Oa. Ubelaker et Bj. Adams, DIFFERENTIATION OF PERIMORTEM AND POSTMORTEM TRAUMA USING TAPHONOMIC INDICATORS, Journal of forensic sciences, 40(3), 1995, pp. 509-512
Skeletal remains discovered at a construction site in Georgia display
classic ''butterfly'' fractures on several long bones. Although this f
racture pattern is usually associated with perimortem trauma, in this
case taphonomic indicators demonstrate that they can also occur on dry
defleshed bone. Variations in bone color at the fracture sites indica
te recent postmortem trauma. Analysis of the directions of force and p
oints of impact indicates that the bones were most likely disarticulat
ed when the trauma occurred.
