Mandible and Mandibular Teeth. The left mandible has new hairline cracks in the body, one on the lateral surface from the second premolar to second molar and four on the medial surface from the second premolar to 10 mm posterior to the socket for the third molar. The right mandible shows many small hairline cracks in the medial face of the ramus, but is otherwise intact. There are new, very thin mesiodistal cracks in the left first and second molars and a labio-lingual crack in the mesial root of the right canine. The right third molar has a crack across the mesial aspect of the root that extends into the buccal surface of the enamel just above the cemento-enamel junction.
All major bones show new, hairline cracks, usually oriented along collagen fibers.
This includes the left clavicle, both scapulae, both humeri, and both radii. In most cases, this minor cracking does not affect the scientific potential of the bones. However, in the left ulna, broad cracks have formed on either side of the break between the two proximal-most fragments. Two major cracks in each segment have widened to 1 to 2 mm and longitudinal sections of the bone appear ready to break away. During re-packaging, the Government's conservators gave this piece special attention to reduce the risk of breakage.
