Visualizing the past: Nondestructive imaging of ancient fossils
Date:11/11/2013

By integrating high-resolution X-ray imaging (termed microCT), 3D image segmentation, and computer animation, a new study conducted by Carole Gee at the University of Bonn, Germany, demonstrates the visualization of fossils without destroying the material. Traditional techniques, such as thin-sectioning, require investigators to physically cut up the fossil in order to observe internal structures. Dr. Gee, however, has now successfully applied microCT to visualize silicified conifer seed cones as old as 150 million years without cutting, sawing, or damaging the specimens in any way.

Well-preserved, informative plant fossils are few and far between. Specimens with reproductive organs are especially scarce but are invaluable to understanding plant evolution and ancient diversity. When such fossils are unearthed, they are lucky finds and often only single specimens are present.

"Because each specimen is precious, the main goal of this research was to study the internal structure of fossil conifer seed cones without destroying or damaging them," explains Gee.

Using this technique, X-ray images, similar to those used in the medical field, are captured, providing virtual cross-sections of the specimen, without ever cutting into the sample. These images are then combined, producing a 3D reconstruction. This study, along with computer animations and detailed figures presenting microCT imaging, is freely available for viewing in the November issue of Applications in Plant Sciences.

In the study, Gee demonstrates how this technique allows the observation of internal features such as seeds, vascular tissue, and cone scales. Furthermore, by adding artificial color to highlight certain structures or tissues, such as a row of seeds within a cone, the natural pattern of growth was evident. As Gee observes, "It's amazing to visualize internal structures
