Study Notes
Determination of Sex
- Male and female skeletons exhibit differences in general shape and size, known as sexual dimorphism.
- Some features may be more pronounced as "male" or "female"; sex is determined by the majority of traits observed.
- For instance, if a skull has more female-like traits, it is classified as female despite some male characteristics.
- Asian male remains are generally less robust compared to Native American female skeletons.
- Determining sex in infants and juveniles is challenging, as their skeletons commonly appear female until after puberty.
Key Skull Characteristics for Sex Determination
- General Size: Males are more robust, while females are more gracile.
- Nuchal Crest: Males have well-defined nuchal lines; females present smooth occipital surfaces.
- Mastoid Process: Larger in males; smaller in females.
- Supra-orbital Margin: Males display thicker, rounder borders; females have thin, sharp margins.
- Supra-orbital Ridge: More prominent in males; often little prominence in females.
- Mental Eminence: Males have squarish chins with greater projection; females' chins are more pointed.
- Gonial Angle: Males have a flared jaw angle (around 90 degrees); females typically have a less obtuse angle.
Determination of Age
- Various methods exist to ascertain the age at death of skeletal remains, with some methods more effective for juveniles and others for adults.
- Age classes used for skeletal remains include fetal, infant, child, adolescent, young adult, middle adult, and old adult stages.
Skull Aging Techniques
- The skull is a reliable structure for age determination, second only to the os coxae.
- Cranial sutures close progressively as individuals age, with a grading system from open to completely obliterated.
- Anterior sutures fuse first, followed by posterior sutures; closure rates can vary among individuals.
- The spheno-occipital synchondrosis is a strong indicator of age, fusing between 20 and 25 in over 95% of populations.
Alternative Age Determination Methods
- Subadult remains can be aged using dental eruption, epiphyseal union, and dental attrition.
- Adult remains utilize dental attrition, cranial suture closure, and changes in the pubic symphysis for age estimation.
Determination of Stature
- Long bone length correlates with stature, with variations seen across populations and between sexes.
- Researchers have created specific formulas for estimating stature based on skeletal remains, which may introduce errors when applied to archaeological specimens.
Paleopathology
- The study of ancient diseases revealed through skeletal remains requires precise measurement techniques for accuracy in analysis.
