The mixed dentition and associated skull fragments of a juvenile fossil hominid from Sterkfontein, South Africa
In April-May 1983, the late A.R. Hughes and his field team recovered more than 40 bone fragments and teeth from a single solution pocket of the Sterkfontein Formation. After preparation and reconstruction by JMC, it was recognised that these fragments represent a single juvenile individual (Stw 151), consisting of more than 40 cranial and dental parts, with mixed dentition. It constitutes the most complete set of jaws and teeth of an early homini…

Variations in molar enamel thickness among primates
Because of its hardness, resistance to abrasion and its influence on crown morphology, molar enamel thickness is an important factor in adaptation of the dentition to the diet. Enamel thickness has also been discussed extensively in relation to the phylogenetic relationships among the hominoids. The aims of this study were: (1) to analyse enamel thickness/tooth size relationships among primates as a whole, and (2) to evaluate variations in enamel…
Comparative dental development and microstructure ofProconsulteeth from Rusinga Island, Kenya
Climatic effects on dental development ofTheropithecus oswaldi from Koobi Fora and Olorgesailie
Histological reconstruction of dental development and age at death of a juvenile Paranthropus robustus specimen, SK 63, from Swartkrans, South Africa
There has been disagreement about whether the earliest hominids grew in a similar manner to great apes or modern humans. This has important biological implications, since it may have been inappropriate to apply modern human developmental standards to early hominids. The aim of the present study was to combine data from replicas of tooth surfaces, computed tomographic (CT) scans, and radiographs with data from a histological section of the canine …
A longitudinal study of tooth growth in a single individual based on long- and short-period incremental markings in dentine and enamel
Ground sections of teeth from a single individual revealed approximately 30 fluorescent lines in the dentine resulting from successive courses of tetracycline antibiotics given over a period of approximately 12 years. In addition, many teeth showed long-period incremental markings in the dentine. Short-period daily cross-striations in the enamel were used to calculate the periodicity of the long-period incremental lines in both enamel and dentine…
Tooth crown heights, tooth wear, sexual dimorphism and jaw growth in hominoids
The aim of this review is to bring together data that link tooth morphology with tooth function and tooth growth: We aim to show how the microanatomy of hominoid teeth is providing evidence about rates of tooth growth that are likely to be a consequence of both masticatory strategy and social behaviour. First, we present data about incisor and molar tooth wear in wild short chimpanzees that demonstrate how crown heights are likely to be related t…
On thick and thin enamel in hominoids
Martin (1983, 1985) reviewed the significance of enamel thickness in hominoid evolution. He studied cut faces of hominoid teeth using the scanning electron microscope and related enamel prism packing patterns to both enamel formation rates and enamel thickness, although he did not present primary data on formation rates, which he summarised as being either “fast” or “slow.” Martin concluded that thick enamel formed at a fast rate represented the …
Histological reconstruction of crown formation times and initial root formation times in a modern human child
Previous qualitative studies on root growth in hominoids have suggested that the early stages of root growth in modern human teeth are slower than in great apes, but no quantitative data on root extension rates exist for modern human teeth. The primary objective of this study was to use incremental markings in the crowns of teeth to provide information about crown formation times and early root formation times. This study provides a detailed desc…
Histological study on the chronology of the developing dentition in gorilla and orangutan
The single previous study on tooth development in great apes (Dean and Wood: Folia Primatol . ( Basel ) 36 :111–127, 1981) is of limited value because it is based on cross‐sectional radiographic data. This study considers problems in defining stages of tooth development in radiographs of developing ape dentitions and provides data on tooth chronology in Pongo pygmaeus and Gorilla gorilla by using histological methods of analysis. Crown formation …
Distinct dental development patterns in early fossil hominids
Patterns and rates of enamel growth in the molar teeth of early hominids
Variations in enamel thickness and structure in East African hominids
Tooth fragments are an appreciable but neglected proportion of fossil hominidspecimens. The present study on 47 naturally fractured enamel surfaces of premolar and molar teeth of Plio‐Pleistocene East African hominids measured enamel thickness, slope of incremental lines (striae of Retzius), and the morphology of Hunter Schreger bands (HSBs). Specimens allocated to three categories—“robust” australopithecines (EAFROB), “early Homo ” (EAFHOM), and…
