The 13,900-Year-Old Mastodon Rib Found With A Bone Point Still Inside — And The CT Scan That Put Hunters Before Clovis
Fragments That Did Not Look Like A Weapon
The first thing the CT scans revealed was the full extent of the embedded material.
What visual inspection had suggested was a cluster of fragments — a few pieces of dense bone penetrating the rib — turned out to be more complex than it had appeared.
The CT images showed that the embedded material occupied a channel that had been driven through the cortical bone of the rib’s outer surface and into the trabecular interior.
The channel was roughly conical in shape, wider at the entry point and tapering toward the interior — consistent with an impact that had driven a pointed object through the outer wall and into the body of the rib.
