The reconstruction has replicated skin on one side and the skull with some of the underlying soft tissue on the other side. Both the reconstruction and a skull on a 28-foot-long skeleton mounted in the exhibit hall are copies of an original fossil that was found in Utah. When alive 150 million years ago, the predator Allosaurus had a powerful bite, deadly claws and a strong, agile body. Photo by Marcia L. Ledford, U-M Photo Services
