The Pliocene micromammalian fauna from Kanapoi, northwestern Kenya, and its contribution to understanding the environment of Australopithecus anamensis
Includes bibliographical references (leaves 164-202).

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 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 …

Landscapes of the apes: modelling landscape use of chimpanzees and early hominins across an environmental gradient.
… (i.e. chimpanzee, Ardipithecus ramidus and Australopithecus anamensis/ afarensis) landscape use along an environmental gradient from forests to savannahs to determine their adaptability to change. Based on literature review, this thesis first quantitatively defined chimpanzee landscapes as …

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 …

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 …

The Evolution of the Glenoid Region in the Hominidae: Implications for Hominid Phylogenetics
… and Homo. The Ardipithecus and Australopithecus anamensis fossils can easily be incorporated in most existing phylogenetic scenarios by extending the age of the Hominidae to 4.5 million years. Morphological similarities suggest that A. africanus is the direct ancestor of A. …

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 …

How did the Human Brain Evolve? Tracking Cerebral Changes in the Fossil Hominin Record Using Advanced Imaging Techniques and 3D Modelling
… spanning 3.7 million years and three genera (Australopithecus, Paranthropus and Homo) to identify variation in cortical imprints across hominin taxa. Our results reveal four distinct morphotypes, reflecting key evolutionary shifts in frontal and occipital lobe organisation. A mosaic pattern of …

A background investigation into the feasibility of heavy stable isotopes (87Sr/86Sr) as source tracers of early hominids
… foraging habitats of early hominids, such as Australopithecus robustus. On the basis of isotopic data from extensive dolomite sampling, it is clear that there is a wide range of variation in strontium isotope ratios for dolomite substrata around Swartkrans. This may be as a result of …

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 …

Evolution of the Hominoid Vertebral Column
… vertebral profile. By the appearance of Australopithecus, hominins evolved a cranial placement of the diaphragmatic (one that bears a change in articular facet orientation) vertebra, which generates a functionally longer lower spine while maintaining five lumbar vertebrae. In light of …

Paranthropus paradoxes: Patterns of morphological variation in East African 'robust australopithecines'
… of fossils as Paranthropus rather than Homo or Australopithecus, their expression is far from homogenous. This has resulted in a paradox of a seemingly morphologically ‘well-defined’ species that, nevertheless, encompasses a large intraspecific variability that does not always respect this …

The evolution and diversification of Pleistocene Homo
… of diversification during the transition from Australopithecus to Homo, as well as between Homo rudolfensis and other Homo groups. Importantly, they show that specimen affiliations, the effect of selection, as well as patterns of variability vary depending on the skeletal region analysed and …

Reimagining the Inner Ear: A Morphometric Modeling Approach for Establishing Shape Change in the Evolution of the Human Otolith System

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 …
