Beyond Taphonomy: Exploring Craniometric Variation Among Anatomical Material.

Area of Science:

• Forensic Anthropology
• Bioarchaeology
• Human Osteology

Background:

• Anatomical crania are sometimes misidentified as human remains in forensic anthropology.
• Distinguishing anatomical specimens from human remains is crucial for accurate forensic casework.

Purpose of the Study:

• To determine if anatomical crania represent a homogenous group or a mix of populations.
• To assess the origin and taphonomic history of anatomical specimens.

Main Methods:

• Craniometric analyses of 21 interlandmark distances from 85 anatomical preparations.
• Statistical homogeneity testing using the Defrise-Gussenhoven test on pairwise distance measures.
• Calculation of pooled within-sample variance/covariance matrix for distance measures.

Main Results:

• Twenty-two percent (66 of 300) of pairwise combinations were statistically significant (p ≤ 0.05).
• The observed homogeneity suggests a common origin, likely from the Indian subcontinent or West Asia.
• The data indicate anatomical material forms a moderately homogenous group with a shared taphonomic history.

Conclusions:

• Anatomical crania, while exhibiting some diversity, can be considered a moderately homogenous group.
• The findings support a probable shared geographic origin (India/West Asia) and taphonomic history for these specimens.
• This research aids in the proper identification and interpretation of anatomical material in forensic contexts.
