CT scan and 3-D print help scientists reconstruct an ancient mollusk
Date:9/19/2012

the origin of modern chitons, Vinther could demonstrate that multiplacophorans are stem group chitons.

"We can now demonstrate that multiplacophorans are distant relatives of the modern chitons, which did not evolve until later in Earth history," said Vinther. "We can also show that they evolved a number of characteristics seen in some modern chitons convergently."

The CT scan was integral to the project, allowing the scientists to see below the surface of the fossil.

"CT scanning is an extremely powerful technique for paleontologists," said Vinther, "since we can look inside fossils without destroying them."

Vinther and Horn describe the process of creating the model in a video produced by the Jackson School of Geosciences and hosted online by National Geographic at http://news.nationalgeographic.com/news/2012/09/120918-ancient-mollusk-reconstruction-3d-animals/.

The original fossil was discovered 10 years ago in Ohio by private collector and co-author George Kampouris, who donated it to the Cincinnati Museum of Natural History.
