Sorting of Proximal and Distal Long Bone Fragments Using Diaphyseal Cross‐Sectional Geometric Properties
The re‐association of skeletal remains has been one of the core challenges for anthropological studies of commingled skeletal elements. However, there has been a lack of methodologies focusing on the re‐association of fragmented remains. This work proposes a novel method for the screening of fragmented long bone diaphysis, based on the geometric properties of their 20% and 80% diaphyseal cross‐sections and utilizing support vector machine models.…
Stature estimation equations from fragmentary long bones based on a modern Eastern Mediterranean assemblage
Stature estimation is central in forensic anthropology and very important in bioarchaeology. For this reason, several different methods have been proposed, employing different skeletal elements and statistical approaches. A major issue with skeletonized individuals is that their bones are often found fragmented, a taphonomic parameter that limits the application of many available methods. As a result, attempts have been made to create equations t…
Testing the accuracy of the SexEst software for sex estimation in a modern Greek sample
Sex estimation from human skeletal remains is fundamental in osteoarcheology and forensic anthropology. The increasing availability of reference skeletal collections across the world has allowed the development of morphological and metric methods for skeletal sex estimation, some of which may be implemented in specialized computer software. The present study aims to evaluate the freely available SexEst software, which utilizes cranial and postcra…
Evaluating cross-sectional geometry-based methodologies on an archaeological and historical sample
The construction of a complete biological profile for unknown individuals from skeletal remains plays a key role in the holistic study of archaeological sites. However, the presence of commingled elements, as in the case of mass graves, hinders this process. This work aims to evaluate the diaphyseal cross-sectional geometric properties of the long bones for pair-matching and for sex estimation based on the femur, tibia, and humerus bones on archa…
Integration patterns of the asymmetric components of the skull
The asymmetric variation of the skull regions should be taken into consideration for surgical treatment planning. However, comparing our findings with other studies revealed that the utilization of the skull regions in the context of a structure as a whole while running the analysis, as well as different landmark combinations, may lead to different results. Furthermore, there might be population-specificity to certain integration patterns of the …
The impact of activity on pelvic age-at-death estimation
This study assesses whether greater levels of physical activity result in increased rates of degenerative change in the pubic symphysis and the iliac auricular surface. The sample comprises 131 skeletons from the Athens Collection. Skeletal age-at-death was estimated from the pubic symphysis and the iliac auricular surface. Skeletal activity was assessed using femoral cross-sectional geometric (CSG) properties and fibrocartilaginous entheses. The…
"What and how should we share?" An inter-method inter-observer comparison of measurement error with landmark-based craniometric datasets
The present study evaluates the precision and accuracy of photogrammetric 3D modeling of human crania in landmark acquisition and explores the limitations of combining datasets acquired by different observers and different measurement methods. Our working sample comprises 50 adult human crania, which were modeled with 3D photogrammetry. 3D coordinates of 56 landmarks were collected from the 3D models with Meshlab software and an existing correspo…
A three‐dimensional digital microscopic investigation of entheseal changes as skeletal activity markers
OBJECTIVES: The current article explores the effectiveness of entheseal changes (EC) as skeletal activity markers by testing the correlation between such changes and cross-sectional geometric (CSG) properties while controlling for the effect of age and body size. MATERIALS AND METHODS: The originality of the article lies in capturing EC in a continuous quantitative manner using three-dimensional microscopy. Roughness and bone resorption were reco…
Validation study of osteometric techniques for sorting commingled human skeletal remains in archaeological samples
The biological profile of human remains is fundamental for understanding the structure of past societies and their life histories. However, the assessment of the demographics of an assemblage is hindered when dealing with commingled burials. Consequently, methods for sorting commingled skeletons are essential in a bioarchaeological context. The aim of this study was to provide insight into osteometric sorting techniques when dealing with archaeol…
Secular change in adult stature of modern G reeks
OBJECTIVES: In Greece, during the late 19th and early 20th century, the rural population adopted a more or less urban lifestyle. Furthermore, the first half of the 20th century finds Greece involved in five major wars, including a civil war, and consequent financial deprivation. This study investigates how the socioeconomic changes in Greece, during this period of time, have affected the stature of its population. METHODS: The Athens collection c…
Regression equations for the estimation of stature and body mass using a Greek documented skeletal collection
Estimating Sex of Modern Greeks Based on the Foramen Magnum Region
Sex determination is one of the principal aims when examining human skeletal remains. One method for sex determination is based on metric criteria using discriminant functions. However, discriminant function sexing formulas are population-specific. In the present study, we determined the use of the foramen magnum as well as the occipital condyles for sex determination on adults from a modern Greek population. Seven parameters were examined (4 obt…
Sex determination by three-dimensional geometric morphometrics of the vault and midsagittal curve of the neurocranium in a modern Greek population sample
An attempt to predict tooth crown height using cementoenamel junction diameters and implications in the quantitative study of dental wear
Dental wear has been used extensively in osteoarchaeological studies as a means of exploring dietary patterns and the use of teeth as tools. The present paper aims to test whether crown height can be predicted for premolars and molars based on the mesiodistal and buccolingual diameters of these teeth at the level of the cementoenamel junction (CEJ). Multiple linear regression was used with crown height as dependent variable and diameters at the C…
Sex determination by three-dimensional geometric morphometrics of craniofacial form
The purpose of the present study is to define which regions of the cranium, the upper-face, the orbits and the nasal are the most sexually dimorphic, by using three-dimensional geometric morphometric methods, and investigate the effectiveness of this method in determining sex from the shape of these regions. The study sample consisted of 176 crania of known sex (94 males, 82 females) belonging to individuals who lived in Greece during the 20(th) …
Sex determination by three-dimensional geometric morphometrics of the palate and cranial base
The purpose of this study is to assess sexual dimorphism in the palate and base of adult crania using three-dimensional geometric morphometric methods. The study sample consisted of 176 crania of known sex (94 males, 82 females) belonging to individuals who lived during the 20th century in Greece. The three-dimensional co-ordinates of 30 ectocranial landmarks were digitized using a MicroScribe 3DX contact digitizer. Generalized Procrustes Analysi…
