Chief preparator Dr. Ken Carpenter adjusts a cast of a baby stegosaur to be installed in the Prehistoric Journey dinosaur hall. This baby is actually a composite made from casts of two different fossil finds, one in Colorado, and the other in Wyoming. The stegosaur fossil discovery in Wyoming is significant because it includes the first baby stegosaur plate ever found; before this discovery, paleontologists were uncertain as to whether juvenile stegosaurs actually had plates. The baby plate, which is stored in the DMNS collections, was donated by Cliff Miles of Western Paleontological Laboratories. © 2000 DMNS. All rights reserved.
