Scientists study fossils without having to remove them from rock

Here you can see a lump of rock with embedded fossils of bird bones trapped in the matrix. Below the rock are 3D printed models of those same fossils, created by paleontologist Brett Nachman. Other scientists captured the fossils inside the rock using CT scans that can see through the stone with the help of x-rays.

Last year, journalist Charles Choi wrote about the massive backlog of fossils in storage at most museums and suggested the possibility of using this kind of technology to study fossils that might not otherwise ever be removed from the hard matrix. Now, Charles is writing about people like Nachman who are doing just that — using technology to get at fossils that are too labor intensive to study.
