Bioarchaeology Pelvic Trauma & Mass Grave Casualty Analyzer

Pelvic Girdle & Vascular Trauma Vector Stage Selected: Right Iliac Fossa (Perimortem Lance Impact)

Attacker Stance

Strike Elevation -32°

Strike Azimuth 18.5°

Penetration Depth 42.5 mm

Injury Classification

Perimortem sharp-projectile penetrating pelvic trauma

Lethality Assessment

Fatal (common iliac / femoral vessel transection within seconds)

Biomechanical Signature

Smooth beveled entry cortex with inner tabular radiating micro-fissures and retained metallic oxidation rim

Cohort Pelvic Rate

18.6% of analyzed cohort exhibiting lower abdominal / pelvic girdle perimortem trauma

Bone State & Taphonomic Distinction

Plastic deformation active: Organic collagen matrix creates acute-angled smooth beveled entry wounds, hinged bone flakes, and circular concentric stress lines indicative of trauma at or near time of death.
