung Child)was the first early hominid found in Africa, discovered in Taung, Bechuanland.
Anatomy professor Raymond Dart identified this infant skull as a new, intermediary genus and species of hominid in 1924 (Australopithecus africanus means "man-ape of Southern Africa").
The skull, though immature, features hominid rather than apelike characteristics: a rounded, high forehead lacking browridges, rounded dental arcade, no space between canine and first lower premolar, relatively large fossilized brain and a foramen magnum (the hole under the skull from which the spinal cord emerges) positioned forwardly under the skull indicating bipedal locomotion.

 Australopithecus - Wikipedia, the free encyclopedia
Until recently, the footprints have generally been classified as Australopithecine because that had been the only form of pre-human known to have existed in that region at that time; however, some scholars have considered reassigning them to a yet unidentified very early species of the genus Homo.
The fossil record seems to indicate that Australopithecus is the common ancestor of the distinct group of hominines, now called Paranthropus (the "robust australopithecines"), and most likely the genus Homo which includes modern humans.

In the Nature paper published by Dart, he stated that the Taung individual was an earlier form of human, and named it Australopithecus africanus ("southern ape from Africa").
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.
A bipedal posture was again indicated by the central position of the foramen magnum, and by the anatomy of the spine, pelvis, and femur.

The first discovery of an early hominid species in Africa was by Raymond Dart, pictured at left, who found this well preserved skull of a juvenile in South Africa in 1924.
Dart named this newly discovered species Australopthicus africanus, or "Southern Ape of Africa." This speciman of a child, often called the "Taung Baby," after the site in which it was discovered, preserves remarkable physical details.
An imprint of the brain case is preserved in limestone, and the foramen magnum, the opening in the skull through which the spinal cord attaches to the brain, indicates that this creature walked upright like human beings.
