In order to reconstruct environments associated with Plio-Pleistocene hominins in southern Africa, researchers frequently rely upon the animals associated with the hominins, in particular, animals in the Family Bovidae. Bovids in southern Africa are typically identified by their teeth. However, identifying the taxon of a bovid tooth is challenging due to various biasing factors. Furthermore, inaccurate identification of fossil bovids can have significant consequences on the reconstructed… Expand

An analysis of the effect of tooth wear on bovid identification
Previous research provides a method for reducing the subjectivity in taxonomic identification of species in the family Bovidae by quantifying the occlusal surface of molar teeth using ellipticalExpand
An analysis on the effect of wear on bovid tooth identification
Worn teeth can be taxonomically identified by performing elliptical Fourier analysis on the occlusal surface of their teeth, and the methodology is a valuable supplement to other methods forTaxonomically identifying bovid teeth. Expand


Quantitative morphological analysis of bovid teeth and implications for paleoenvironmental reconstruction of Plovers Lake, Gauteng Province, South Africa
This study tests a method for accurately identifying bovid teeth using Elliptical Fourier Function Analysis, suggesting that occlusal surface form can reliably differentiate between closely related, morphologically similar bovids. Expand
A comparison of machine learning techniques for taxonomic classification of teeth from the Family Bovidae
This study explores the performance of machine learning algorithms on the classification of fossil teeth in the Family Bovidae by exploring how different machine learning approaches classify the teeth and testing which technique is best for classification. Expand
3D morphometric analysis of fossil canid skulls contradicts the suggested domestication of dogs during the late Paleolithic
Morphologically, these early fossil canids resemble wolves, and thus no longer support the establishment of dog domestication in the Paleolithic, and are definitively wolves and not dogs. Expand
A field comes of age: geometric morphometrics in the 21 st century
This review describes the Procrustes paradigm and the current methodological toolkit of geometric morphometrics, and highlights some of the theoretical advances that have occurred over the past ten years since the prior review (Adams et al., 2004). Expand
Reconstructing the habitat mosaic associated with Australopithecus robustus: Evidence from quantitative morphological analysis of bovid teeth
A 2dimensionsal morphometric tool was developed for accurately identifying the abundant bovid teeth that are found in direct association with the hominins using Elliptical Fourier Function Analysis, allowing for finer resolution when segmenting the various components of the reconstructed habitat mosaics.

A review of paleontological finite element models and their validity
The true power of paleontological FEA lies in the ability to manipulate virtual representations of morphology, to make relative comparisons between models, and to quantitatively assess how evolutionary changes of shape result in functional adaptations. Expand
Acquisition of high resolution three-dimensional models using free, open-source, photogrammetric software
This guide is a guide for producing high resolution 3D models from photographs, using freely available open-source software, and demonstrates that production of digital models from specimens for research or archival purposes is available to anyone. Expand
Responses of African bovids to Pliocene climatic change
The results indicate that bovids experienced an increase in species richness and a rapid episode of change in taxonomic abundances at 2.8 ± 0.1 Ma, and that this shift was followed by gradual and prolonged changes in abundance between 2.7 and 2.4 Ma. Expand
Combining Geometric Morphometrics and Finite Element Analysis with Evolutionary Modeling: Towards a Synthesis
ABSTRACT Geometric morphometrics (GM) and finite element analysis (FEA) are increasingly common techniques for the study of form and function. We show how principles of quantitative evolution inExpand
Faunal assemblage composition and paleoenvironment of Plovers Lake, a Middle Stone Age locality in Gauteng Province, South Africa.
The paleoenvironment of Plovers Lake is reconstructed as predominantly grassland, though it was colder, moister, and more wooded than at present, pointing to greater environmental heterogeneity than has previously been documented for the region in the later Pleistocene. Expand
