Article
Full-text available
Numerous intrinsic and extrinsic factors influence bone remodelling rates and have shown to affect the accuracy of histological aging methods. The present study investigates the rib cortex from two Mediterranean skeletal collections exploring the development of population-specific standards for histomorphometric age-at-death estimation. Eighty-eigh...
Article
Full-text available
Sex estimation from skeletal remains is crucial for the estimation of the biological profile of an individual. Although the most commonly used bones for means of sex estimation are the pelvis and the skull, research has shown that acceptable accuracy rates might be achieved by using other skeletal elements such as vertebrae. This study aims to cont...
Article
Full-text available
Sex estimation is considered one of the first steps in the forensic identification process. Morphological and morphometrical differences between males and females have been used as means for morphoscopic and metric methods on both cranial and postcranial skeletal elements. When dry skeletal elements are not available, virtual data can be used as a...
Article
Fragmented human remains present a challenge for forensic experts as they attempt to identify individuals using standard forensic methods. Several histological age estimation techniques have been developed during the last fifty years to aid in this process. However, very few validation studies have been conducted in order to test their accuracy and...

This project is an innovative mixture of medical imaging and forensics with holography, animation, art and virtual reality. This alliance of art and science explores, presents and communicates the history of violence and the violence of history to diverse audiences. Anatomical detail provides the substrate for forensic analysis and interpretation w...
Article
Forensic assessment of skeletal material includes age estimation of unknown individuals. When dealing with extremely fragmented human remains that lack macro-features used in age estimation, histological assessment of the skeletal elements can be employed. Historically, microscopic methods for age assessment used by forensic anthropologists have be...

Objectives: This study evaluated chronological changes in physiological stress and levels of habitual loading of Ibizan populations from the Late Roman-Early Byzantine (LREB) to the Islamic period (300-1,235 AD) using measures of body size and bone cross-sectional properties to compare Urban LREB, Urban Medieval Islamic, and Rural Medieval Islamic...
Chapter
The aim of this paper is to provide a methodological guide on how to select, test, and use statistical procedures for sex estimation using morphological traits of the cranium expressed on an ordinal scale. R functions were developed to implement binary logistic regression (BLR) and linear discriminant analysis (LDA), and step-by-step instructions w...
Chapter
Forensic anthropologists are requested to give authorities estimates on the biological characteristics of unidentified decomposed remains in an effort to create a physical description that can be compared with a missing person’s profile, eventually leading to positive identification. To answer these questions, scientists traditionally follow a vari...

Biological evidence for the identification of a possible suspect plays a vital role in forensic investigations. Fingerprints left as impressions at a crime scene are considered valuable pieces of information due to the unique characteristics of the epidermal ridges. Over the last two decades, the relationship between ridge density and sex has been...

Footprints recovered at the crime scene are often used in a forensic investigation for positive identification of the suspects. Forensic podiatry studies have shown that biological sex can be identified through footprint analysis, however, most studies have focused on the analysis of sexual dimorphic features from footprints from a single ethnicity...
Article
Ancestry estimation from skeletal remains is a challenging task, but essential for the creation of a complete biological profile. As such, the study of human variation between populations is important for the fields of biological and forensic anthropology, as well as medicine. Cranial and dental morphological variation have traditionally been linke...
Presentation
Full-text available
One of the crucial steps for the creation of the biological profile of an individual is the estimation of age at death. The choice of the method depends on the nature of the remains, the equipment available and the expertise of the forensic anthropologist, among others. In cases of very fragmented remains, microscopic methods remain one of the only...

Introduction Sex assessment is an essential step for completing the biological profile of unknown skeletal remains. Accurate sex estimation remains one of the main challenges in forensic anthropology and the need for replicable and reliable techniques led to development of a large number of methods, catered to different possible scenarios. This stu...
Article
The estimation of ancestry is an essential benchmark for positive identification of heavily decomposed bodies that are recovered in a variety of death and crime scenes. This is especially true when reconstructing the biological profile of the deceased as most methods for sex, age and stature estimation are population-specific. Ancestry estimation m...
Article
Introduction Age estimation methods using MRI are dependent on staging systems used in T1, T2 and fast spin-echo proton density-weighted sequences. The staging system created by Dedouit [1] from images obtained by fast spin-echo proton density-weighted MRI sequences depends on the assessment of horizontal cartilage hyperintensity. Images obtained b...
Article
Histology of dry bone tissue has many scientific applications. The histological analysis of bone requires the production of good quality thin sections. Many researchers have developed new histological techniques and/or they have refined existing ones. In this paper, we describe a revision of histological techniques for obtaining thin sections from...

This study investigates disruptions in bone metabolism using bone histomorphometry in individuals with chronic metabolic diseases (CMD) and their effect on histological age estimation methods. Thirty six samples (12 pathological and 23 controls) from the 4-6th left ribs are taken from autopsy cases from two forensic departments in Greece and Albani...
Conference Paper
Full-text available
Age estimation is crucial for the identification of human remains and the microscopic approach is the only option when the remains are very fragmented. Many histological age estimation techniques have been developed in the last forty years and in order to ensure the accuracy and reliability of existing aging methods, validation studies must be carr...
Article
Full-text available
Sexual dimorphic variation between populations must be taken into consideration when applying existing methods on unrelated samples. Validation studies are extremely important to avoid misclassification and ensure high quality standards. This paper presents a test of a Southern European metric method on Greek-Cypriots (N=132) and Turkish (N=203)....
Article
The utilization of computed tomography is beneficial for the analysis of skeletal remains and it has important advantages for anthropometric studies. The present study investigated morphometry of left tibia using CT images of a contemporary Turkish population. Seven parameters were measured on 203 individuals (124 males and 79 females) within the 1...
Article
Os parietale partitum is a variable segmentation of the parietal bone. This manifests as a parietal division in the anteroposterior or superoinferior planes that is separated by an unusual suture and can be complete or incomplete. The existence of parietal divisions was observed and documented more than 260 years ago. The main objectives of this pa...

Most age estimation methods are proven problematic when applied in highly fragmented skeletal remains. Rib histomorphometry is advantageous in such cases; yet it is vital to test and revise existing techniques particularly when used in legal settings (Crowder and Rosella, 2007). This study tested Stout & Paine (1992) and Stout et al. (1994) histolo...
