Geographic variation in the phenotypes of two sibling horseshoe bats Rhinolophus simulator and R.swinnyi
… 2) and hard tissue parameters (Chapter 3), i.e., 3D scanned skulls analysed using 3D geometric morphometrics. To reconstruct the selective forces, linear mixed-effects models were used to regress climatic variables against echolocation call signals (Chapter 4) based on two hypotheses, the Sensory …

Human Physiology and Acheulean Handaxe Design
… size differences between three-dimensional (3D) objects by using a series of different sized 3D printed models which were presented to participants who were asked to iii differentiate the size differences. The results indicate that our ability to distinguish size differences drops …

Paranthropus paradoxes: Patterns of morphological variation in East African 'robust australopithecines'
… high-resolution imaging, landmark-based 3D geometric morphometrics, and machine learning methodologies. Comparisons of ca. 60% of all original P. boisei fossil mandibles to those of living hominoids reveal the first sex estimation of individual fossils with an associated statistical …

Quantifying variation in teeth of Late Triassic vertebrates: implications for identification, palaeoecology, and biostratigraphy
… teeth, particularly within Dinosauria, but 3D methods have been underutilised, despite the increasing availability of scanned fossils and increased information on dimensionality that can be captured by using 3D models. My dissertation quantified variation in tooth morphologies at three …

A 3D Geometric Morphometric Investigation of Relatedness in the Modern Human, Chimpanzee, and Homo naledi Postcranial Skeleton
… the H. naledi assemblage. The data consisted of 3D models of 556 postcranial elements (first metacarpal (Mc1), proximal femur, talus, calcaneus, and navicular) from 187 individuals that were generated from surface scanners or downloaded from MorphoSource.</p><p>This dissertation employed a …
