That, in turn, allowed the researchers to determine where the fossil had originally been unearthed, among other details

Scientists have long used CT scans to peek inside fossil-bearing rocks, but the increasing use of 3D printers now enables them to make endless numbers of exact copies of those relics

The technique might even help museum folk speed up their analyses: By knowing what’s inside a lump of rock, researchers can determine which fossils are worth extracting, and which ones can wait

One expedition, in Tanzania, ran from 1909 to 1913 and brought back 235 tons of fossils, labeled with letters based on their locations.

The other fossils came from a 1909 discovery in Halberstadt, Germany. Those bones also used a letter-based label system

By comparing the scans to sketches of the long-ago digs, the researchers determined that the vertebra came from the Halberstadt dig in Germany
...

Cancel
The scans showed a fractured bone. Some of the cracks were no doubt from fossilization
...

Cancel
But one crunched-up corner was likely the result of the bombing
...

Cancel
To recreate the bone as it was before the bombing, the researchers took data from the CT scan and built a blueprint to 3D print the fossil

The researchers were even able to print the bone chip from the bombing damage, which fit into the rest of the vertebra like a puzzle piece.
