Only ten Archaeopteryx fossils have been found and studied. These specimens have undergone extensive visual analyses and even CT scans in the past, but never anything as comprehensive as the X-ray imaging researchers are utilizing at SSRL. Here, researchers are making the first maps of the chemical elements hidden within one of the best preserved specimens, possibly including remnants of soft tissue—not just bone. Approximately 16 by 16 inches (40 by 40 centimeters) in size, the Thermopolis specimen was originally discovered near Solnhofen, Germany, and is now owned by the Wyoming Dinosaur Center, located in Thermopolis, Wyoming.
