Tertiary Dentine Frequencies in Extant Great Apes and Fossil Hominins

open access: yesOpen Quaternary, 2019
Tertiary dentine forms when an odontoblast is directly affected by stimuli, commonly through occlusal wear and caries. In this study the presence of tertiary dentine was recorded in three South African fossil hominin species ('Australopithecus africanus,

Ambient occlusion and PCV (portion de ciel visible): A new dental topographic metric and proxy of morphological wear resistance.

open access: yesPLoS ONE, 2019
Recently, ambient occlusion, quantified through portion de ciel visible (PCV) was introduced as a method for quantifying dental morphological wear resistance and reconstructing diet in mammals.

One or two species? A morphometric comparison between robust australopithecines from Kromdraai and Swartkrans

open access: yesSouth African Journal of Science, 2010
The type specimen of Paranthropus robustus (TM 1517, including a partial cranium) was discovered at Kromdraai near Sterkfontein in 1938 and described by Robert Broom as a new species.

Hominin palaeoecology in Late Pliocene Malawi : first insights from isotopes (13C, 18O) in mammal teeth [PDF]

open access: yes, 2011
Carbon-13 and oxygen-18 abundances were measured in large mammal skeletal remains (tooth enamel, dentine and bone) from the Chiwondo Beds in Malawi, which were dated by biostratigraphic correlation to ca. 2.5 million years ago.

‘Do larger molars and robust jaws in early hominins represent dietary adaptation?’ A New Study in Tooth Wear [PDF]

open access: yes, 2013
Diet imposes significant constraints on the biology and behaviour of animals. The fossil record suggests that key changes in diet have taken place throughout the course of human evolution.

Statistical shape modelling as a novel reconstruction tool in palaeoanthropology: A case study on fossil pelves

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 11, Page 2569-2584, November 2025.
Abstract Reconstructing incomplete anatomical regions of extinct taxa is critical for understanding their ecological and evolutionary context, including their migration patterns, reproductive strategies and environmental adaptations. In hominins, the pelvis can be particularly challenging to reconstruct because crushing and fragmentation during ...

Strontium isotopic aspects of Paranthropus robustus teeth; implications for habitat, residence, and growth

open access: yes, 2018
The strontium isotopic ratio Sr-87/Sr-86 has been studied in the Sterkfontein Valley of South Africa to infer both habitat usage and residence for a number of early hominins.

Chimpanzee subspecies and 'robust' australopithecine holotypes, in the context of comments by Darwin

open access: yesSouth African Journal of Science, 2009
On the basis of comparative anatomy (including chimpanzees, gorillas and other primates), Darwin1 suggested that Africa was the continent from which 'progenitors' of humankind evolved. Hominin fossils from this continent proved him correct.

Detecting the presence of different Retzius periodicities at the population level from repetitive linear enamel hypoplasia among Lufengpithecus lufengensis and Pongo pygmaeus

open access: yesAmerican Journal of Biological Anthropology, Volume 185, Issue 4, December 2024.
Abstract Objectives Reconstruction of life histories for fossil and living primates draws on rate of enamel layering, termed Retzius periodicity (RP in days) expressed as surface perikymata, during dental crown formation. Disclosure of RP through thin sectioning is destructive; consequently, sample sizes are inadequate to detect the range of RPs ...

Contemporaneity of Australopithecus, Paranthropus, and early Homo erectus in South Africa

open access: yes, 2020
Understanding the extinction of Australopithecus and origins of Paranthropus and Homo in South Africa has been hampered by the perceived complex geological context of hominin fossils, poor chronological resolution, and a lack of well-preserved early Homo
