Dental pathology, wear and developmental defects in South African hominins
… species studied include Paranthropus robustus, Australopithecus africanus, A. sediba, early Homo, Homo naledi, baboons, chimpanzees and gorillas. Macroscopic examination of each specimen was performed, with a 10X hand lens used to verify certain pathologies. Variables recorded include antemortem …

The Makapansgat Hominins: A Descriptive and Comparative Morphological Study
… recognized taxa of South African <italic>Australopithecus<italic>. Results support previous assertions that the Makapansgat specimens share morphological similarities with both <italic>Australopithecus africanus<italic> and <italic>Australopithecus robustus<italic> and that these taxa …

Dental Microwear Textures of Paranthropus robustus from Kromdraai, Drimolen, and an Enlarged Sample from Swartkrans: Ecological and Intraspecific Variation
… that are seen in occasional hard object feeders. Australopithecus africanus has higher anisotropy values (epLsar) consistent with consuming tough objects. This study expands upon this baseline by increasing the sample size from n = 9 for P. robustus and n = 10 for Au. africanus to n = 66 and n = …

Effects of Instrumentation on Dental Microwear Textures: Reanalysis and Augmentation of an Early Hominin Sample
… first study examines a sample of hominin molars (Australopithecus africanus and Paranthropus robustus) for comparison with data previously scanned and analyzed on the University of Arkansas' Plu Standard confocal microscope (Scott et al., 2005). The second study expands the sample of early …

Reimagining the Inner Ear: A Morphometric Modeling Approach for Establishing Shape Change in the Evolution of the Human Otolith System
… otolith system. Specimens representing <em>Australopithecus africanus</em> and <em>Paranthropus robustus</em> exhibit major morphological differences compared to <em>H. sapiens</em>, while La Chapelle aux saints 1 (representing <em>Homo neanderthalensis</em>) shares most features with <em>H. …

Reconstructing Soft Tissues of Plio-Pleistocene Hominids using Comparative Anatomy of Modern Humans & Great Apes
… ancient hominid, such as those belonging to the Australopithecus or Paranthropus genera. Facial approximations provide a 3D model for these species and provides another means for scientists to understand the morphological differences between and variations among archaic hominids and modern …

Using a multiproxy analysis of springbok fossils to track 2 million years of vegetation changes experienced by hominins in southern Africa.
… (with the appearance and disappearance of Australopithecus africanus, Australopithecus sediba, Paranthropus robustus and the emergence the Homo genus) requires greater understanding of the underlying catalysts for paleoenvironmental change and resultant pressures subjected upon the fauna …

Uranium-Lead dating of hominid fossil sites in South Africa
… StW 573 may come under the classification of Australopithecus africanus and be contemporaneous with the fossil Sts 5, also from Sterkfontein, which had previously been considered to postdate StW 573. It also confirms that the South African branch of this genus is probably not as ancient as the …

Comparative Digital Examination of the Talocrural (ankle) Joint Provides Insight into Human bipedal locomotion
… million year old Ardipithecus ramidus, 3.2 Ma Australopithecus afarensis, 1.8 Ma Homo habilis), non-human primates (N=29), ursids (n=3), and felids (n=2) were created and shapes of the talocrural joint surfaces were analyzed to identify locomotor patterns. Locomotor modality was identifiable …
