StW 573 (Little Foot) is considered to be a nearly complete case of an Australopithecus female specimen that provides plenty of information on this once obscure species that helps advance prospective on them. A skull is included. In the discovery of the cast, there was evidence of dental use where it shows to be prominent. Its resemblances can be drawn to other cases found in South Africa, such as that of A. afarensis. This is a female, 1.20-1.30 meters tall, whose lower limbs are longer than her upper limbs. Her hips are modern and capable of transmitting great forces from her legs, and her hands were very large. Their body suggests a bipedal gait and, at the same time, they had a great ability to climb trees. Morphological characteristics of StW 573’s fossil are the complete limb lengths that conclude that StW 573 stood roughly to the height of 4 feet and that they exhibited forms of bipedalism due to the length of their legs. Although, it is also prominent that StW 573 displays many features that other apes present such as a S shaped curve in their collarbone along with a ventral bar. Other fragments of the cast such as the pectoral girdle and a high ridge of StW 573’s shoulder blades suggest that they had a strong upper body to support their weight while they hang from branches and climb trees. Overall this cast indicates various examples found in what one might consider human and other primates as they exhibit concepts of walking upright, early bipedalism, and locomotion through the trees.
