How Tycoons Created the Dinosaur - Issue 107: The Edge

The dinosaur is a chimera. Some parts of this complex assemblage are the result of biological evolution. But others are products of human ingenuity, constructed by artists, scientists, and technicians in a laborious process that stretches from the dig site to the naturalist's study and the museum's preparation lab. The mounted skeletons that have become such a staple of natural history museums most closely resemble mixed media sculptures, having been cobbled together from a large number of disparate elements that include plaster, steel, and paint, in addition to fossilized bone. When standing before one of these towering creatures, such as the T. rex skeleton named Sue in Chicago's Field Museum of Natural History, it is surprisingly difficult to distinguish which features are ancient and which ones are modern, where prehistory ends and imagination begins. If dinosaurs in museums are chimeras, their prehistoric antecedents are unobservable entities. In this respect, dinosaurs resemble subatomic particles like electrons, neutrons, and positrons. Both are inaccessible to direct observation, but for different reasons.
