Sts 5, "Mrs Ples", Australopithecus africanus Discovered by Robert Broom in 1947 at Sterkfontein in South Africa. It has usually been thought to be female, but there has been a recent claim that it is male. It is about 2.5 million years old, with a brain size of about 485 cc.
(It has recently been claimed that the fossils Sts 5 and Sts 14 (see next entry) were from the same individual) Sts 14, Australopithecus africanus Discovered by Robert Broom and J. Robinson in 1947 at Sterkfontein (Broom and Robinson 1947). This find consisted of a nearly complete vertebral column, pelvis, some rib fragments, and part of a femur of a very small adult.
Each entry will consist of a specimen number if known (or the site name, if many fossils were found in one place), any nicknames in quotes, and a species name. ARA-VP-6/500, "Ardi", Ardipithecus ramidus Discovered by a team led by Tim White in 1994 at Aramis in Ethiopia (White et al. KP 271, "Kanapoi Hominid", Australopithecus anamensis Discovered by Bryan Patterson in 1965 at Kanapoi in Kenya (Patterson and Howells 1967).
They are however mostly fragmentary, often consisting of single bones or isolated teeth. The list is sorted by species, going from older to more recent species. A braincase is the cranium minus the face and upper jaw.

This is a mostly complete cranium with a small brain (between 320 and 380 cc). 2002, Wood 2002) It has many primitive apelike features, such as the small brainsize, along with others, such as the brow ridges and small canine teeth, which are characteristic of later hominids. Most remains are teeth, but there is also a partial lower jaw of a child, a partial cranium base, and partial arm bone from 2 individuals.Their size and stride length indicate that they were about 140 cm (4'8") and 120 cm (4'0") tall.Many scientists claim that the footprints are effectively identical to those of modern humans (Tattersall 1993; Feder and Park 1989), while others claim the big toes diverged slightly (like apes) and that the toe lengths are longer than humans but shorter than in apes (Burenhult 1993). afarensis, because no other hominid species is known from that time, although some scientists disagree with that classification. This is a 70% complete skull of a large adult male, easily the most complete afarensis skull known, with a brain size of 550 cc.Johanson believes they belong to a single species in which males were considerably larger than females.Others believe that the larger specimens belong to a primitive species of Homo. Discovered in 1978 by Paul Abell at Laetoli in Tanzania. The trail consists of the fossilized footprints of two or three bipedal hominids.
