Paranthropus paradoxes: Patterns of morphological variation in East African 'robust australopithecines'
The genus Paranthropus represents an iconic taxon in the hominin fossil record. Its early discovery, together with its morphological distinctiveness, have defined this genus as a unique hominin lineage parallel to our own. Paranthropus boisei, who lived in East Africa between 2.3 and 1.4 million …

Variation and the evolutionary drivers of diversity in the genus Paranthropus
Craniodental robusticity in Paranthropus has led many researchers to posit that all the species in this genus share a common adaptation to a diet of hard foods. Recent research on craniodental morphology, microwear, biomechanics, and isotopes, by contrast, has suggested that substantial variation …

Dental Microwear Textures of Paranthropus robustus from Kromdraai, Drimolen, and an Enlarged Sample from Swartkrans: Ecological and Intraspecific Variation
… done by Scott et al. (2005) and concluded that Paranthropus robustus exhibited higher complexity values (Asfc) 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 …

Cross-sectional Morphology and Mechanical Loading in Plio-Pleistocene Hominins: Implications for Locomotion and Taxonomy
… patterns in the proximal and midshaft femur of Paranthropus, fossil Homo sp. and H. erectus. Modern human and Pan models are used for comparative purposes. Cross-sectional properties in the proximal and midshaft femur of fossil hominins are examined to test the hypothesis that members of the …

How did the Human Brain Evolve? Tracking Cerebral Changes in the Fossil Hominin Record Using Advanced Imaging Techniques and 3D Modelling
… 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 brain evolution …

Dental pathology, wear and developmental defects in South African hominins
… extant primates. The 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 …

Effects of Instrumentation on Dental Microwear Textures: Reanalysis and Augmentation of an Early Hominin Sample
… 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 hominins to determine whether an …

New research methods for the analysis of fossil Anura ilia and their utility for reconstructing the palaeoenvironment of Swartkrans Cave
… belonging to the early Pleistocene hominin Paranthropus robustus, as well as a handful of early Homo fossils. In this study, the fossil Anura community of Swartkrans Cave is reconstructed in order to determine whether local environmental conditions were consistent with the idea of a refugium …

Reimagining the Inner Ear: A Morphometric Modeling Approach for Establishing Shape Change in the Evolution of the Human Otolith System
… <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. sapiens</em>. These morphological …

Reconstructing Soft Tissues of Plio-Pleistocene Hominids using Comparative Anatomy of Modern Humans & Great Apes
… 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 humans. These models, …
