Many traits currently used to assess sex using the pubic bone are subjective in nature. By measuring multiple aspects of the pubic bone, many novel data points and measurements were examined and found to be reliable indicators of biological sex. In particular, five measurements reliably classified sex using discriminant function analysis.

Anthropologists most often use the pelvis, which is the most sexually dimorphic element both morphologically and metrically. While nonmetric pubic bone features have been studied extensively, few metric studies have examined this individual bone for dimorphism. For this study, three observers examined three previously identified and ten novel measurements of the pubic body on a modern sample of isolated pubic bones from the Maricopa County Forensic Science Center (FSC), in Phoenix, Arizona (n = 400). A relationship between pubic body measurements and biological sex was demonstrated, with significant correlations. Discriminant function analyses found that five measurements, four of which were novel, discriminated between males (89%) and females (86%). Observer experience level did not significantly impact the results. These five measurements were reliable and show promise for inclusion...

They are rarely described in the literature; however, even though they present specific patterns. Through 41 cases, 10 at the forensic institute in Lille (France) and 31 at the New York City Office of Chief Medical Examiner (USA), plus 22 cases from the literature, specific locations and patterns of postmortem scavenging lesions are proposed. These lesions are mainly distributed in three locations: the face, especially the nose and the mouth (73.1%), the neck (43.1%), and the arm (shoulder/upper limb [29.2%], hand [26.8%]). We discuss the time span between death and scavenging, the consequences on identification, and comparison with outdoor settings. Outdoor scavenging lesions are mainly located on the trunk and limbs usually sparing the head, which strongly differs from indoor distribution and imply different animal motivations.

Specimens were collected from decedents of known age, sex, and race at the Forensic Science Center (FSC) in Phoenix, Arizona. The collection consists of pubic bones and fourth rib ends from 419 males and 211 females, ranging in age from 18 to 99. Age-at-death was estimated by three observers using the Suchey-Brooks method. The correlation results indicate that there are significant differences in the observed versus actual ages (r = 0.68169, p < 0.001) and that there are significant interobserver differences. No significant differences were found in the intra-observer tests. The FSC pubic bones were sorted based on morphology without knowing age. New descriptions and age ranges were created. A phase seven was described and is comprised of males and females over 70 years of age-at-death.

Five different human tissues (bone, tooth, hair, fingernails, and skin ⁄ muscle ⁄ fat) were immersed into six different corrosive agents. These agents consisted of hydrochloric acid, sulfuric acid, lye, bleach, organic septic cleaner, and Coca-Cola Ò soda. Tap water was used as a control. Tissue samples were cut to consistent sizes and submerged in the corrosive liquids. Over time, the appearance, consistency, and weight were documented. Hydrochloric acid was the most destructive agent in this study, consuming most tissues within 24 h. Sulfuric acid was the second most destructive agent in this study. Bleach, lye, and cola had no structural effects on the hard tissues of the body, but did alter the appearance or integrity of the hair, nails, or flesh in some way. The organic septic cleaner and tap water had no effect on any of the human tissue tested during the timeframe of the study.
