The 13,900-Year-Old Mastodon Rib Found With A Bone Point Still Inside — And The CT Scan That Put Hunters Before Clovis
Every site is the product of a specific, unlikely chain of events that allowed some things to survive while most things vanished.
The Manis rib is a dramatic example of this general truth: it survived because the evidence literally got locked inside another piece of evidence that happened to be more durable.
Returning To The Rib
The mastodon rib from the Manis site is in a laboratory.
It has been there, in one institution or another, since Carl Gustafson excavated it in the late 1970s.
It has been examined visually, radiographed, CT-scanned, subjected to protein analysis, digitally segmented, and 3D reconstructed.
